What is AB testing? 5 best AB testing methods to discover

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

The The principle of AB Testing is based on the collection of concrete data, allowing businesses to make decisions based on performance.

Concretely, this method consists of comparing two versions of a web page or a campaign element to see which one gets the best results.

‍

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

This article introduces you to a A complete guide to AB testing. Definition, test types, test optimizations: let's look at the best practices together.

1. What is AB Testing?

Definition of AB Testing

‍

A/B Testing, also called split testing or A/B testing, is a scientific experimentation method used in digital marketing 🧑🔬

‍

Imagine comparing two versions of a web page or campaign item to see which one gets the best results. Each version is shown to a group of similar users. Performances are analyzed to determine which converts the most.

‍

The principle is based on the collection of statistical data. By using metrics like click through rate, add to cart, or conversion rate, businesses can make informed decisions based on real facts, rather than assumptions.

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

3. The different types of AB Tests

There are several types of AB tests that online retailers can Use to optimize their web pages and campaigns. Each type of test has its own advantages and can be adapted to suit specific business goals.

Simple A/B test, the most used version

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

‍

It involves Compare Two Versions of the Same Page or Item, called version A and version B.

‍

Users are randomly divided to see one of the two versions.

‍

The performance of each version is then compared based on key metrics such as conversion rate or click rate.

‍

The Multivariate Test, to test several variables

The Multivariate Test Goes One Step Further By testing multiple variables simultaneously. It is an opportunity to test several variables at the same time.

‍

This method Identify combinations of elements like the title, the images, the call to action button - or CTA- that have the biggest impact on overall performance.

‍

Multivariate AB tests make it possible to understand how these elements interact with each other.

‍

Redirection test, or the comparison of two separate pages

‍

Redirect testing, or split URL testing, is used to compare completely different web pages with each other.

‍

Unlike simple A/B testing that changes items on the same page, redirection testing sends users to completely separate URLs.

‍

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

‍

Real-time A/B testing

‍

Real-time A/B testing allows test changes live on a website without creating separate static versions.

‍

The changes are applied directly via an A/B testing tool and the performances are monitored in real time.

‍

This provides flexibility and speed of execution, ideal for quick adjustments and continuous optimizations.

‍

A/A and Multi-page Test

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

‍

Les multi-page tests analyze changes across multiple pages in the same conversion funnel to optimize the overall user experience.

4. How to carry out an effective AB test

To obtain significant results with AB testing, it is important to follow a rigorous methodology.

‍

We identified 8 key steps.

‍

Define clear goals

‍

The first step is to define the goals of your test.

‍

What do you want to improve? 🎯

‍

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

‍

Only well-defined goals will allow you to accurately measure the success of your tests.

‍

Formulate hypotheses

‍

Once the goals have been established, Formulate hypotheses to apply to your AB Test, on what you think you can improve and why.

‍

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

‍

Select the variables to be tested

‍

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

‍

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

‍

Create alternative versions

‍

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

‍

So, you make sure that the changes are sufficiently distinct to potentially influence user behavior.

‍

Divide traffic fairly

‍

Are your pages ready? 🙌

‍

La distribution of traffic between the different versions of the page to be tested will allow you to start the test.

‍

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

‍

Track Performances

‍

As soon as you launch your experiment pages, Closely Monitor the Performance of Each Release Of your ab tests. Make sure that each page gets traffic, works properly, and doesn't require corrections.

‍

Use analysis tools to Follow the Key Indicators Defined During the First Stage. Make sure the test time is long enough to compensate for temporary variations and get reliable results.

‍

Analyze data to improve the page

‍

Your AB test campaign is over 💪

‍

Now collect the Performance Data for Each Version. Analyze the results to determine the best version and apply the findings to optimize your site.

‍

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

‍

Implement and Iterate

‍

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

‍

Implement the winning version across your entire site or campaign. However, the process does not end there.

‍

Keep iterating and Test new hypotheses regularly for continuous improvement. Optimization with an AB testing solution is a cyclical process that must be continuously integrated into your marketing strategy.
