How do Search Engines work?

A Search Engine is comprised of three main elements:

1. THE SPIDER

First is the spider (also known as a crawler). The 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 returns to the site on a regular basis, such as every month or two, to look for changes.

2. THE INDEX

Everything the spider finds goes into the second part of a search engine, the index. The index (sometimes called the catalogue) is like a giant book containing a copy of every web page that the spider finds. If a web page changes, then this book is updated with the new information.

Sometimes it can take a while for new pages or changes that the spider finds to be added to the index. Thus, a web page may have been "spidered" but not yet "indexed." Until it is indexed (added to the index) it is not available to those searching with that search engine. Increasingly, pages that have been submitted are indexed, but the rest of the site will not be spidered for some time.

3. THE SEARCH ENGINE SOFTWARE & USER INTERFACE

Search engine software is the third part of a search engine. This is the program that sifts through the millions of pages recorded in the index to find matches to a search and then ranks them in order of what it believes is most relevant.

Our optimization process is generally combined with Web Site Applications development.

It is best to implement the features into a web site as it is being developed; trying to optimize an existing site can take a lot of redevelopment time and effort.
