What is link popularity?

Think of the search engines as a big election. All the websites in the world are candidates the links to your website are votes. The more votes (links) a candidate (website) has, the more important it is, and the higher its ranking. Link popularity is all about how many links you have, and how you can get more.
Links to your site tell the search engines how important your site is. They assume that if itÂ’s important enough for a lot of other sites to link to, itÂ’s important enough for them to display at the top of the rankings. Links are the single most important factor in ranking.
Generally speaking, the more links you have to your site form other sites, the better your ranking.
