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.
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.
