A spider is a program that automatically fetches Web pages. Spiders are used to feed pages to search engines.Its also known as a robot or a crawler, is actually just a program that follows, or "crawls", links throughout the internet, grabbing content from sites and adding it to search engine indexes.
Spiders only can follow links from one page to another and from one site to another. That is the primary reason why links to your site (inbound links) are so important. Links to your website from other websites will give the search engine spiders more "food" to chew on. The more times they find links to your site, the more times they will stop by and visit. Google especially relies on its spiders to create their vast index of listings.
