Yesterday we profiled the Google Adwords Keyword Tool, today we'll profile a new Google Keyword tool that was launched not long ago.

It's the Search-based Keyword Tool, it's still in beta, but delivers valuable information. First what is the difference between this keyword tool and the Adwords Keyword tool? Taken from the Google FAQ:

The main difference between the Search-based Keyword Tool and the Keyword Tool currently in AdWords is that the former generates keyword ideas based on your website, and identifies those currently not being used in your AdWords account. Additionally, the Search-based Keyword Tool provides more detailed data for each keyword, such as category information, suggested bid that may place the ad in the top three spots of a search results page, and ad/search share. Both tools, however, offer the option of browsing all keywords across all categories.

Also according to google the Search-based Keyword Tool generates keyword and landing page ideas highly relevant and specific to your website. In doing so, the tool helps you identify additional advertising opportunities that aren't currently being used in your AdWords ad campaigns.

All you need to do is enter your website URL and any words or phrases that you'd like to compare it against and it will produce a list of related keywords including the Monthly searches on Google for that keyword.
