Web crawling is the process of indexing data on web pages by using a program or automated script. These automated scripts or programs are known by multiple names, including web crawler, spider, spider bot, and often shortened to the crawler. Web crawlers copy pages for processing by a search engine, which indexes the downloaded pages so that users can search more efficiently. The goal of a crawler is to learn what web pages are about. This enables users to retrieve any information on one or more pages when it’s needed.

Crawling the web is a process whereby, starting from one or more webpages, a program follows links or fills forms to reach more webpages, downloading the HTML source of the necessary pages on the way. The downloaded pages can be processed for extracting useful information, often indexed to make them searchable.

A web crawler (also known as a crawling agent, a spider bot, web crawling software, website spider, or a search engine bot) is a tool that goes through websites and gathers information. In other words, the spider bot crawls through websites and search engines searching for information.
Web crawlers start from a list of known URLs and crawl these webpages first. After this, web crawlers find hyperlinks to other URLs, and the next step is to crawl them. As a result, this process can be endless. This is why web crawlers will follow particular rules. For example, what pages to crawl, when they should crawl these pages again to check for content updates, and much more.
