How often should you crawl a site?

Answer

Match crawl frequency to how often content changes and how quickly you need updates. High‑change sites may need multiple crawls per day, while static sites can be crawled far less often. Start with a conservative schedule and adjust based on observed update rates. Pay attention to server responses and slow down if you see rate limits or errors. Your own resource constraints and data freshness goals also matter. The right schedule is a balance of coverage, freshness, and politeness.
