Searching the Internet Carefully review the guidelines below on how to use searching commands for a number of search engines. Once you are familiar with one or two search engines that you like to use, you will be able to narrow your search strategies to find the information that you need. They are not the same. The difference is how listings are compiled. Search Engines Directories Search engines create their listings automatically.
Search engines crawl the web, then people search through what they have found.
A directory depends on humans for its listings. You submit a short description to the directory for your entire site, or editors write one for sites they review. A search looks for matches only in the descriptions submitted. The spider visits a web page, reads it, and then follows links to other pages within the site. The spider returns to the site on a regular basis, such as every month or two, to look for changes.
