Nelio A/B Testing and Google Analytics have different tracking methods, which means you may find differences in the number of visitors tracked from these tools. The following are some of the most commonly reported issues and their reasons:
How to differentiate variants in Google Analytics
https://example.com/tested-page/ will become
https://example.com/tested-page/?nab=x (where x is the variant the user is supposed to see; 0 is the control version, 1 is version B, and so on).
https://example.com/tested-page/?nab=x, this one will, and that’s the URL Google Analytics will track. Therefore, you’ll be able to tell apart from one variant from the other by looking at the
nab query arg.
However, note that it is possible to ignore the
nab parameter in Google Analytics.
“Pageviews” data in Google Analytics and “(Tested) Page Views” in Nelio A/B Testing give different results
Pageviews data in Google Analytics is the total number of visits on the website. Google Analytics tracks all visits to a page (both first-time visitors as well as returning users).
(Tested) page views in Nelio A/B Testing also implement this approach: they count both first-time and returning visitors. However, not all visitors accessing a certain page are counted by Nelio A/B Testing. Only those visitors that participate in the test will be included in the results. Visitors may be excluded from an experiment if you limited the percentage of users that may participate in your tests.
