- No Google ad may be placed on any non-content-based pages.
- No Google ad may be placed on pages published specifically for the purpose of showing ads, whether or not the page content is relevant.
So it's likely that some arbi sites are breaking these rules... but that's not to say "arbitrage" as a whole is not allowed. As Graywolf pointed out in his blog recently, About.com is almost pure MFA (Made For AdSense) junk, and yet it gets millions in revenue.
Arbitrage happens in every market where there are inefficiencies in the economic process.
It's been going on for thousands of years in various markets. Search is no different.
Do I need to worry about the bots scanning my page? If so why?
