A web directory is basically an organised index of Web sites.

If you own a website and do any kind of online promotion, you should already know the importance of backlinks for search engine rankings and website traffic. Getting links to your site is important for getting visitors and getting listed higher in search engines, with 80% of Google’s ranking believed to be taking this into account.

Web directories can be a great way to build links with just about any budget & bid directories are the latest type of web directory to come about. A bid directory is an organised directory of links sorted by bid amount; the higher the total bid for a link, the higher up it is listed in the directory.

Just like a business might list their company in the Yellow Pages, a website owner can add their link to a bid directory & by spending more on their link, they control how much exposure the link gets.

Usually, the highest bidder on the site takes the “link leader” position, and gets a sitewide link, or other special benefits from the directory owner. This will often result in competition between link owners that keep bidding to maintain the highest spot on a directory. Since link owners can add to their bid at any time, they benefit from having full control over when and how much they spend.
