Link popularity score is a figure that shows how many pages link to each page on your site. You wouldn't need to know it, but that major search engines use it extensively in their algorithms to assign Web pages high rankings.
The reasoning behind link popularity is simple: the more popular your website with other websites, the higher it will rank on popular search keywords.
Daily webmasters and novice SEOs(search engine optimizers) ask us why their pages are poorly ranked though they have followed SEO advice. Too often we see well-optimized pages lacking in inbound links and it becomes obvious at once they will not rank high on good keywords because their link popularity score is too low.
The Link Popularity Analysis is essential for developing and maintaining your link popularity (read: growing traffic from search engines and your business).
