Crawl depth refers to how many links deep a search engine crawler needs to follow, starting from a website’s homepage, to reach a specific page, closely related to but distinct from click depth as experienced by an actual user.
Pages with excessive crawl depth are less likely to be crawled frequently, since search engines generally prioritize crawling resources toward pages that are more prominently linked and closer to a site’s primary navigation structure.
Reducing crawl depth for important pages, through improved internal linking and simplified site architecture, helps ensure search engines discover and revisit those pages more reliably and frequently.
