    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

    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.

    Web Crawling is basically a tool used by search engines to map out websites, it can be used to collect certain data of websites and that would be called web scraping. You can use specific keywords to search on a certain website and the bot would return the data from the chosen website.

    When you do crawl a website, make sure to heed any HTTP 429 (too many requests) responses you get and don't send an excessive number of requests in the first place or you will likely get automatically banned.

    A web crawler copies webpages so that they can be processed later by the search engine, which indexes the downloaded pages. This allows users of the search engine to find webpages quickly. The web crawler also validates links and HTML code, and sometimes it extracts other information from the website.

    A Web crawler, sometimes called a spider or spiderbot and often shortened to crawler, is an Internet bot that systematically browses the World Wide Web, typically for the purpose of Web indexing.
