I've been wondering how websites like SpyFu work...
I know they aren't really getting the keywords from other sites' accounts, because I've tested their service and others against sites that I control the AdWords campaigns for. But they come pretty close in some cases.
Is it just a matter of constantly querying google's ad preview tool with different search terms and scraping the sponsored results? That seems like an arcane method that would get you in deep shit with the big G pretty fast, but I can't think of how else they're doing it. Perhaps using the AdWords API?
I'd settle for educated guesses, I'm just curious about how they build these tools.
