Google residential proxies
Google doesn't outsource its bot defense - it runs a proprietary stack built around IP-reputation scoring, per-IP query-velocity limits, and reCAPTCHA challenges that fire the moment traffic looks automated. A single datacenter IP running repeated queries hits the "our systems have detected unusual traffic" interstitial within minutes. Residential exits from real ISP address space blend into ordinary search traffic, and rotating them per request keeps any single IP well under Google's velocity thresholds.
Google's blocking is driven far more by request velocity and IP reputation than by deep device fingerprinting, so a large, clean residential pool with per-request rotation is usually enough - Elite's city/ISP precision only matters when you need locale-accurate local results.
Why Google is hard
- The "unusual traffic" reCAPTCHA is triggered by per-IP query rate, so throughput on any single exit is tightly capped.
- SERPs shift with the IP's inferred location - gl/hl params help but geo-IP still moves rankings, so wrong-country exits pollute your data.
- Datacenter and hosting ASNs are effectively pre-blocked - Google scores them low-trust before the first query lands.
- Consent screens, SafeSearch defaults, and personalization differ by region, changing the DOM you have to parse.

Targeting & session tips
- Use -country-<cc> to match your target market; the SERP differs noticeably between, say, -country-de and -country-us.
- For local-pack and "near me" queries, step up to city-level (Elite) so map results reflect the right metro.
- Keep a spread of exits per keyword set so rate is distributed across the pool, not concentrated.
