How many pages or links do I have in google?
To find out how many pages you have in google type in the following: (site:yoururl.com) in the google search engine to find out how many pages you have in google. So If you wanted to find out how many yahoo pages are in google you would type in "site:yahoo.com" and would eventually lead to the following URL: http://www.google.com/search?num=100&hl=en&lr=&safe=off&c2coff=1&q=site% 3Ayahoo.com which in this case yahoo has 20,700,000 pages in google.

To findout how many backlinks you have in google you would replace site: with (link: yoursite.com) so in this example yahoo has around 12,300,000(or more or less) backlinks in google as defined at the URL: http://www.google.com/search?num=100&hl=en&lr=&safe=off&c2coff=1&q=link% 3A+yahoo.com.

Hope this helps you understand how your performance in google is doing.
