Freesource Notes:	Google’s Keyword Tool lets you submit one keyword or phrase to see what related word searches your ad will show on. You can use the Keyword Tool to get new keyword ideas and it’s a great way to find new keywords for your ad campaigns and SEO efforts. The results provide some exciting data on keyword search statistics, similar words & phrases and their statistics. If you play with this, I’d recommend visiting the “Keyword Tool Tips” page for some ideas and advice. And like most things Google, the Keyword Tool is entirely free.
