quality of the back links which means the link of your site on high pr websites

[jeniferdesauza]

If you search for a famous store, like related:gap.com will see that the first ones are oldnavy and bananarepublic, but that's ok, they are the same company. But all other ones are competitors, they are not linking to each other. I deduce that by careful searching using this feature on various website URLs you can uncover several other sites that Google considers to be authority sites, and it is those that it might be a little bit more valuable to ask for an incoming link.
