Domain popularity is one of the highly valued factors that help search engines to assess the importance of your website in comparison with the other websites in a particular field. Greater the number of domains that link to your website, greater the domain popularity. Domain popularity will help you increase your website�s ranking in search results and also increase your website�s PageRank in Google.
