Results are listed according to how keywords are found on the pages with no significant ranking according to site relevance or popularity. Depending on the keyword(s) used, Excite presents the user first with a category or site listed under "Try These First".

Yahoo continues to be by far the most popular way to find information on the web of any of the search engines and directories. With one of the smallest databases (less than a million sites) Yahoo gets as more traffic than Excite and Altavista put together. Yahoo is successful because its quality control is high providing users with high quality links and without all the redundant listings that plague so many of the search engines. Yahoo is a directory, not a search engine, making it possible to look up information within categories. The result of Yahoo's painstaking efforts to ensure the integrity of its directory is that it is is one of the easiest ways to find information on the web. Yahoo is particularly helpful when looking for types of businesses such as "online brokers". Using Yahoo you'll get an alphabetically organized list of all "online brokers" compared to a typical search engine which provides you with a listing of any page that uses the words online or brokers in its text. Directories like Yahoo won't help you find obscure or current information, though Yahoo now defaults to the comprehensive Google for queries it can't find in its database. While Yahoo is one of the best ways to find information on the net, it does have a number of limitations. To find relevant information can take many steps through a morass of categories. Information in the database is limited for the most part to homepage data and more and more of Yahoo's listings are out-of-date, i.e. to sites that no longer exist.
