Once you've already identified the pages you want to focus on, and the Snapshots are all set up, it's worthwhile comparing metrics to discover new opportunities for optimization and to cross-check your data. When pulling your data from Google Analytics to compare with Crazy Egg, you will want to make sure there are as many similar factors as possible. For example, check if you are looking at the same URL/page and that you have filtered your data by the device traffic type ( second dimension reporting) specified in your Snapshot. You also want to be sure to choose the same start date as the first date your Snapshot tracked a visit.
From here, you'll want to look at Pageviews rather than Unique Pageviews in Google Analytics. While the numbers between the platforms won't fully match up, since Google Analytics uses a slightly different (guarded) algorithm, the figures should be close. Your pageviews' similarity will also depend on your Snapshot settings and if you have reached your pageviews quota before the month is over.
With these two powerful tools at your disposal, you're much better situated in your quest to design a better visitor experience on your site!
Impact of GDPR on Volume Tracking
If this tracking suppression has not been set up correctly, such as suppressing only one script (for example, Crazy Egg and not Google Analytics), or your website suppresses tracking regardless of visitors accepting cookies, then you will see lower volumes of tracked visitors and even a data discrepancy between the two platforms.
