How to Plan Your A/B Test

A question we hear all the time:

When Should I Start Testing?

The answer: Once you've starting receiving data that lets you come up with ideas of what to improve. 

Whether you have 5 visitors per month to your site or 5,000, if any of those visitors are not converting, you should be finding out why and testing ideas. A missed conversion is a missed opportunity. Testing out ideas to improve your visitor experience is a surefire way of building lasting relationships and more opportunities.

Once you've looked at your Snapshot Reports and watched your visitor Recordings so you have ideas for what to test, it's time to get planning.

Planning Your AB Test

Planning your AB Test doesn't have to be a challenge. Here at Crazy Egg we developed an AB Test that makes it fast and easy to test ideas that will help you improve your user experience. We do this by using the Multi-Armed Bandit approach to A/B testing so that you can maximize your ROI. The value of our approach is that you can continue experimenting with different variants by changing copy, images, and calls-to-action, and always be assured that your website traffic will be directed to the highest converting version of your web page. 

While Crazy Egg automates the A/B testing process, it's key to plan out what you want to test before you launch a variant. Figure out your goals like increasing signups for a particular event, boosting trials of your software, sending increased traffic to specific pages, and/or selling more of your product. While our A/B testing tool allows you to iterate quickly, you can be even more targeted with your time by creating a hypothesis on how changing different elements will impact your conversion rate. 


Where Should I Start?

Start with what you know. Look at your Snapshot reports for the page you want to improve your visitors experience on.  Ask yourself where are people hesitating, why are they moving past my CTA, how can I engage them more?

Sample Scenario

Let's say you're offering a limited-time deal and you want to maximize your conversions for a time period. In this instance, you could experiment with the copy on a large call-to-action button on your page. 

Control copy:

Join our mailing list and receive 25% off your first purchase.

Variant 1:

TAKE ADVANTAGE OF TODAY'S EXCLUSIVE OFFER! 
Join our mailing list to receive 25% off, plus other perks delivered straight to your inbox.

The new copy holds the potential to create a sense of urgency and may be a key factor in causing a spike in signups.  You can test this idea and goal, by creating a variant and pitting it against your original copy.  This is the type of planning you need to do.
