What are Spiders and What Do They Have to Do with SEO?

If you have ever talked about “searching the Internet” you probably meant that you were searching the World Wide Web. The Internet is a much larger concept, whereas the World Wide Web is the aspect of the Internet that is visible and usable by the public. Finding what you need on the Web can be truly overwhelming if you realize just how expansive this collection of information is. There are literally hundreds of millions of individual Web pages spread across the Web that are available to be accessed and read by anyone who can find them. This, of course, means that internet users must be able to find them.

Website design and search engine spiders

Even before the concept of the World Wide Web was fully developed, search engines had been put into place. These search engines allow Internet users to look for the exact information that they desire so that the engine can find it for them. Rather than just wandering aimlessly throughout the Web, users can put a keyword or phrase into the search engine and be directed to the pages that are most applicable to the search.

Before the engine can direct a user to the information that he wants, however, this information must be found. This is where internet spiders come in.

Internet spiders, also called crawlers, ants, and bots, are specialized software that is charged with exploring the Internet in an effort to index all of the pages available. These spiders crawl around the Internet, following links that connect different pages, exploring these pages, and cataloging all of the information that they come across along the way.

The main purpose of spiders is to create and maintain enormous databases of words that are found on various websites so that they can respond to search engine inquiries with the appropriate websites.

A spider begins crawling on a particularly popular site or within a heavily used server. The spider will crawl around that site, cataloging the words, and then find the links present on the page. Each of these links will be followed, quickly leading to expansive travels around the Web.

Spiders will look not just at the words on the page, but where they are located and how they are utilized. These spiders are only able to travel along links and index text, they cannot perceive video, images, JavaScript, music, or Flash capabilities.

Feeding the Spiders

High quality content on a website is often referred to as “spider food” because it draws the spiders to the page and gives them plenty to crawl around on. In order to maximize the effectiveness and visibility of your website, you must optimize it for the spiders.
Start by creating a site that will appeal to human visitors, meaning that it is visually appealing in addition to containing valuable content. WordPress themes are a fabulous resource for building a site that is organized, polished, and structured in such a way that your spider food can be easily developed and published. Management tools also enable you to specify search terms that will serve as emphasized words when the spiders index the page.

After your page has been created, you will focus on filling it with engaging content anchored with powerful keywords. As the spider crawls through your site it will index the words that you used in your content so that they can be identified by the search engine algorithms.

When the spiders have finished indexing your pages they can be included in search engine results. Essentially this is accomplished by retrieving your site from the index when an internet user searches for a term or word that is used with frequency and effectiveness on your website.

Spiders do not return to the same pages every day, but the more often you add fresh, valuable content to your site or generate natural links, the more you are attracting the spiders to your pages and increasing the chances of improved ranking.
