If you've been reading my blog, you know how much I love to share really great Internet tools - especially when they're free. Check out this tool at SEODigger.com What's so great about this tool is that it detects search keywords for which a site is ranked high. This takes a lot of guesswork out of which keywords (on Google) generate search results containing your URL.
It's easier to explain if you simply visit the site and try it yourself! Just visit SEO Digger and type in your URL. The result shows which keywords you're site is ranked high for on Google and the relative value of those keywords based on Overture results... very cool!
