We have identified an intermittent issue that affects the accuracy of event-tracking for redirect experiments in Optimizely X Web. If your experiment is affected by this condition, redirected visitors may be under-counted on your Results page.
Fixing this issue is a top priority for our engineering team and we apologize for any inconvenience this may cause. Please read on for how your experiments may be affected and what your options are.
How does this affect me?
The condition may result in under-reported metrics on the Results page of the redirect experiment. Specifically, this issue may cause visitors and events to be under-counted on the redirected page.
Here's a summary of the issue:
The Optimizely Results page may under-count visitors for the redirect experiment if the redirect URL is on a different protocol (http versus https) or domain than the original page.
All third-party analytics integrations (Adobe, Google, Clicktale) used with redirect experiments may under count visitors, regardless of the protocol or domain.
If your redirect experiment falls into one or both of the categories above, you may experience under-reported results for that experiment.
How do I know if my experiment is affected?
Here are signs that your experiment may be affected:
The Optimizely Results page shows fewer visitors in the redirect variation compared to the original variation -- and the difference between original and redirect variation visitor counts is greater than 10-15%.
Results in your third-party analytics tool show fewer visitors in the redirect variation compared to the original variation -- and the difference between original and redirect variation visitor counts is greater than 10-15%.
If you have questions about this issue with redirect experiments, please reach out to Optimizely support.
Options for running a redirect experiment
These are near-term options for running a redirect experiment.
The issue described above does not affect Optimizely results or tracking for same origin redirects on the Optimizely results page. You can still run a redirect experiment in Optimizely X if the original and redirect pages are on the same origin.
To learn more about origins, checkout this article.
If you want to use a third-party integration for a redirect experiment, where the redirected page is on the same origin as the original page, there is a workaround:
Create a page in Optimizely X based on the URL that you are redirecting to.
Add the new page to the experiment.
If you need to run a redirect experiment across origins, we recommend using the redirect feature in Optimizely Classic.
