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.
