Rate limits

What an HTTP 429 from Google Trends means, and how to stay under the limit without a proxy pool.

Rate limits

Google Trends aggressively rate-limits datacenter and shared IPs, so 429 is common even on your first request of the day. Two things matter:

  1. User-Agent. Google returns 429 to the default agent strings Python HTTP clients send, no matter how few requests you have made. This library sends a browser User-Agent by default for exactly that reason.
  2. IP reputation. Once an IP is flagged, every request gets 429 regardless of headers. Route through a residential proxy to recover.
