What do you mean by a crawler?

[ecozaar]

A crawler is a program that visits Web sites and 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 "spider" or a "bot."

Crawlers 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. Crawlers apparently gained the name because they crawl through a site a page at a time, following the links to other pages on the site until all pages have been read.

A search engine crawler is a program or automated script that browses the World Wide Web in a methodical manner in order to provide up to date data to the particular search engine. While search engine crawlers go by many different names, such as web spiders and automatic indexers, the job of the search engine crawler is still the same.

The process of web crawling involves a set of website URLs that need to be visited, called seeds, and then the search engine crawler visits each web page and identifies all the hyperlinks on the page, adding them to the list of places to crawl. URLs from this list are re-visited occasionally according to the policies in place for the search engine.
