Register your site in Google Webmaster Tools. There you can find all the incoming external and internal links.
Are you trying to see how many backlinks from google you have or are you trying to find a way to get google backlinks?
I recommend you to use Yahoo Explorer. http://siteexplorer.search.yahoo.com It's better than Google Webmaster Tools to find ther backlinks
if you are looking for backlinks from the big G, you may want to look at Angela's packet. A few months back she showed how you could get backlinks from Google.
Ring up google and ask them to put your link on their homepage. They will give you a footer link. Just tell them where you want the link to go. Example in the footer links between "Advertising Programs" and "Business Solutions" or next to "about google".
Well, If you want to have backlinks build links to your site and if you want to know the number of your backlinks use tools like backlinkwatch, link diagnosis or yahoo.com.
It would be better to send them an email which explains the benefits of links trading and how much trading links with his/her site will help Google's ranking and traffic
At first you should make a query: link:yoursite.com -site:yoursite.com Then you won't see links from your own site. And even this may be the wrong way because you'll see only the best links. If you need all links go to Google Webmaster Tools. If you don't want to register in Google Webmaster Tools, verify your site then go to Yahoo links http://siteexplorer.search.yahoo.com/search?p=yoursite.com&bwm=i&bwmo=d&bwmf=s But notice that it shows rel="nofollow" links that doesn't count for Google.
You can do link building. Do directory submission, article submission, blog creation, forum participation and so on.
omg that much work :O pay some one to do that for u heheh just kidding whats in counting making links is more important brother
