A team of more than 20 people have manually categorized the 100,000 most popular web sites on the Internet into one of the categories listed below. When a user utilizing our desktop advertising software visits one of the targeted URL's, if you have bid on the corresponding category, your web site will be displayed to the end user. If multiple advertisers are bidding on a category that you are interested in, higher bids will result in a higher likelihood of their ad being shown, so you can continue to receive new visitors even if you are the lowest bidder.
