Is it possible to use Google's adwords API to scrape keyword's in the Google keyword tool? I know Google doesn't permit scraping, but I just want to know is it possible. If yes, how do I get started?
I would have thought if Google does not permit it, they would not make it possible on their own sites. I don't know for a fact, but it would make sense
Yes, but the AdWords API is not free (you have to pay to use it): http://code.google.com/apis/adwords/v2009/docs/ratesheet.html
You may consider reading this but the answer will be the same. You would better not trying to game over them, especially about API stuff which is easily to tracking history and usage activities.
