Top Sites

The top ranked sites in each category. Many listings in Top Sites by Category are for specific pages or subdirectories, not for entire sites. For example, in the Reference > Maps section you'll find mapquest.com (an entire site about maps) and maps.yahoo.com (one section about maps on a larger site).

For this reason, the listings in the Top Sites by Category are ordered by Popularity of this listing, and not by the overall Traffic Rank of the site. We use the same basic traffic ranking technology used for Alexa Traffic Rank — a combination of users and page views — but apply it only to the traffic for that specific listing. To find out the Traffic Rank of any site in the Top Sites by Category directory, just click the name of the site and you'll be taken to the "Site Info" page for that site.
