Google Analytics and QA Analytics use different data collection methods, so while they approximate the number of visits, they are rarely an exact match. In many cases, QA Analytics has smaller values.
(See “Difference between QA Analytics and Google Analytics” for detailed measurement specifications.)
However, if the values are very different, the measurement may not be working properly.
If the QA Analytics figures are low
If the number of visits is very different, especially if the numbers on the QA Analytics side are low, there is often a flaw in the measurement, especially a JavaScript error. (If there is no smartphone data, errors may be occurring when displaying on a smartphone.)

If the QA Analytics figures are unusually high
Due to a bug in PHP, there was a period of time when QA Analytics was not measuring correctly.
This is a bug that has been found especially in PHP 7.4. (We have also seen reports of it being found in earlier versions.) Please check your PHP version.
This bug has been addressed in version 3.2.0.0, and data measurement has been normalized.
If your plugin version is older than that, please update it. After updating, the data will be recorded correctly.
