Steps

  1. Provision a Google Cloud API key and enable the PageSpeed Insights API, which grants 25,000 free queries/day
  2. Throttle bulk jobs to stay under the 400-queries-per-100-seconds burst limit, which is enforced independently of the daily cap
  3. Queue and retry with backoff on 429 responses rather than firing all URLs concurrently
  4. Request a quota increase through Google Cloud Console if a legitimate large-scale audit need exceeds 25,000/day
  5. Track mobile vs desktop strategy requests separately, since each counts as its own query against the same quota
