Back in “good old days” the WPP 30 days showed the same numbers that GA did show
That’s because after 2.3.2 -I think, it’s been a long time- the way WPP updated views count changed from AJAX (Javascript) to template detection (check if single.php was loaded).
Since most spiders / bots out there can’t run Javascript (which is something I wasn’t aware of back then), versions prior 2.3.2 successfully filtered out their page views because the AJAX call was never executed. This is why the statistics would be close to what GA reported. After that change though, WPP started counting their page views as valid ones, inflating the statistics.
Of course, I wouldn’t have made that modification if I knew that. Unfortunately, a long time had passed before I realized what the problem was. WPP 3.0.0 could have been released months ago actually, but I decided to spend a little more improving the plugin and making sure old bugs were fixed for good.
Anyways, this is why the statistics were not that accurate. Unfortunately, what WPP has registered prior to 3.0.0 can’t be corrected so old stats (weekly, monthly, all-time) will still reflect visits from bots.
In your case, however, something’s odd. There should be more visits on WPP than on GA. You’re reporting that GA is actually displaying more views than WPP does. Are/were you using a caching plugin, by any chance?
A long post, I know. If you actually read all that, thank you for your patience hehe.
