What is Crawler
A crawler is
a computer program that automatically searches documents on the Web. Crawlers are primarily programmed
for repetitive actions so that browsing is automated. Search engines use crawlers most frequently to browse
the internet and build an index.
A Web crawler,
sometimes called a spider or spider-bot and often shortened to crawler, is an
Internet bot that systematically browses the World Wide Web, typically for the
purpose of Web indexing.
Crawling is when Google or another search engine send a bot to a web page or web post and “read” the page. ... Crawling is the first part of having a search engine recognize your page and show it in search results.
