Hi.. what is robot or spider?

[konetkar500]

A Web crawler is a computer program that browses the World Wide Web in a methodical, automated manner or in an orderly fashion.


This process is called Web crawling or spidering. Many sites, in particular search engines, use spidering as a means of providing up-to-date data. Web crawlers are mainly used to create a copy of all the visited pages for later processing by a search engine that will index the downloaded pages to provide fast searches. Crawlers can also be used for automating maintenance tasks on a Web site, such as checking links or validating HTML code. Also, crawlers can be used to gather specific types of information from Web pages, such as harvesting e-mail addresses.


A Web crawler is one type of bot, or software agent. In general, it starts with a list of URLs to visit, called the seeds. As the crawler visits these URLs, it identifies all the hyperlinks in the page and adds them to the list of URLs to visit, called the crawl frontier. URLs from the frontier are recursively visited according to a set of policies.

Many search engines use programs called robots to locate web pages for indexing. These programs are not limited to a predefined list of web pages, instead they follow links on pages they find, which makes them a form of intelligent agent. The process of following links is called spider, wandering, or gathering. Once they have a page or document, the parsing and indexing of the page begins

A spider is an electronic robot which moves through the web examining websites in order to hit on search engine databases and rank them according to the targeted ranking criteria for search engines. Bot & crawler are some other similar names for spiders.

Hi.. what is robot or spider?

Robot - A robot is a program that runs automatically without human intervention. Typically, a robot is endowed with basic logic so that it can react to different situations it may encounter. One common type of robot is a content-indexing spider, or webcrawler.

Spider - A spider is an automated program that "crawls" the Web, generally for the purpose of indexing web pages for use by search engines. Because most web pages contain links to other pages, a spider can start almost anywhere. As soon as it sees a link to another page, it goes off and fetches it. Large search engines have many spiders working in parallel.
