Hi Friends,
A spider is a program that visits web sites & reads their pages and other information in order to create entries for a search engine index.

The major search engines on the Web all have such a program, which is also known as a "crawler" or a "bot." Spiders are typically programmed to visit sites that have been submitted by their owners as new or updated.

Entire sites or specific pages can be selectively visited and indexed. Spiders are called spiders because they usually visit many sites in parallel at the same time, their "legs" spanning a large area of the "web."

Hello Friends,

A search engine spider is a program that works behind the scenes to deliver up-to-date Web search results to users through a search engine. The search engine spider can work continuously or respond to user events. Typically, the search engine spider uses specific and ordered methods to scan Web text and index pages for their search engine rankings.
