Why does this happen?
Have you ever noticed a "flicker" between the control and variant pages? What you are experiencing is what is referred to as a flicker. You will see the control and then see it quickly change to the variant. This occurs when a site takes a little longer to load.
How to Resolve this Situation
INSTALLING THE A/B TESTING SCRIPT PROPERLY
- Directly install the code snippet from your A/B testing tool into the header of your site. Please do not use a tag manager, which will cause content flickering.
- Install the script from your A/B testing tool inside the <head> element of the pages on your website. This will ensure that the script is loaded first and prevents flickers.
- Reduce the size of the code snippet by removing any inactive tests.
OPTIMIZE THE LOADING TIME OF YOUR TESTING PAGES
- Use a content delivery network (CDN) to make loading the testing page fast.
- Optimize and compress the images on your page - use PNG format where possible.
