For over a month now, I have been unable to rely on the official WordPress Stats plugin. (I say official because the folks that made WordPress also made this plugin.) It, all of a sudden, started assigning all site visits to the same article, so that all of my stats became completely skewed. Let me explain it with a screenshot:
Instead of seeing the proper distribution of site visits by titles, which is what happened in the past, almost all of the site visits get assigned to a random post. I have no idea any more which titles get the most traffic for a given day. I know this is wrong because I’m also using Google Analytics. Here’s a screenshot of the 20 most popular titles for the past 30 days.
I like WordPress Stats because they aggregate the data almost instantly, whereas there’s a 3-4 hour delay with Google Analytics. Sometimes they even correct the data a day afterward (this happened to me recently) so you can’t rely on their figures until 24-36 hours after the fact [reference].
I stopped using WordPress Stats for a while, hoping the problem would somehow work itself out, but when I re-activated the plugin, all that happened is that it started assigning all site visits to a different random post. Whoopee…
If someone at WordPress reads this, please let me know if it’s something I’m doing wrong, or if it’s something that you’ve got to work out on your end. I posted about this problem in the WordPress forums, but I have yet to receive a reply there.
