When it comes to eCommerce, customer experience is everything. According to Statista, 44% of businesses worldwide perceive customer experience as their primary competitive differentiator.

An eCommerce store is only successful when it creates a quality user experience through constant innovation and testing out what attracts your customers the most. For this, you should have tangible insights into what your target audience actually is. And that is achieved by A/B testing.


What is A/B testing?


An A/B test is a process of showing two variants of an element on a site, displaying it to two different segments of the audience, and measuring the conversion rates of each. It is used to determine which variant is more effective in achieving the desired outcome.


A/B testing is an important tool for improving the performance of your marketing campaigns and answering important business questions like what helps in generating more revenue from the traffic you already have and how to tweak your current eCommerce website to improve conversions.


Steps to perform A/B test?


Define the overall goal of the A/B test


Chose which metric to monitor so you know what to analyze for success or failure. It can be done by analyzing which area of your site you would most like to improve.


Record your site’s current performance


Before you make any changes to your site, record your site’s existing metrics. Noting these metrics beforehand will give you a clear idea of how effective the winning variable was.


Identify which items you want to test


Choose a variable to test that will help you achieve your chosen goal. Some of the most used variables in eCommerce A/B tests include:

  • Headline
  • Body copy
  • CTAs
  • Forms
  • Site design
  • Navigation
  • SEO tactics (meta description, keyword density etc)

Set up two test variations:


Document the specific differences you will test and repeat the same variable across all pages for each variation. This will ensure that customers’ experience remains the same throughout the site.


Segment your audience


Plug all of your information into your A/B testing software and set the test to run. Most software evenly and randomly divides your test audience into A and B groups.


Test both versions A and B concurrently 


Run variable A for a certain amount of time and switch to variable B for the same amount of time.


Analyze the results


Most testing tools clearly spell out which variation was the more successful of the two. Analysis of more granular data was provided to get a clearer picture.


Pay attention to statistical data


Testing platforms automatically account for the variance using statistical calculations. When looking at statistical significance, the output is typical:


A percentage that represents how solid the finding is.

A range of conversion rates is known as a ‘confidence interval’. It represents the range of conversion rates in a repeated sampling of your site visitors.
