I recently started using Adsense for the first time on one of my sites. When I did the keyword research, the average advertiser costs were between $9-12 for the main keywords. . so my thinking was that I would at least get 40-50% of that per click through adsense.
However, I seem to only be getting $0.20-.30 a click- very low. I am wondering if anyone knows of or uses any strategy or optimization that can be used to ensure that only the highest paying advertisers show up on my adsense ads on my site.
