Web directories are always changing. The new version of the web directory has emerged and its better known as the bidding web directory. These types of directories are good for two reasons.

The first reason is for the buyer. Most of the categories do not fill up very quickly which leaves you an opportunity to get a low cost link 1 step from the homepage. This will most definetly give you some good linking power.

The second reason is for the owner. Bidding directories can get intense if the buyers get into a bidding war. Every one wants to be on the first page and will do anything to stay there. Meaning the bids just keep getting higher and higher.

Bidding directories are also good for promoting your own directory since it will send targetted traffic. So if you own a directory it would be wise to submit to other bidding directories that have a category for paid directories or bidding directories. These are also looked as relevant links so it helps you much more in the SERPs.
