Link popularity is a qualitative evaluation of a web page based on the number and quality of links that point to the specified web page.
Link popularity affects ranking in the web pages. In a comprehensive search engine marketing campaign, backlinks, also called inbound links are acquired from relevant web pages to point to your web page being optimized.
The more high quality, relevant and high traffic links you can acquire to point to your specified web page the greater your link popularity will be for that page. If you achieve a high score for link popularity you are likely to appear in the top listing positions in the search engine results pages for the terms you have optimized for on that particular web page.
