There are times when I used to get some descent earnings per click but there are times when I get very low CTR for adsense ad units.Is there any relation between the Total Number of adsense ad units per page to the CTR of each ad unit.I mean I used to have 3 'large rectangle ads' with 2 link ads in my previous blog.In my new blog i have only one large rectangle and one link ad.Is there any chance that my CTR would increase because of low number of ads per page.Any help is appreciated.
Yes, but you ads much look same as your site is. Am earnings 50% more after i understood it and applied it.
