Does Google allow embedding an iframe into a page containing the Adsense ads, as a pose to placing them straight on the page? I have a problem, because I have two websites: One which earns anywhere around $1 a click, and the second which earns anywhere up to $0.10. Also, I'm quite sure I would get a lot more clicks if I could display the ads from the first website on the second. Any info would be great, thanks.
If you embedded the ads in a framed page, how would Adsense know what ads to serve? AdSense places ads on a web page based on the content of that page. It sounds like the ads relevant to the content of your first page are higher paying than on the second page. If the ads and the content are not on the same page - if the ads are in a frame or the content is in a frame, AdSense can't tell what ads to serve and you may end up with PSAs. See this page from Google: http://www.google.com/support/adsense/bin/answer.py?answer=43998
yes, there is even an option on the ad code page to select if the ad is in a framed page so it checks the source page for the content. (at least there used to be)
In the rest of your iframe you could place some high-paying keywords. But that would be against their TOS, so don't do it.
