Knowing who's linking to your site, not to mention your competitors, is an important part of SEO. The link analyzer allows you to do this with a single click.

After entering in the url of any page on any site on the web, you can view the links pointing to and from the page, including internal links. The most obvious way to use the tool is to find out who's talking about you on the web, and giving you a boost in the search engines in the process.

Another way to use the tool, however, is to find out who's linking to your competitors. This is very useful, because it allows you to determine why they rank so well. It's also a gold mine for your own link building. By sifting through your competitor's links, you can find places to build some of your own links.

As part of a broader strategy, you can also figure out what kind of competitor you are dealing with. It shouldn't take long to determine whether the links are being created by the competitor themselves, or if they are using link baiting techniques instead.

Once you know what kind of competitor you are dealing with, and where there links are coming from, you'll be able to develop a strategy to compete with them, or avoid wasting your time on a keyword that's too difficult to rank for.
