Welcome to the Q&A Forum

Can anyone (not Google affliated) explain to me where Google's data really comes from in their Keyword Tool? Is it at all based on organic search? Or only on Google Ads related data? I know there was some controversy back in June '10 and the Google remedied the return of suggested keywords but I can't seem to get a clear answer (other than from the Google blog itself) whether the search volumes returned are truly indicative of organic search. Am I relying on the wrong tool? Do those more savvy than I only rely on the keyword tool for PPC research. Please help! I'm obsessing over my numbers here. 🙂
