As Shopify Conversion Rate Optimization experts, we are passionate about optimizing every part of your customer's journey. We focus on making data-driven improvements that really move your metrics. Making guesses about user behavior can lead to the wrong decisions. To be sure that your ideas and changes are working, it's important to test them. A/B tests will give you real proof of what works and what doesn't. By testing your ideas regularly, you can make better decisions, improve user experience, and get better results for your business.
What is An A/B Test?
An A/B test is a method of testing different content variants or an element to see which performs better. These variants are shown to similarly-sized audiences, commonly an equal split between the variants for example, a 50% split between two variants.
An example of an A/B test could be alternating the background colour of the Add to Cart button on the product page:
|
Original Shown to 50% of users |
Variant Shown to 50% of users |
 |
 |
Once the test is finished, the data can then be used to determine whether changes should be made permanently to the site based on the results.
How long should you run an A/B test?
An A/B test must be run for long enough to gather sufficient data and see a clear difference between the variants. You want the test to run until it reaches statistical significance. Google recommends that an A/B test is run for a minimum of two weeks or until a clear winner is found. VWO offers a great online calculator that you can use to check how long you should run a test based on various factors, including what you want to achieve, how many variants you’ll be creating and what the traffic on your site looks like.
Are A/B tests worth it?
The simple answer is yes. Without testing your hypothesis, you're making a guess at what may or may not improve your site. By implementing an A/B Test, you can make data-driven decisions to ensure that you're optimizing your Shopify store (and your metrics).
A/B tests are considered low cost and high in reward; therefore, there isn’t much risk. It’s good, however, to set some targets of what you want to get out of the test before running it. Here are some examples of what targets to set and what you could achieve by running A/B tests:
- Increase conversion rate
Example: You want to increase conversions by finding the most optimal background colour of the product page and add to cart button. You could test two different background colours of the button to see which variant leads to more products being added to users' carts. By assessing the data and making the necessary changes to your store, will potentially lead to increased conversions
- Reduced bounce rate
Example: You want to reduce the bounce rate on your homepage by finding the most optimal position for your featured collection section. You could test two different positions on the page for this section to see which variant most engages your users. Finding the most engaging place for this section will potentially reduce the bounce rate on your homepage.
Why should I Run an A/B test?
By running A/B tests on your site and gathering insightful data, you’re constantly optimising the experience for your users and making it easier for them to shop. This will lead to higher customer satisfaction and (what most merchants hope for) a potential increase of orders on your store.
When should you not use an A/B test?
There are some instances where A/B Testing is not advisable, and sometimes they can be a waste of time. You'll need to ensure that you have a hypothesis before you decide to test, don't look at too many metrics and make sure you learn from previous failed tests.
A/B tests rely heavily on your store getting a lot of traffic. If this is low, it may be more worth your while concentrating your efforts on attracting more customers. If you’ve already run a test and want to check whether it’s worth making changes to your site based on the results, you can use an online calculator to test the statistical significance of your test.
