I have a health and fitness website with adsense and generally I earn £0.01 per ad units click (skyscrapper and medium rectangle) and earn over £0.25 on link unit clicks why is that???? sometimes I earn £0 per ad unit click yesterday I got 6 clicks and only earned £0.06 today I got 1 link unit click and earned £0.43 why is that????
It depends on a lot of factors. one is the country the person is clicking from... depends what advertisers are willing to pay per click in that country.
