Crawl Frontier

A crawl frontier is the boundary set by a web crawler that determines which web pages it will visit next. Think of it as a waiting list of pages to be explored, prioritized based on factors like importance, freshness, or relevance. As the crawler discovers new links, these pages are added to the frontier. Managing the crawl frontier helps ensure efficient coverage of the web, avoiding redundant visits and focusing on valuable or updated content. This process helps search engines and data collection systems systematically and efficiently gather web information.
