More and more search engines rank your web pages based on the number of links that point to your web site.
Google uses link popularity as the most important factor in ranking sites. HotBot, AltaVista, MSN, Inktomi, and others also use link popularity in their formulas. Eventually, all major search engines will use link popularity, so it's essential to observe and improve your link popularity.
A high link popularity is important for a high ranking on search engines. The higher your web site ranks on search engines, the more customers you'll get.
Link Popularity Check tells you how "popular" search engines believe your site to be. You can also see how popular your competitor web sites are. Each number in the main window's list represent the number of web site links that link to your web site in a search engine. Right-click a domain name and select "Show Link Popularity In <search engine>" to get a detailed list of how many and which web sites link to you.
How does link popularity affect my search engine ranking?
Increasing the number of quality links to your web site improves your search engine rankings. Not only will you rank better in search engines, but links from other web sites also mean more (targeted) traffic to your site. |
