Correct: Crawler
Ahrefs’ main source of discovering new pages is the Crawler, specifically their proprietary bot known as AhrefsBot, which constantly traverses the live web by following links from known pages to find new or updated content. While the Scheduler determines the frequency of these visits and the Indexer organizes the collected data into a searchable database, it is the crawler itself that performs the actual discovery and retrieval of raw HTML data. This continuous crawling process is what allows Ahrefs to maintain one of the world's largest third-party search databases and provide up-to-date backlink and keyword information.
