How can I tell what sites have links to (inbound links) to my site?
There are two ways to do this. You can open Google and type link:www.yourdomain.com in the search box. This will show you all the site that link to the www.yourdomain.com site (use your own domain of course).

You can also get here by going to the Advanced Search page on Google, here:
http://www.google.com/advanced_search?hl=en

Look for the search option that says:
Links Find pages that link to the page

To the right of this text there is a search box and a Search button. Enter your domain name here and click this Search button.
