How do I evaluate an incoming link to my site?

  • How do search engines evaluate links to my sites? What should I as a siteowner be looking for when seeking out links to my site? Are there some specific factors that determine the eventual weighting of the link for either positive or negative search rankings?

  • PageRank of the Page — The higher the PageRank of the page linking to you the better. The higher the PR of a page linking to you, the more importance Google gives it.

  • Relevance of Page Content — The higher the relevance of the page to the page it is linked to, the higher the link value. If you have a software site with lots of links from other software sites or technology-related organizations those are going to be substantially more effective then non-themed links.
