What is AB Testing?

AB testing is a method of experimentation used in digital marketing. It has become essential for optimizing the performance of an e-commerce site.


The principle of AB Testing is based on the collection of concrete data, enabling companies to make performance-based decisions.

AB-test-landing-page-ecommerce

In concrete terms, this method consists of comparing two versions of a web page or campaign element to see which achieves the best results.Β 

‍

Each version is shown to a similar group of users. By comparing the results obtained, we then determine which one generates the most conversions and engagement.

This article presents a complete guide to AB testing. Definition, test types, test optimization: let's take a look at the best practices.

1. What is AB Testing?Β 

Definition of AB Testing

‍

AB Testing, also known as split testing or A/B testing, is a scientific method of experimentation used in digital marketing πŸ§‘β€πŸ”¬

‍

Imagine comparing two versions of a web page or campaign element to see which gets the best results. Each version is shown to a group of similar users. Performance is analyzed to determine which converts more.

‍

The principle is based on the collection of statistical data. By using indicators such as click-through rate, add-to-cart or conversion rate, companies can make informed decisions based on real facts, rather than guesswork.


AB testing methods help to continually optimize pages and campaigns to maximize performance. In short, AB Testing is a scientific approach to improving the effectiveness of marketing strategies.

The importance of AB testing for e-commerce

AB testing is essential for e-commerce sites. It allows them tooptimize every aspect of their website to improve conversion rates πŸ“ˆ

‍

By testing different versions of product pages, landing pages or action buttons, e-tailers can identify what best meets their visitors' expectations.

‍

AB Testing also helps to reduce bounce rates and improve user experience. By understanding what works and what doesn't, e-tailers can adopt optimizations based on actual user preferences.

‍

These data-driven improvements generally translate into sales and revenue growth.

‍

2. Why do e-tailers love AB testing?

AB testing is a powerful tool for e-tailers. There are several reasons why they appreciate this method πŸ€”

‍

Firstly, AB testing enables continuous, measurable improvement in web page performance.Β 

what is AB-testing

‍

By testing different versions of pages or elements, e-commerce or media managers can determine exactly what works best for their specific audience.

‍

AB testing allows you to discover the elements of your site that boost conversions.

‍

By testing different versions of product pages, forms or CTAs, you can see which ones convert the most visitors into customers.

‍

Secondly, AB Testing reduces the risks associated with website changes.Β 

‍

Rather than making major changes based on guesswork, e-tailers can test changes gradually. This minimizes the risk of lost traffic or reduced sales.

‍

Secondly, AB testing is a solution for the agile development of e-commerce sites.Β 

‍

Technological solutions make it possible to carry out experiments without calling on technical teams. No more evolution requests that don't fit into the IT teams' roadmap πŸ˜…

‍

AB testing makes it possible to personalize the user experience.

‍

By adapting an e-commerce site to user preferences, you can personalize content, special offers and recommendations, improving customer engagement, satisfaction and loyalty.

‍

Finally, AB testing offers a great opportunity tooptimize the acquisition budget. By identifying the best practices for their audience, e-tailers can improve conversion and customer engagement, and maximize their media investments.

‍

3. The different types of AB Tests

There are several types of AB test that e-tailers can use to optimize their web pages and campaigns. Each type of test has its own advantages and can be adapted to suit the company's specific objectives.

different-types-AB-test

Simple A/B testing, the most widely used version

Simple A/B testing is the most common and basic form of AB Testing.

‍

It involves comparing two versions of the same page or element, called version A and version B.

‍

Users are randomly assigned to view one of the two versions.

‍

The performance of each version is then compared according to key metrics such as conversion rate and click-through rate.

‍

Multivariate testing, for testing several variables

Multivariate testing goes one step further by testing several variables simultaneously. It provides the opportunity to test several variables at the same time.Β 

‍

This method identifies the combinations of elements such as title, images, call-to-action button - or CTA - that have the greatest impact on overall performance.Β 

‍

This helps us understand how these elements interact with each other.

‍

Redirection test, or comparing two separate pages

‍

Redirection testing, or split URL testing, is used to compare completely different web pages.Β 

‍

Unlike simple A/B testing, which modifies elements on the same page, redirect testing sends users to completely separate URLs.Β 

‍

This type of test is useful for evaluating radically different page designs or for testing new landing pages.

‍

Real-time A/B testing

‍

Real-time A/B testing allows you to test modifications live on a website without creating separate static versions.Β 

‍

Changes are applied directly via an A/B testing tool, and performance is monitored in real time.

‍

This offers flexibility and speed of execution, ideal for rapid adjustments and continuous optimization.

‍

A/A and multi-page testing

The A/A test compares two identical versions to check the accuracy of a test tool's results.

‍

Multi-page testing analyzes changes on multiple pages within the same conversion funnel to optimize the overall user experience.

4. How to carry out an effective AB test

To achieve significant results with AB testing, it's important to follow a rigorous methodology.

‍

We have identified 8 key stages.

‍

realiser-AB-test-efficace

Define clear objectives

‍

The first step is to define your test objectives.Β 

‍

What would you like to improve? 🎯

‍

Increase conversion rate, improve engagement, increase time spent, reduce bounce rate or another indicator: identify what you want to achieve with your test.Β 

‍

Only well-defined objectives will enable you to accurately measure the success of your tests.

‍

Formulating Hypotheses

‍

Once you've established your objectives, formulate hypotheses to apply to your AB Test, on what you plan to improve and why.Β 

‍

For example:"We think that changing the color of the call-to-action button will increase the click-through rate because it will attract more attention." Clear hypotheses based on customer feedback will guide your tests.

‍

Select the variables to be tested

‍

Based on your objectives, hypotheses and identified pain point, choose the specific elements of the page you want to test.

‍

This can include titles, images, CTAs or layout. Be sure to test one variable at a time for clear results.

‍

Create alternative versions

‍

Create one or more alternative versions of your page or element, modifying only the selected variables.Β 

‍

This ensures that modifications are sufficiently distinct to potentially influence user behavior.

‍

Dividing traffic evenly

‍

Are your pages ready? πŸ™Œ

‍

The distribution of traffic between the different versions of the page to be tested will enable you to launch the test.Β 

‍

Use an AB testing tool to divide the traffic equally between the different versions. Each version should be presented to a representative and sufficiently large sample of your audience to obtain statistically significant results.

‍

Performance monitoring

‍

As soon as you launch your experimental pages, keep a close eye on the performance of each version. Make sure that each page receives traffic, functions correctly and doesn't need to be corrected.

‍

Use analysis tools to monitor the key indicators defined in the first step. Make sure the test duration is long enough to compensate for temporary variations and obtain reliable results.

‍

Analyze data to improve the page

‍

Your AB test campaign is over πŸ’ͺ

‍

Now collect performance data for each version. Analyze the results to determine the best version and apply the findings to optimize your site.Β 

‍

Repeat the process to ensure continuous improvements for new visitors and loyal customers.

‍

Implement and Iterate

‍

Finally, you have analyzed the results of your AB test experiments.

‍

Implement the winning version across your entire site or campaign. But the process doesn't stop there.Β 

‍

Keep iterating and regularly testing new hypotheses for continuous improvement. Optimization through AB testing is a cyclical process that needs to be integrated into your marketing strategy on an ongoing basis.

5. Best practices in AB Testing

To maximize the benefits of AB testing, it's crucial to follow certain tried-and-tested practices 🌟

‍

These recommendations will help you to obtain reliable results and draw relevant conclusions for the ongoing optimization of your site.

‍

best-practices-AB-testing

Testing one variable at a time

‍

In theory, to obtain clear and precise results, it's advisable to test just one variable at a time, such as the title, image or action button, to determine its exact impact on performance.Β 

‍

Testing several elements simultaneously can make it difficult to identify what really influenced the results.

‍

Because good methodological intentions are not always the most profitable, nor the quickest to achieve satisfactory results, our technology Dataiads applies a hybrid approach.

‍

At DataΓ―ads, based on our experience in supporting over 200 e-commerce brands, we like to start by testing strategies, which may themselves include several variables.Β 

‍

With this approach, performance increments are quickly significant, and strategic marketing lessons are quickly learned.Β 

‍

Once a significant impact has been achieved, we then refine the adjustments variable by variable on the basis of the analytical results obtained.

‍

To better understand this method, we recommend you read this article.

‍

‍

Ensure the statistical validity of the sample

‍

Launching an AB test means proposing an experiment to a part of the audience, or sometimes to all of it. In fact, it's interesting to target the population for a specific test.

‍

However, it should be borne in mind that too small a sample size can lead to insignificant and misleading results.Β 

‍

To be precise, use a sufficient sample size to ensure that the results are statistically significant and reliable. You can use sample size calculation tools to determine the minimum number of participants required.

‍

Have an adequate test period

‍

AB testing is generally carried out over a specific, even short, period of time.

‍

Nevertheless, it's important to give your test enough time to capture natural variations in user behavior.Β 

‍

Too short a duration may not provide a complete picture, especially if your traffic fluctuates according to factors such as the day of the week or current promotions.

‍

Analyze data rigorously

‍

Once the test is complete, it's important to analyze the results carefully πŸ‘€

‍

Take the time to decipher the results and challenge them!

‍

Use statistical methods to confirm the significance of the differences observed.

Β 

Don't rely solely on apparent variations, and make sure the results are statistically valid before drawing conclusions.

‍

Document and iterate

‍

Last but not least, AB testing is an excellent way of setting up continuous progression.

‍

To do this, record the results of each test, draw conclusions and implement improvements.Β 

‍

Repeat the process with new tests for continuous, progressive optimization.
