Yahoo, MetaCrawler, Excite and Dogpile are just a few of the commonly used sites. While all of these sites can be used to find information, and most of them look very similar to one another, they are actually very different from each other. The skill development activities in this section will introduce you to the differences between search sites and demonstrate how to use them. Indexes Indexes such as Yahoo search through indexed pages also called directories. The collection of pages is essentially a database of authoritative sources that have been put together.
Pages have to be submitted and accepted before they can become part of the directory.
When you perform a search using Yahoo, it searches through these directories. The resulting matches will be displayed. The result shows where in the directory the information you requested is located. Yahoo also displays matches that are related to your search. Submitting Web Pages for Inclusion Into a Directory Excite is another example of a directory.
