SEOmoz has released a new tool call Open Site Explorer to help you analyse links to your sites. Rand has a full write up on it on the SEOmoz blog.

It’s based on their Linkscape data, and similar to Yahoo Site Explorer in many ways (but a lot easier to use).

Simply plug in the URL you wish to analyse (or compare with – you can enter multiple URLs) and push the button.

Open Site Explorer

The site will return link data about your domain, along with ratings on page authority and domain authority. Here’s a quick summary based on my personal site.

If you’re a Pro Member on SEOmoz and use their toolbar you’ll notice these domain totals match the details there:

Open Site Explorer is a handy tool for checking backlinks on both your own sites, and those of competitors.
