The Difference Between Good Links and Great Links
Most search engines work around a similar model in which incoming links are one of the most important element in determining a page or site's quality. The higher quality a page, the higher ranking it receives in the engines. Make no doubt about it, all incoming links help boost a page's ranking in most search engines, but some links "count" more than others. Generally speaking, sites with higher rankings provide more authority than those with low rankings.
