A relatively recent addition to the bookofjoe bandwagon just sent me a fascinating Google tool which lets you find out the absolute number of pages that are linking to a given URL.
He said, “Just go to their homepage and type: Link:http://siteaddresshere and it’ll cough up the answer in a jiffy.”
He sent me the results of his experiments; here they are:
Google: 3,030,000 (probably includes all the “Ads by Google” links running in Google-served ads around the Internet)
U2 official band site: 3,880
Kleiner Perkins: 371
Palomar Ventures: 20
