A/B testing (sometimes called “split testing”) is a method of running optimization tests on your site. To run an A/B test, you create 2 different versions of a web page that differ in 1 way — such as having different calls-to-action (CTAs). Then, split site traffic between the 2 versions and compare chosen metrics from each to determine which version (A or B) produces better results. It’s important that you only change 1 element of variant B. Otherwise, you won’t know which change led to better performance.
Before you get started: If you haven’t already, create an Optimizely account and copy your Optimizely script.
Your Optimizely script should look something like this:
To add Optimizely to your site:
- Go to Site settings > Custom code tab
- Paste your Optimizely script in the Head code section
- Click Save changes
- Publish your site
Then, go back to your Optimizely dashboard and create your first A/B test. Your Optimizely dashboard will monitor performance and show you how each variant performs.
