It's probably just my site but was wondering if anyone else had been noticing a major drop in adsense revenue over the last week. I used to make around $40-60 just from page impressions, not clicks, but as of Monday it just disappeared over night. I have high quality content and am in the top ten for many of my keywords, just wondered if this was a) just my site b) a drop in summer ad revenue 3) something else entirely. Mt visitor numbers haven't changed and I have no problems with my adsense account and I'm not involved in an black hat stuff, just good backlinking strategies Anyone got any ideas?
