My CTR is only at about .6% on a good day. My ads are placed appropriately. I couldn't figure out why. So I decided to look at clicks/visit instead of clicks/impression. The result came out to be about 5% of my visitors click on my ads at least once which is way better than my CTR. My site has a ton of content and users view 9 pages per visit. I think my users would rather stay on my site than to leave by clicking on an ad too soon. What is your clicks/visit?
