Googlebot uses desktop and smartphone user agents. Under mobile-first indexing, the smartphone crawler handles most indexing-related crawling. A user-agent string alone does not prove a request is genuine: verify requests through Google’s documented IP or reverse-and-forward DNS checks, including relevant googlebot.com hostnames. This helps distinguish genuine crawling from scrapers that impersonate Googlebot. Server-log analysis reveals actual visit frequency and URL patterns and is important for diagnosing crawl-budget issues on large sites.
Search visibility depends on Google being able to retrieve the content and resources it needs.
Verify user agents alongside Google’s documented network identifiers to distinguish legitimate crawlers from impersonators.
