Search Engine Optimization - What is a search engine?

Search engines use indexing software programs, called robots or spiders.

These software programs are programmed to constantly crawl the web in search of new or updated pages. They will go from URL to URL until they have visited every web site on the Internet.

When visiting a web site, a search engine spider will record the full text of every page found (including sub-pages). After that, it will continue to visit all external links. The URL of a web page is the address of a web Page.

By following external links that point to your web site, search engines are able to find your site.

The search engine spiders will then revisit your site periodically to refresh the recorded information.

Search engines rank your web pages based on mathematical formulas.
