📌 What is Crawl Rate? #
- Crawl rate = How many requests Googlebot makes to your site in a given period.
- Google’s system auto-optimizes crawl rate to avoid overloading servers.
- Sometimes crawl rate spikes → may cause server load or cost issues.
⚠️ Common Reasons for Crawl Spikes #
- Faceted navigation (filter/sort pages generating many URLs)
- Calendars (lots of date-based URLs)
- Dynamic Search Ads targets
- Inefficient URL structure
👉 Fix: Review site structure, use robots.txt, noindex, or URL parameter handling in Search Console.
🚑 Emergency Crawl Rate Reduction #
If Googlebot is causing server strain, temporarily:
- Return these HTTP status codes to Googlebot:
- 500 (Server error)
- 503 (Service unavailable)
- 429 (Too many requests)
- 500 (Server error)
✅ Google will slow down crawling automatically.
⚠️ Do NOT keep this for more than 1–2 days (it can hurt indexing & rankings).
📤 Permanent / Special Request #
If you cannot return error codes:
- Submit a special request in Google Search Console → “Report Problem with Crawl Rate”
- Mention your optimal crawl rate
- Google will evaluate (can take a few days)
📌 FSIDM Tip for Students #
- Reducing crawl rate = last resort for emergencies (server overload or outages)
- For long-term efficiency:
- Use robots.txt wisely
- Consolidate duplicate/parameterized URLs
- Optimize site architecture for efficient crawling
- Use robots.txt wisely
