To find out what Google thinks about your website, perform a “similar” search for your domain. Enter the following in Google’s search box:
related:www.domain.com/ ~domain.com
Replace domain.com with your own domain name and make sure that there is no spacer after the colon. On the result page, Google will show you websites that it finds related to your site. If the websites on the search result page are related to your website then everything is okay. If the websites are about totally different topics, then you have a problem and Google probably won’t display your website in the search results for the right keywords.
Nice, this may also a good way to find related sites if you do ppc/media buys.
