Hi All, I noticed a quite big drop in eCPM (50%) on my sites during the last weeks and I'm wondering, if there is a reason for it. Basically I doubt it could be related with the sites themselves, because I changed nothing. Also, I'm not using AdWords, so I doubt that a "landing page quality check" might give a reason for these changes. Maybe you encountered something similar and can give me a clue? For me, there might be 3 main reasons: 1) Advertisers are displaying less paied ads at the moment 2) Hot Summer time (germany +36deg. celsius upwards since two weeks) 3) Main public holiday time (what advertisers might lead to 1) Do you share my thoughts or are there other reasons I have to worry about? Also there has been a decrease in CTR by 30% during the last 14 days... The same value also has been for PageImpressions. If it would just be lower SERP for the decrease in PI, I'd guess it should not affect CTR in any way... The last point I can track ist that i receive just about 50% of SE redirects to my site since the last two weeks. This also can point to 1), 2) or 3)... Any guesses from the community? Cheers Emrys
