They are called spiders because they crawl over the Web in search of content . Search engines gather data about a website by sending' the spider or bots to read' the site and copy its content. This content is stored in the search engine's database. As they copy and absorb content from one document, they create record links and send other bots to make copies of content on those linked documents this process goes on and on. As of now the major search engines have established databases that measure their size in the tens of billions using this process.

A spider is a program which browses the World Wide Web in a methodical, automated manner. A web crawler is one type of bot. Web crawlers not only keep a copy of all the visited pages for later processing - for example by a search engine but also index these pages to make the search narrower.

A Spider is a program, developed to scan the web page. The Spider scans the entire page, indexes it and lists it on the search engine. It evaluates any particular web page based on several different factors such as keywords, table, page titles, body copy etc. Since listings are done automatically, it can change if you change some content of the website.

Spider is a catch-all, or generic term for programs and automated scripts that “crawl” through the web (the Internet) and collect data from websites and anything else on the Internet that they can find.
