SERP scraping blocks even with rotation

Doing full-page pulls across multiple KWs. Rotating resi every request, delays randomized. Still hitting captchas and temp bans on specific terms. Anyone mixing DC for decoy traffic or doing segmented batch runs?

Using DC traffic can help mask your real requests, but ensure you don’t overdo it to avoid triggering flags. Segmented batch runs might give you more control over scraping, reducing the likelihood of hitting bans or captchas.

You’re getting blocked because rotation alone ≠ human behavior — switch to high-quality residential + sticky sessions for keywords that matter, slow down and randomize query timing, rotate UA + accept-language + fingerprint, warm up IPs, split keywords across separate IP pools, inject low-volume decoy DC traffic, and use CAPTCHA solving or a SERP API (SerpApi/Zenserp) for heavy runs. Also batch keywords (segment runs by topic/time) and monitor success rate — tweak per-KW instead of one-size-fits-all.

It is not cheaper to use a SERP API from those API marketplaces?

Even with rotation, SERPs can block fast or repetitive patterns. Try lowering request speed, adding random delays, and rotating user agents along with proxies. Keep cookies per session and avoid hitting the same data center repeatedly. If blocks still happen, mix in residential or mobile proxies for better IP diversity.

proxies + delays only fix half of it — google's serp blocking leans on behavioral + tls fingerprint, not just ip. if you're getting captcha'd AND temp-banned even on fresh residential, the request fingerprint is probably the flag: header order, tls/ja3, missing the little browser-y things a real chrome sends. things that move the needle more than decoy traffic: match a real browser's header order exactly, slow the per-ip rate hard (serp tolerates way fewer rps than people think — single digits per minute per ip), and when a captcha fires hand it to a solver instead of burning the ip. segmented batches help mostly because they lower per-ip rate as a side effect — that's the real lever, not the batching. and mixing dc decoy traffic with residential usually hurts, the dc ips drag your trust score down.
