I want to load up a list of keywords into a tool and have it count the number of Adwords for each keyword. Anything out there that does this?
Forgot how to do it but you can limit a search to show ads only. If you can do that through the API you can fetch the total (or illegally scrape it without the API - not a recommendation).
I'm not really sure what you';re trying to do; develop key phrases stemmed from a primary term? What do you mean by 'number of AdWords for each keyword"? OK, i re-read TOPS post an gathered that you're looking to figure out how many ads there are running against a key phrase. It's probably not the easier or most efficient, but if you customize your Google results to show 100 instead of ten, that's usually enough to list all the AdWords ads as well. If you have an AdSense account, you could use the AdSense Search to see as well, though make usre you don't click on any of the results!
Adword Analyzer will tell you how many ads are running for a particular keyword or phrase. You can only enter 1 at a time though.
