About Search Engines

Search Crawler or Spider

The search crawler or spider visits a web page, reads it, and then follows links to other pages within the site. This is what it means when someone refers to a site being "spidered" or "crawled." The spider is programmed to return to the site on a regular basis. The more frequently the sites are crawled, the more up-to-date the search results are.  

Everything the spider finds goes into the second part of a search engine, the index. The index is like a database that contains the information the spider found during its crawl. Whenever a user enters a keyword or keywords into the search box, the search engines searches through the index to find the word(s) or phrase and returns the matching results.  

Examples of Search Engines: 

  • AltaVista

  • Excite

  • Google 

Directories

Directories are created by a person who actually creates your website's listing on the search page, as opposed to a 'robot' or 'spider' to do this automatically. A short description and the url to your website is submitted to the search engine owners. If approved, the “search owner” then assigns your website to an appropriate category or categories within the large search website.  

Directories often provide much more targeted results than search engines. A search for the directory site looks for matches only within the descriptions submitted -- not information found on your web pages. To update your web sites description, you typically submit an online update to the search engine's webmaster.  

Examples of Directory Searches:  

  • Yahoo

  • AOL

  • AltaVista
