Today, we’re going to dive into the wonderful world of A/B testing for ecommerce websites. Now, I know what you’re thinking – “A B testing? That sounds like a fancy, complicated process that only data scientists and statisticians can understand.” But fear not readers! A/B testing is actually a simple and effective way to improve your website’s performance and increase sales.

Let’s begin by defining what A-B testing is. A/B testing is a process that compares two iterations of a website or app screen to see which one works better. You can learn which version generates the most clicks, conversions, and eventually sales by showing one version at random to one group of visitors and the other version to a different group of visitors.

Now, you may be thinking, “But my website is already pretty great! Do I really need to do A/B testing?” The answer is a resounding yes! Even small changes can have a big impact on user behaviour. For example, changing the contrast of a button to make it stand out from the background could increase click-through rates by as much as 21%. That’s a significant difference!

How then do you carry out an A/B test? The basic stages are as follows:

  • Determine the issue or opportunity: What particular problem are you attempting to fix or enhance on your website? Perhaps you want to encourage more customers to add products to their shopping carts, or perhaps you want to streamline the checkout process.
  • Create a hypothesis about what change might produce better results based on the opportunity or problem you’ve found. For instance, you might propose that streamlining the checkout procedure will increase the number of completed purchases.
  • Create multiple versions of your webpage: Develop two versions (a/b) or multiple versions (a/b/n) of your webpage that are identical except for the one element you’re testing. For example, you might create two versions of your checkout page – single page checkout vs. multi step checkout.
  • Randomly assign visitors: Visitors to your website will be randomly assigned to either Version A or Version B. A/B testing software can be used for this, automatically distributing your traffic equally between the two variants.
  • Collect data: Gather metrics on how visitors engage with each version of your website. Data points like click-through rates, bounce rates, time on website, and completed sales may be included dependant on your hypothesis.
  • Analyse the results: Once you’ve collected enough data, analyse the results to determine which version performed better. If version B (the simpler single page checkout) led to more completed purchases, then you can confidently implement that change on your website.

Now, I know what you’re thinking – “But wait, what about all the other variables that could be affecting user behaviour? What if people just happened to be in a better mood when they visited version B becuase the sun was shining?” Good question! That’s why it’s important to conduct your A/B test over a significant period of time (at least a few weeks) and with a large enough sample size to ensure that your results are statistically significant.

So, there you have it – a quick and dirty guide to A/B testing for ecommerce websites. Remember, even small changes can have a big impact on user behaviour, so don’t be afraid to experiment and test different versions of your website. Who knows, you might just stumble upon a change that leads to a huge boost in sales. If you do, please share in the comments below. Happy testing!
