do I just type tye url into google and the number of searches that comes back means those are backlinks?
You use the link: command add your URL after link: Use Yahoo to check your backlinks they keep a better record.
The link:yourdomain command in Google is very inaccurate and shows too low a number. Here are two good ways to check your backlinks more accurately. You will need to open a free account at each one, if you don't yet have one: • Google Webmaster Tools (you can Google it to find the url) • Yahoo Site Explorer (also free; you'll need an account)
