What Is a Crawler in a Search Engine

Crawlers, on the other hand, behave differently depending on the search engine. However, the primary responsibility is to identify and index online pages. To complete the work, search engine crawlers must crawl millions of web pages daily.

However, in most cases, crawlers discover new web pages through backlinks. This is because, as previously said, search engine crawlers browse web pages online. They normally index new websites when discovering new pages linked to previously indexed ones.
