The internet is a huge repository of knowledge and information, and when the platform is huge, chances of getting lost are huge as well. Link popularity is what separates a page from cyber anonymity. Much like in the real world, the more popular you are, the more you get noticed and more important you are. Many of the search engines treat popular pages as more relevant and important than less popular pages – each link is thought of as a vote for a certain page. More the votes, more is the importance.

As a venue of online commerce, link popularity is not just about fame, but about money. More links translate into better search engine ranks and more page hits, which in turn translate into more sales and more dollars. Online enterprises around the world try to get their pages more popular through a variety of methods – text link advertising, submission to directories, article sponsorships, banner exchanges and link exchanges, etc. As more and more businesses go online, and as more ad-supported sites claim cyberspace, link popularity becomes a critical factor that decides survivability.
