regarding the images - i think we need a border either around the ads in order to do that? or around the image, or a line separating the images from the ads.
can you let me know the exact url of your website, so that i will look at the project practically. Are you sure that all above tiips do not break any adsense TOS?
good tips.... but i request u to stay away from point no.8 caues if google is offended then u know what happens.....
Tracking can tell you which pages are doing better. You can also vary things like placement, formats and colors and track the results of your changes over time. Good tips...
