- Troubleshoot experiments and campaigns in Optimizely Web Experimentation
We work hard to make Optimizely Web Experimentation delightful and seamless, but sometimes technology does not work the way you expect it to. For those less happy times, we created a few resources to empower you to troubleshoot your experiment or campaign.
The Preview tool helps you check the functionality of your experiments and campaigns, including how visual changes look for different audiences and when events fire.
Tools for QA
If things do not look right, here are a few more advanced resources to help you diagnose the issue:
-
The JavaScript API helps you verify what live experiments and campaigns are running on a page and which variation into which you are bucketed.
-
The network console helps you verify whether events in a live experiment or campaign are firing correctly. Use it to check that metrics are tracked correctly on your Results page.
-
The Optimizely Web Experimentation log helps you diagnose more difficult issues in a live experiment or campaign. It tells you whether an experiment or campaign activates on the page, whether you qualify for an audience condition, and whether changes on a page are applied.
-
You can also read more about how Optimizely Web Experimentation's cookies and localStorage uniquely identify visitors, track their actions, and deliver consistent experiences across page loads.
Common issues
Here are a few issues you may need to troubleshoot:
-
A metric is not tracking correctly – You might notice few or no conversions you check the Results page. This article on troubleshooting metrics is a good place to start.
-
Your page loads slowly, or you see flashing or flickering – In other words, your original content appears for a moment before the variation. Here is how to troubleshoot flashing content.
-
Your variation content does not appear on your live site – If you are not seeing the changes you expect, read this troubleshooting article.
-
You are not seeing a variation that you expect – Use the JavaScript API to check the variation into which you are bucketed or the log to see whether you qualify for the audience.
