If you like playing with cool SEO tools and like to keep up with how you are doing in the search engines for your keywords, then you should try SEODigger

If it tells you that your domain name is not in the database, it may be an error. I did searches on my own whenever it came up with that and found that the domain was in the database after all. So while no seo tool is perfect, this one is very good.

You have to sign up to be able to research up to 10 domain names in one hour, but it’s free and easy to signup.
