What is a Web Crawler?




 A web crawler is a relatively simple automated program, or script, that methodically scans or "crawls" through Internet pages to create an index of the data it's looking for; these programs are usually made to be used only once, but they can be programmed for long-term usage as well. There are several uses for the program, perhaps the most popular being search engines using it to provide webs surfers with relevant websites. Other users include linguists and market researchers, or anyone trying to search information from the Internet in an organized manner. Alternative names for a web crawler include web spider, web robot, bot, crawler, and automatic indexer. Crawler programs can be purchased on the Internet, or from many companies that sell computer software, and the programs can be downloaded to most computers.




 There are various uses for web crawlers, but essentially a web crawler may be used by anyone seeking to collect information out on the Internet. Search engines frequently use web crawlers to collect information about what is available on public web pages. Their primary purpose is to collect data so that when Internet surfers enter a search term on their site, they can quickly provide the surfer with relevant web sites. Linguists may use a web crawler to perform a textual analysis; that is, they may comb the Internet to determine what words are commonly used today. Market researchers may use a web crawler to determine and assess trends in a given market.
