Search Engine Basics
Search engines are computer programs that are used to explore the internet in search of web pages. They do this by using "spiders," "crawlers," or "robots" which are used to search for the most up to date information on any given search request. This may seem like an odd place to introduce you to the search engines, but I can assure that this section is well placed. Giving you the basics here will help you to understand what I am saying in the later sections. Anyways… back to the basics and explanation of search engine spiders.
These spiders (like those that are used by Google) are able to follow the links present on web pages that are located by specific keywords. When spiders are searching for a new webpage, they copy all or parts of the text present on the page into their search engine database. Other spiders revisit these pages on a regular basis so that they can register changes or dead links. The wait time varies greatly from search engine to search engine. It is for this reason that your website should stay current.
