Link Popularity Tool
Link Popularity is a measure of the number of website linking to your website. This tool was designed to allow you to measure your overall popularity and compare your website against your competitors’.
Link popularity is becoming one of the most important considerations for search engines in ranking. Remember that quality and relevant links (and not the number of links) will be rewarded by search engines with higher rankings. Getting links from irrelevant websites, link farms and other suspect sources will hurt you.
