Hello
- A web crawler (otherwise called a web spider or web robot) is a project or robotized script which skims the World Wide Web in an orderly, computerized way.
- This procedure is called Web creeping or spidering.
- Numerous authentic destinations, specifically web indexes, use spidering as a method for giving breakthrough information.

A Web crawler is an Internet bot which systematically browses the World Wide Web, typically for the purpose of Web indexing.
Web search engines and some other sites use Web crawling or spidering software to update their web content or indexes of others sites' web content. Web crawlers can copy all the pages they visit for later processing by a search engine which indexes the downloaded pages so the users can search much more efficiently.
Crawlers consume resources on the systems they visit and often visit sites without tacit approval. Issues of schedule, load, and "politeness" come into play when large collections of pages are accessed. Mechanisms exist for public sites not wishing to be crawled to make this known to the crawling agent.
As the number of pages on the internet is extremely large, even the largest crawlers fall short of making a complete index.

A web crawler (also known as a web spider or web robot) is a program or automated script which browses the World Wide Web in a methodical, automated manner. This process is called Web crawling or spidering. Many legitimate sites, in particular search engines, use spidering as a means of providing up-to-date data.

For instance, including a robots.txt file can request bots to index only parts of a website, or nothing at all.
