Is there a limit to the number of searches that anyone knows of? I can't get a clear response (i.e. an answer that doesn't beat around the non-disclosure bush) from the support team.
You don't want to use Googles keyword suggestions tool...
I just wanted to jump in with a small but important distinction:
The keyword tool that AdWords offers is not actually called a Keyword Suggestion tool, nor is it intended to be one.
Rather, it's intended to provide a jumping off point as you build your keyword lists. Many of the keywords it returns, for example, may serve you far better as negative keywords.
It's essentially intended to give you a list of words related to the word(s) you've plugged in, about which you'll then want to make informed decisions, based on your knowledge of your business, product, market, customers, etc.
