I have an image site with a lot of galleries. The images have always done well in Google image search and account for half of my traffic now. On the 12th of June I removed Google Adsense from my galleries. Google Analytics in WMT is showing a very noticeable change in pattern after the 26th of June. For some search terms there is a drop in position whilst showing a large increase in impressions which gives a much lower click through rate. With some keywords the opposite has been observed. The number of clicks for some terms is down a bit but the impact varies depending on the keywords. There has been about a 10% to 20% drop in traffic to my site overall.
Is it just me, or have others also noticed a change occurring after the 26th June?
