Ok let’s take yesterday statitics on my wife’s new blog : Mademoiselle prend soin d’elle
Piwik gives me : 44 visitors, 39 unique visitors
Google gives me : 80 visitors, 71 unique visitors
About Piwik, i use the plugin WP-Piwik for wordpress, that will insert in the footer of the page the script. I checked the insert of the script, the following of 404 errors and the use of js/index.php. I excluded my home macbook, my office PC and request the plugin to not track Administrators of the blog.
About Google, i use SEO plugin that will also add the tracking script in the footer and requested to not track Administrators of the blog.
What i find very very strange is that google seems to add “phantoms” visitors. For example yesterday, around 8pm, we saw on google a visitor with IP address 192.168.1.10:8888, wich is usually me when i have to test things in local for the site. But yesterday i did not started at all my MAMP application. And my wife, despite she is administrator, she is detected as a google searcher with keywords used 1 week ago …
Despite these differences, the difference between Google and Piwik is quite huge for my opinion. Who can i trust ?
I would prefer piwik with google number of visitors >:D<
