A “Crawler” is a program or automated script used by search engines to scan, index, and store information about websites and their content. The purpose of a crawler is to help search engines understand what a website is about and what information it provides, so that they can include the site in their index and provide relevant search results.
Crawlers visit a website, follow its links, and retrieve information about the pages and their content, including the page title, description, and keywords. This information is then used to generate an index of the site and provide relevant search results to users.
Crawlers can also be used by other types of software, such as site analysis tools, to analyze a website and gather information about its structure, performance, and other factors that are relevant to search engine optimization and website design
