this month my CTR decrease but I did not change my blog layout.. please help to review again my blog to see if there any bad GA placement (I already ask dp members before and they say the ads placement was nice.. but I need more review because of dropping CTR problem) thank you in advance for your kind assistance Darin My blog is in my signature
Well, first referrals did not work well for me. Second, try to move the right column ads to the middle of your content and see the results.
I'd say the dropping CTR is likely due to returning visitors - they're becoming more and more "ad blind" every time they visit the site. A good way to tackle this is to have four different color variations for each ad unit (this is achievable when setting up the ad unit). Make sure the colors stand out too.
a helping hand: thanks for your suggest, referrals also not working with me, maybe I just remove it from my blog. ponynugget: again, thanks for your advise, I'll try to change the color.. thanks for all of you! hopefully this tips will help me increasing my CTR
