Google Analytics shows a high number of visitors, Optimizely has almost 0. Why?
I have a similar issue. Since yesterday GA shows really high numbers but Optimizely shows only 4 visitors.
I have set up an experiment on the home page. The numbers I am looking at in GA is Sessions, Under behaviour tab - /index page views and /home index page views.
Please let me know what I am doing wrong.
Also, did the results look correct originally and this just was an issue yesterday? Or has this been an issue since the experiment started?
Targeting seems correct - All visitors , 100% traffic included
Confirmed snippet is installed correctly
I don not understand what you mean by URL targeting the same as the view?
Optimizely may be counting visitors differently to how GA counts them, which is explained in this section of our article, here. But more than this, it could be the data you're looking at - Optimizely will only count a single user once over the lifetime of the experiment, but for instance this article explains that a "unique pageview...aggregates pageviews that are generated by the same user during the same session." You can read more on google's support article, here. Would you be able to confirm with me which metric you’re using in your web analytics tool you’re using?
What Amanda was referring to is to make sure the URL targeting of your experiment (lets say, the home page only) matches those pages covered in your GA report, and you need to align the dates and times (in Optimizely's results page, you can filter the page to 'custom' in the top left hand corner). You will also need to align the visitors - if you could use unique visitors as opposed to sessions (this will reset every 30 minutes of inactivity, or if a tab closes) or any other metric.
I hope that helps!
