How does Ahrefs prioritize which pages to crawl first?
Correct: By a page’s link popularity
Ahrefs prioritizes pages to crawl based on link popularity because its crawler, AhrefsBot, uses a page's backlink profile as the primary indicator of its importance and authority. Specifically, the system utilizes proprietary metrics like URL Rating (UR) and Domain Rating (DR) to determine crawl demand; pages with a higher quantity of high-quality backlinks are seen as more "popular" and are therefore scheduled for more frequent crawling and updates. While organic traffic and CTR are valuable metrics for SEO analysis, they are calculated estimations based on ranking data rather than the foundational signals used by the scheduler to allocate its crawling resources across the web.
