Links are very important for websites. Especially in Google, links back to your site help establish you are respectable, and are a key to your rankings and PageRank.

So it’s good to know you can go through Google, and find rankings easily. Here’s a couple of ways to search on Google for information (replace with your site, of course):

link:www.bigbizblog.com
  -or-
link:bigbizblog .com

Shows links to your site – with and without the ‘www’ affects the count, since each is considered a seperate URL.

bigbizblog.com -site:www.bigbizblog.com

(the ‘-site:’ part at the end it to avoid including your own links)

This looks for your domain name (outside of your site) – and shows who is mentioning you.
