automatic distributed by my content management system in the navigation area. It depends on the free space in the menus. The system tries to place
300x250 and 160x90 as the maximum. If not enough place, smaller ads are selected.
In the content area, at maybe 5% of the pages are additional
120x600
250x250 used.
I would say that it's always worth experimenting with different placements. I've recently re-introduced banners on pages where Adsense previously didn't work by putting the banners in different places to where they previously were. I personally like my site to be pretty much uniform in page layout, but varying the placement seems to have worked on some pages.
It's worth experimenting over time to see what works for you.
Currently experimenting with blending ads completely into the site opposed to having different borders and background colors and such, seems to also be increasing CTR and eCPM and I'm only half done with this project.
