So I have a site that about a year ago had a CTR of over 10% with the old clickbump theme when it was top 3. Long story short I let it slip to the second page. I have been working on it, and got it back to #3 but the CTR with ad$ense is only 2.5% now. I know its the old clickbump theme but I cant figure out why last year the CTR was so much better. Anybody have suggestions? Would love to try some good themes for CTR and have a spot for aff offer on the side.
