Dear forum members, I have analyzed the stats for several of my sites with both Google Analytics (Traffic) and Google Webmaster Tools (Impressions). However, I have noticed that there is no correlation of these two statistics. How come? I guess that both tools should base on the same or similar databases and/or sources. So, I would expect at least a bit of correlation between these figures. Most obvious, the deviation becomes with peaks in the impressions in the webmaster tools. While I can see improvements of up to 500% in impressions, there is no significant change in the traffic data in Analytics. Can anybody explain this phenomenon?
