Many top SEOs agree that finding external links (links
directing to your site from another website or blog) is the single most
important objective of attaining high rankings. Many people base this belief on
the idea that external linking can be difficult to manipulate and heavily
relies on third parties that considering your website as relevant or have
influence. A high number of links to your site that show up in a variety
of places on the internet is indicative of its popularity. This method was
first used by one of the first search engines, Alta Vista and was later
improved Google.
