The main function of Internet search engines is to assist users in finding products and services on the worldwide web. Search engines try to group similar items together under a general topic so that users can narrow down their search. Some search engines allow advertisements of certain merchandise and resources to appear throughout their site.
Search engines allow potential buyers to access sites that participate in Internet commerce.
As transactions over the Internet become more of a norm, the availability of transaction based sites via search engines will be common. Excite provides users with free email service, a chat room as well as a reference tool. Local weather conditions and those across the nation can be obtained using Excite. Yahoo conducts online auctions that allow users to bid on products and sell products for free. A variety of games like chess and spades can be accessed using Yahoo.
