Death by PowerPoint is still a killer. The solution? Invest in design

Design is the silver bullet for research. Make your findings interesting, simple and easy to understand and the world will take notice. If it intuitively makes sense your findings will spread like wildfire. If not, it’ll die on the screen.

Recently there’s been a hive of innovation in research: online; mobile; social… the list goes on. But this list is all just different methods of collecting information. What has been more resistant to change is how we present that information.

If research wants to have more impact with decision makers, we need to be more palatable for them. This means translating the findings into something they can intuitively understand. The problem is it is easiest to present people with the same representations used by the research: graphs and numbers. This is not the way it ought to be. We need to present decision makers with information in the format most appropriate to their needs and to the decisions they need to make. What is wrong with a lot of presentations today is their design, which requires people to behave in research-centred ways, picking apart data and numbers, ways for which many people are not well suited. What we find, then, is that the form of representation makes a dramatic difference in the ease of understanding the research.

There are two tasks for any audience – finding the relevant information and deciding upon the desired action. The design of the research presentation can either help or hinder this process. We believe we must work harder to make sure the design of the presentation does not get in the way; as if designed inappropriately we are at risk of losing the audience and not giving them the opportunity to find the information and make the most appropriate business decisions.

To combat this, we will argue there are three major changes researchers need to undertake:

  1. Get better at PowerPointToo often the presentation is a data dump of raw findings from the methodology. Little thought goes into how a novice should understand it. Teams need to be taught design theory and trained in how to maximise the potential of PowerPoint. For example, learning about Gestalt psychology will help researchers know how to space, design and layout results.
  2. Go beyond PowerPointWe need to loosen our grip on PowerPoint and embrace other forms of information delivery. A lot of times a deck of slides isn’t the most appropriate format. Why not put together a video debrief of your findings that brings the information to life? Why not create a bookmark with the top 5 takeaways for your stakeholders? Why not mock up an example advert that best reflects what consumers would most respond to?
  3. Hire a designerWe believe having an in-house designer is now as essential as having an in-house data analyst. Not only do designers bring a skill set and design experience that they can leverage, they also are unshackled by years of research training and so bring fresh eyes and perspectives to research, making the output they create at once more relatable and accessible for any audience.

We believe that taking on even just one of these changes will greatly enhance the impact and relevance of research to senior decision makers

Nowadays people have very hectic and busy lifestyles – trying to balance work, home and a social life is increasingly challenging. However, companies are becoming more attuned to this and starting to adapt their products to suit.

Lack of time is typically the main reason for lack of participation in sport or gym attendance. However, it remains hugely popular, with the number of people taking part every week reaching around 16 million and the number of fitness centre members in the UK being the highest ever.

Maybe this is because gyms are increasing the number of classes or reducing their length to be more flexible. For example, some gyms are now promoting 30 minute classes, which are easier to squeeze into your lunch break. Some offices even have gyms that you can pop to whenever in the working day to help cater for busy lifestyles. Also having exercise studios entirely dedicated to one activity (such as yoga) means there are more classes for people to choose from.

Participation in high-intensity exercise classes and activities, like spin and boxercise, continue to attract large numbers of people, potentially rivalling more traditional sports such as football, netball and hockey. Outdoor activities such as bootcamp and Parkrun are also increasing in popularity which are seen as a highly sociable way to exercise. Maybe this is people’s way of ticking both the ‘exercise’ and ‘socialise’ boxes on their to-do lists?

More established activities like yoga and pilates are still gaining in popularity as well. These classes are expected to provide both physical and mental benefits – such as increased muscle strength and tone, improved athletic performance, stress relief and encouraging relaxation. People can therefore achieve a healthier lifestyle in a more compact way, which saves time relative to completing several separate activities to achieve the same benefits.

As well as exercise companies, nutrition companies are also adapting to people’s hectic lifestyles. Nutrition is becoming more of a focus and healthy eating is a main element of having a healthy lifestyle. We have therefore seen the rise in trends such as The Body Coach, Joe Wicks, who promises that you’ll be able to lose weight, despite eating more food and spending less time at the gym. He also has a 15 minute meals cookbook that caters for those lacking time in the evenings and suggests quick exercises you can do in the comfort of your own home.

Adapting to hectic lifestyles has also paved the way for food companies such as HelloFresh or Gousto. Their USP is that they deliver fresh ingredients and healthy recipes straight to your doorstep. This means you can get back from a busy day at work and have your dinner all bought and planned out for you – all you have to do is follow the recipe. The next step on from this is Deliveroo that actually delivers healthy food options straight to the doorstep of either your home or office ready for consumption! So now when you get home from work late and cooking is the last thing on your mind, instead of the traditional Chinese or Indian takeaways you can now get Pho or Sushi delivered to your door!

So having a healthy lifestyle doesn’t appear to be a fad or a trend, it’s the way things are nowadays. We have already seen intersections between health and exercise but this also begs the question – where will this go? What’s next for healthy lifestyles?

Maybe exercise and retail companies will start partnering up. For example, introducing grocery stores at the gym to save having to do a food shop later that evening. Or they could pair up in a totally different way. It may be counter-intuitive but BeerYoga is something that I stumbled upon recently where attendees can drink beer whilst doing yoga. Now this ticks all the boxes – social, mental and physical. Will that mean that WinePilates or SushiSpin emerge as trends as well? It’s fair to say some of these may seem slightly odd now but many fads do before they become accepted into society.

There’s a great book by Columbia Business School associate professor, William Duggan, called Strategic Intuition. The book posits that intuition is ‘the selective recombination of previous elements into a new whole.’

One of Duggan’s examples of intuitive thinkers is one of Napoleon’s early campaigns. When ordered to re-take the port of Toulon from the British invaders via frontal assault ‘with the sword and bayonet’, Napoleon suggests an alternative strategy; to take the smaller fort of L’Agiuilelette, which overlooks the port of Toulon. Against the received wisdom of his peers and commanders, Napoleon goes ahead with his plan, takes the fort, and in doing so terrifies the British into leaving Toulon and sets his path for Emperor of Europe.

What’s interesting here – and why Duggan raises this example from history – is how Napoleon came to his plan, by bringing together abstract parts of his memory and experience: his reading of the contour maps on the area of Toulon; his knowledge of how best to deploy light cannon and his understanding of past British defeats. The contour maps showed him that the fort of L’Aiguilette occupied high ground over Toulon; from his light cannon experience he knew he could take the cannon up to the fort and deploy them overlooking Toulon and the British fleet; and his understanding of past British defeats at Yorktown and the Siege of Boston taught him that the British would never again risk being cut off from their navy.

None of those thoughts – contour maps; light cannon; British defeats – were taught to Napoleon together. Instead, as Duggan argues, it is the ‘selective recombination of previous elements into a whole.’

Have you ever had an idea flash into your mind? A random thought disconnected from what you’re trying to concentrate on – that’s strategic intuition. And it’s proof that our brains are non-linear. Try as we might, we struggle to focus on a single thought for a long period of time. Rather our brains are adept at working in our subconscious and delivering fresh ideas and insights at a moment’s notice.

You can’t help but think of multiple things at once, or just as likely thinking multiple things about one idea at once. In contrast, however, Word, PowerPoint and Excel, by their very nature, are linear. Word splits information over different pages, PowerPoint chunks information in slides and Excel breaks then across tabs. And all are subject to the limitations of screen size. This linear function is in direct odds to the brain’s non-linear thinking, forcing you to work to their restrictions.

By chunking information into different pages, slides or tabs it also forces the brain to change its functioning.  When all the information is displayed at once, the brain can focus on analysis and connecting information. We can tap into the very strength of our brain – making random, subconscious associations. However, when chunked over different pages, slides and tabs the brain must first remember all the information it has been exposed to before it can then begin to analyse and connect it. This exerts increased cognitive load on the brain and causes a significant break down in your brain’s ability to create those connections.

So, what if we moved away from linear formats and embraced our brain’s capacity for non-linear thinking, for sparks of insight. This is where the power of Post-It notes – or record cards, or just scraps of paper – come in. 

When first planning or thinking of an idea or concept, a good idea is to plot your thoughts on Post-It notes. Each one holding one thought. And filling your table, or wall, or desk with them. The beauty of this is that it embraces our non-linear brain. A random thought or idea can be jotted down and placed to the side, not distracting your attention by needling your mind but also addressed and captured quickly during it’s fleeting appearance. Overall, Post-It planning seems to help in three main ways:

Making connections

Post-It notes and record cards allow for the creation of non-linear narratives. With the use of Post-It notes, or record cards and a box of pins, you can map out an entire concept visually, highlighting interconnecting thoughts and relationships – celebrating the very non-linear thinking our brains champion and computers cannot copy. As an individual activity working with Post-Its allows us to re-arrange ideas as we go. Once we have captured all our thinking on multiple Post-Its we can then begin to rearrange them over and over again, in different orders and ways until we are happy with our outcome.

A free-form structure

By filling a wall with Post-It notes we are avoiding a linear path through the information, rather we are creating a free-form structure. Every time you look at the wall, or return to the room, you can look at the Post-It notes in a different order. And perhaps draw out new meaning or sense from it. It also means you’re not enforcing a structure on others, they too can create their own path through the information – a very effective element when developing ideas and concepts with others.

Fostering collaboration

When working together, cards and post-it notes invite displayed thinking. By committing our thoughts to paper and then arranging them on a wall we can easily invite others to see our thinking; but just as easily others can begin to add to, edit or rationalize our thoughts, so that together we can create a shared cognition about an idea and together create a common understanding. This shared activity fosters creativity, especially as any person can re-arrange cards.

So, before you next fire up your laptop ask yourself, would I be more creative if I used Post-Its and embraced my brain’s non-linear thinking?

Imagine you’re a digital marketer for an online retailer specialising in fitness gear. You’ve just launched a new line of eco-friendly yoga mats, and you’re tasked with maximising sales through your website. You test two different product page versions to see which drives more purchases. 

Version A features a prominent “Limited Time Offer” banner at the top, while Version B includes a series of customer testimonials right beneath the product title. The results of this A/B test could significantly affect your sales figures and offer deeper insights into what motivates your customers to buy.

Such is the power of A/B testing, a method companies of all sizes use to make data-driven decisions that refine user experiences and improve conversion rates. 

A/B testing provides a data-driven solution to optimise website effectiveness without the guesswork. By comparing two versions of a page or element directly against each other, brands can see which changes produce positive outcomes and which ones do not, leading to better business results and a deeper understanding of customer behaviour.

Whether you’re looking to increase conversion rates, enhance user engagement, or drive more sales, effective A/B testing is the key to achieving your goals precisely and confidently.

A/B testing, or split testing, is a method in which two versions of a webpage or app are compared to determine which performs better. Imagine you’re at the helm of a ship; A/B testing gives you the navigational tools to steer more accurately toward your desired destination—increased sales, more sign-ups, or any other business goal. It involves showing the original version (A) and a modified version (B), where a single element may differ, such as the colour of a call-to-action button or the layout of a landing page, to similar visitors simultaneously. The version that outperforms the other in achieving a predetermined goal is then used moving forward.

The Importance of A/B testing and ROI

The compelling advantage of A/B testing is its direct contribution to enhancing business metrics and boosting return on investment (ROI). 

A recent study by eConsultancy shows that companies that use A/B testing are twice as likely to report significant improvements in conversion rates. 

Online retailers frequently use A/B testing to optimise website leads and increase conversion rates. This includes split testing product pages and online advertisements, such as Google Shopping Ads. By A/B testing different product page layouts, retailers can identify a version that increases their sales, impacting annual revenue. Similarly, SaaS providers test and optimise their landing pages through A/B testing to find the version that increases user sign-ups, directly improving their bottom line.

A/B testing is less about guessing and more about evidence-based decision-making, ensuring every change to your interface is a strategic enhancement, not just a cosmetic tweak.

Preparing for A/B Testing

1. Setting Objectives

Before launching an A/B test, defining clear, measurable objectives is critical. These objectives should be specific, quantifiable, and aligned with broader business goals. Common goals include increasing conversion rates, reducing bounce rates, or boosting the average order value. The clarity of these objectives determines the test’s focus and, ultimately, its success.

2. Identifying Key Elements to Test

Choosing the right elements on your website for A/B testing can significantly affect the outcome. High-impact elements often include:

  • CTAs: Testing variations in the text, color, or size of buttons to see which drives more clicks.
  • Layouts: Comparing different arrangements of elements on a page to determine which layout keeps visitors engaged longer.
  • Content: Tweaking headlines, product descriptions, or the length of informational content to optimise readability and conversion.
  • Images and Videos: Assessing different images or video styles to see which leads to higher engagement or sales.

3. Understanding Your Audience

Effective A/B testing requires a deep understanding of your target audience. Knowing who your users are, what they value, and how they interact with your website can guide what you test and how you interpret the data from those tests.

Data Analytics Snapshots:

Utilising tools like Google Analytics, heatmaps, or session recordings can provide insights into user behaviour. Heatmaps, for example, can show where users are most likely to click, how far they scroll, and which parts of your site draw the most attention. These tools can highlight areas of the site that are performing well or underperforming, guiding where to focus your testing efforts.

Importance of Audience Insights:

Understanding user behaviour through these tools helps tailor the A/B testing efforts to meet your audience’s needs and preferences, leading to more successful outcomes. For instance, if heatmaps show that users frequently abandon a long signup form, testing shorter versions or different layouts of the form could reduce bounce rates and increase conversions.

These preparatory steps—setting objectives, identifying key elements, and understanding the audience—create a strong foundation for successful A/B testing. By meticulously planning and aligning tests with strategic business goals, companies can ensure that their efforts lead to valuable, actionable insights that drive growth and improvement.

Designing A/B Tests

Developing Hypotheses

A well-crafted hypothesis is the cornerstone of any successful A/B test. It sets the stage for what you’re testing and predicts the outcome. A strong hypothesis is based on data-driven insights and clearly states what change is being tested, why, and its expected impact.

Guidance on Formulating Hypotheses:

  • Start with Data: Analyze your current data to identify trends and areas for improvement. For instance, if data shows a high exit rate from a checkout page, you might hypothesise that simplifying the page could retain more visitors.
  • Be Specific: A hypothesis should clearly state the expected change. For example, “Changing the CTA button from green to red will increase click-through rates by 5%,” rather than “Changing the CTA button colour will make it more noticeable.”
  • Link to Business Goals: Ensure the hypothesis aligns with broader business objectives, enhancing its relevance and priority.

Examples:

  • Good Hypothesis: “Adding customer testimonials to the product page will increase conversions by 10% because trust signals boost buyer confidence.”
  • Poor Hypothesis: “Changing things on the product page will improve it.”

Creating Variations

Once you have a solid hypothesis, the next step is to create the variations that will be tested. This involves tweaking one or more elements on your webpage based on your hypothesis.

Instructions for Creating Variations:

  • Single Variable at a Time: To understand what changes affect outcomes, modify only one variable per test. If testing a CTA button, change the color or the text, but not both simultaneously.
  • Use Design Tools: Utilise web design tools to create these variations. Ensure that the changes remain true to your brand’s style and are visually appealing.
  • Preview and Test Internally: Before going live, preview variations internally to catch potential issues.

Choosing the Right Tools

Selecting the appropriate tools is crucial for effectively running A/B tests. The right tool can simplify testing, provide accurate data, and help interpret results effectively.

By following these steps—developing a strong hypothesis, creating thoughtful variations, and choosing the right tools—you can design effective A/B tests that lead to meaningful insights and significant improvements in website performance. This strategic approach ensures that each test is set up for success, contributing to better user experiences and increased business outcomes.

Implementing A/B Tests

Effective implementation of A/B tests is critical to achieving reliable results that can inform strategic decisions. 

Test Setup and Configuration

Setting up an A/B test properly ensures that the data you collect is accurate and that the test runs smoothly without affecting the user experience negatively.

Step-by-step Guide on Setting Up Tests:

  • Define Your Control and Variation: Start by identifying your control version (the current version) and the variation that includes the changes based on your hypothesis.
  • Choose the Type of Test: Decide whether you need a simple A/B test or a more complex split URL test. Split URL testing is useful when major changes are tested, as it redirects visitors to a different URL.
  • Set Up the Test in Your Chosen Tool: Using a platform like Google Optimise, create your experiment by setting up the control and variations. Input the URLs for each and define the percentage of traffic directed to each version.
  • Implement Tracking: Ensure that your analytics tracking is correctly set up to measure results from each test version. This may involve configuring goals in Google Analytics or custom-tracking events.

Interactive Checklists or Setup Diagrams:

A checklist can help ensure all steps are followed, such as:

  • Define control and variation
  • Choose testing type
  • Configure the test in the tool
  • Set traffic allocation
  • Implement tracking codes

Best Practices for Running Tests

Once your test is live, managing it effectively is key to obtaining useful data.

Tips for Managing and Monitoring A/B Tests:

  • Monitor Performance Regularly: Check the performance of your test at regular intervals to ensure there are no unexpected issues.
  • Allow Sufficient Run Time: Let the test run long enough to reach statistical significance, usually until the results stabilise. You have enough data to make a confident decision.
  • Be Prepared to Iterate: Depending on the results, be prepared to make further adjustments and rerun the test. Optimisation is an ongoing process.

Visual Dos and Don’ts Infographics

To help visualise best practices, create an infographic that highlights the dos and don’ts:

  • Do: Test one change at a time, ensure tests are statistically significant, and use clear success metrics.
  • Don’t Change multiple elements at once, end tests prematurely, and ignore variations in user behaviour.

Statistical Significance and Sample Size

Understanding these concepts is crucial for interpreting A/B test results accurately.

Explanation of Key Statistical Concepts:

  • Statistical Significance: This measures whether the outcome of your test is likely due to the changes made rather than random chance. Typically, a result is considered statistically significant if the probability of the result occurring by chance is less than 5%.
  • Sample Size: The number of users you need in your test to reliably detect a difference between versions. A sample size that is too small may not accurately reflect the broader audience.

Graphs and Calculators:

  • Provide a graph showing how increasing sample size reduces the margin of error, enhancing confidence in the results.
  • Link to or embed a sample size calculator, allowing users to input their data (like baseline conversion rate and expected improvement) to determine how long to run their tests.

By following these guidelines and utilising the right tools and methodologies, you can implement A/B tests that provide valuable insights into user behavior and preferences, enabling data-driven decision-making that boosts user engagement and business performance.

Analyzing Test Results

Once your A/B test has concluded, the next crucial step is analyzing the results. This phase is about interpreting the data collected, understanding the statistical relevance of the findings, and making informed decisions based on the test outcomes.

Interpreting Data

Interpreting the results of an A/B test involves more than just identifying which variation performed better. It requires a detailed analysis to understand why certain outcomes occurred and how they can inform future business decisions.

How to Read Test Results:

  • Conversion Rates: Compare the conversion rates of each variation against the control. Look not only at which had the highest rate but also consider the context of the changes made.
  • Segmented Results: Break down the data by different demographics, device types, or user behaviours to see if there are significant differences in how certain groups reacted to the variations.
  • Consistency Over Time: Evaluate how the results varied over the course of the test to identify any patterns that could influence your interpretation, such as a weekend vs. weekday performance.

Statistical Analysis

A deeper dive into the statistical analysis will confirm whether the observed differences in your A/B test results are statistically significant and not just due to random chance.

Understanding Statistical Significance and Other Metrics:

  • P-value: This metric helps determine the significance of your results. A p-value less than 0.05 typically indicates that the differences are statistically significant.
  • Confidence Interval: This range estimates where the true conversion rate lies with a certain level of confidence, usually 95%.
  • Lift: This is the percentage increase or decrease in the performance metric you are testing for, calculated from the baseline of the control group.

Making Informed Decisions

With the data interpreted and the statistical analysis complete, the final step is to decide how to act on the insights gained from your A/B test.

Guidelines on How to Act on Test Results:

  • Implement Winning Variations: If one variation significantly outperforms the control, consider implementing it across the site.
  • Further Testing: If results are inconclusive or the lift is minimal, running additional tests with adjusted variables or targeting a different user segment may be beneficial.
  • Scale or Pivot: Depending on the impact of the changes tested, decide whether to scale these changes up to affect more of your business or to pivot and try a different approach entirely.

Decision Trees or Flowcharts:

Create a decision tree or flowchart that outlines the decision-making process following an A/B test. This could include nodes that consider whether the test was statistically significant, whether the results align with business goals, and what follow-up actions (like further testing, full implementation, or abandonment of the change) should be taken based on different scenarios.

By thoroughly analyzing A/B test results through data interpretation, statistical analysis, and strategic decision-making, organisations can ensure that they are making informed decisions that will enhance their website’s user experience and improve overall business performance. This data-driven approach minimises risks associated with website changes and ensures that resources are invested in modifications that provide real value.

Beyond Basic A/B Testing

Once you have mastered basic A/B testing, you can explore more sophisticated techniques that offer deeper insights and potentially greater improvements in user experience and conversion rates. This section delves into advanced testing strategies and the importance of ongoing optimisation through iterative testing.

Advanced Testing Techniques

Advanced testing methods allow you to explore more complex hypotheses about user behaviour and website performance, often involving multiple variables or entire user journeys.

Multivariate Testing (MVT):

  • Overview: Unlike A/B testing, which tests one variable at a time, multivariate testing allows you to test multiple variables simultaneously to see which combination produces the best outcome.
  • Application: For example, you might test different versions of an image, headline, and button on a landing page all at once to determine the best combination of elements.
  • Benefits: This approach can significantly speed up the testing process and is particularly useful for optimising pages with multiple elements of interest.

Multipage Testing:

  • Overview: Also known as “funnel testing,” this technique involves testing variations across multiple pages that make up a user journey or funnel.
  • Application: You might test variations of both the product and checkout pages to see which combination leads to higher conversion rates.
  • Benefits: Multipage testing helps ensure consistency in messaging and user experience across multiple stages of the user journey, which can improve overall conversion rates.

Continuous Improvement and Iteration

The goal of A/B testing is not just to find a winning variation but to continually refine and enhance your website based on user feedback and behaviour.

Importance of Ongoing Optimisation:

  • Iterative Process: Optimisation is an ongoing process that involves continually testing and refining website elements based on user data and business objectives.
  • Learning from Each Test: Each test provides valuable insights into whether a variation wins. These insights can inform future tests, leading to better user experiences and higher conversion rates.

Iterative Testing Strategies:

  • Start with Broad Tests: Begin with broader tests to identify which elements have the most significant impact on user behaviour.
  • Refine and Repeat: Use the insights gained to refine your hypotheses and test more specific variations.
  • Expand Testing: Once you’ve optimised major elements, expand your testing to less prominent components that could still affect user experience and conversions.

Timelines and Case Studies:

  • Timeline Example: Show a timeline that outlines an annual testing strategy, with phases for broad testing, refinement, and expansion.
  • Case Study: Present a case study of a company that implemented continuous testing. Highlight how iterative testing helped them achieve a significant, sustained increase in conversion rates over time. For instance, a tech company could use iterative testing to fine-tune its sign-up process, resulting in a 50% increase in user registrations over a year.

By advancing beyond basic A/B testing and embracing more complex and continuous testing strategies, companies can optimise their websites more effectively and foster a culture of data-driven decision-making. This approach leads to improvements that align with user preferences and business goals, ensuring sustained growth and a competitive edge in the market.

Common Pitfalls and How to Avoid Them

A/B testing is a powerful tool for website optimisation, but common pitfalls can undermine its effectiveness. This section explores typical errors that occur during the testing process and provides strategies to ensure the validity and reliability of your tests.

List of Common Mistakes

Identifying Errors and Solutions:

  • Testing Too Many Changes at Once: It can make determining which change affected the outcome difficult.
    • Solution: Focus on testing one change at a time or use multivariate testing for simultaneous changes and analyze the impact of each element separately.
  • Not Allowing Enough Time for the Test to Run: Ending a test too soon can lead to conclusions that aren’t statistically significant.
    • Solution: Ensure each test runs long enough to collect adequate data, reaching statistical significance before making decisions.
  • Testing Without a Clear Hypothesis: Starting tests without a clear, data-backed hypothesis leads to unclear outcomes.
    • Solution: Develop a precise hypothesis for each test based on thorough data analysis and clear business objectives.
  • Ignoring User Segmentation: Different segments may react differently to the same change.
    • Solution: Segment your audience and analyze how different groups respond to each variation.

Visuals of Pitfalls vs. Best Practices:

  • Create side-by-side infographics showing examples of these mistakes versus best practices. For example, visually compare the outcome of a test that changed multiple elements simultaneously against one that tested a single change.

Ensuring Validity and Reliability

Maintaining the integrity of your A/B tests is crucial for obtaining reliable, actionable insights.

Tips on Maintaining Test Integrity:

  • Use Proper Randomisation: Ensure that the distribution of users between the control and test groups is random to avoid selection bias.
    • Tool Tip: Utilise tools that automatically handle randomisation to avoid manual errors.
  • Control External Factors: Holidays, marketing campaigns, or significant news events can skew test results.
    • Solution: Monitor external factors, adjust the testing period, or filter the data to account for anomalies.
  • Ensure Consistent Test Conditions: Changes in the testing environment or platform during the test can invalidate results.
    • Solution: Keep the testing conditions consistent throughout the test period and verify configuration settings regularly.
  • Validate Test Setup Before Going Live: A misconfigured test can lead to incorrect data interpretation.
    • Solution: Run a smaller pilot test or use a checklist to ensure every test element is correctly set up before full deployment.

Troubleshooting Guide with Graphic Aids:

  • Develop a troubleshooting guide that includes common scenarios where A/B test integrity might be compromised. Include flowcharts or decision trees that help identify and resolve issues such as data discrepancies, unexpected user behaviour, or sudden changes in conversion rates.
  • Example Graphic Aid: A flowchart that helps determine actions when test results seem inconsistent with historical data or benchmarks. Steps might include checking configuration settings, reviewing segmentation criteria, or extending the test duration.

By understanding and avoiding these common pitfalls and maintaining rigorous standards for validity and reliability, organisations can ensure that their A/B testing efforts lead to meaningful improvements and robust data-driven decisions. This approach not only enhances the effectiveness of current tests but also builds a foundation for future testing strategies that are even more successful.

A/B Testing Case Studies

A/B testing has proven to be a critical tool for businesses aiming to optimise their online presence based on data-driven decisions. Here, we delve into some specific real-life case studies from different industries, highlighting the successes and lessons from A/B testing.

Success Stories

E-commerce: Humana

  • Overview: Humana, a well-known health insurance company, conducted an A/B test to increase click-through rates on one of their primary campaign landing pages. They tested the simplicity and message of their banner and CTA.
  • Changes Tested: The original banner had a lot of information and a standard “Shop Medicare Plans” button. The test variation simplified the message and changed the button text to “Get Started Now.”
  • Results: The variation led to a 433% increase in click-through rates to the insurance plans page.

B2B: SAP

  • Overview: SAP, a leader in enterprise application software, tested the copy of their CTA on a product page. The hypothesis was that a more action-oriented CTA would increase engagement.
  • Changes Tested: The original CTA read “Learn more,” which was changed to “See it in action” in the variation.
  • Results: This simple change in wording resulted in a 32% increase in clicks.

.

Digital Media: The Guardian

  • Overview: The Guardian tested different wordings for their support and donation CTAs to determine which would more effectively encourage readers to contribute financially.
  • Results: The test revealed that a direct ask for contributions using emotive language resulted in a higher click-through rate than a more generic request for support.
  • Lesson: This A/B test highlighted the importance of emotional resonance in messaging, especially for non-profit or cause-based initiatives.

Travel Industry: Expedia

  • Overview: Expedia conducted A/B testing to optimise hotel booking conversions on their site by altering the display of discount offers.
  • Changes Tested: They tested the visibility and presentation of savings messages (e.g., showing a percentage off versus a specific dollar amount saved).
  • Results: Showing the amount of money saved led to a slight decrease in conversion rates, contrary to expectations.
  • Lesson: The test underscored the potential for “over-optimising” to backfire and the need to balance how offers are presented to avoid overwhelming customers.
