A triage guide for the common proxy failures: authentication errors, 403s from origin versus proxy, CONNECT timeouts, TLS mismatches and country mismatches.
A plain-language overview with primary sources: what US courts have held, the EU position on personal data, and why terms of service are the real risk.
A practical framework for collection work: public versus personal data, proportionality, retention limits, robots and terms, and a pre-launch checklist.
Why contributor platforms screen for duplicate accounts and fraud, why location matters, and the legitimate case for a stable local address.
Agents that browse need geo-correct egress, rate-limit awareness and auditability. How to give each agent an identity, control sessions and bound retry costs.
How content classification works, why categories affect ad placement and filtering, how misclassification happens, and how to verify a category locally.
Designing tests that isolate geography: the same query from different city addresses, a fixed device profile, and a clean record of what each market returned.
Checking that campaigns render in the intended geo, device and placement, detecting fraud signals, and capturing evidence that holds up in a dispute.
Localised rank checks, competitor content monitoring and indexation checks, and why datacenter addresses return results a real user never sees.
Rank tracking across locations and devices: geo-specific addresses, language and device settings, sampling strategy, and why the raw SERP is not the real one.
Detecting counterfeits and MAP violations across marketplaces, capturing evidence from a local vantage point, and reporting with few false positives.
Allocating address types per task: datacenter for bulk catalogue reads, residential for localised pricing, ISP for account work, with a cost-aware schedule.
Build versus buy for price monitoring: what commercial platforms cover, what they miss, and when an in-house collector on a proxy network is the better trade.
Classified page structure, deduplicating reposted listings, per-city scoping and the polite request rates that keep a classifieds collector running.
Listing structure, search and map endpoints, normalising property records across markets, and the per-market IP requirement for accurate property data.
The Places API versus collecting from Maps pages: what each returns, the real cost trade-off, and why the address location changes local rankings.
Temu renders almost everything client-side and the data is heavily app-centric. How to find the underlying endpoints and what that means for your proxy layer.
A step-by-step build: scheduled fetch, price and availability parsing, history storage and change alerts, with per-marketplace proxy configuration.
Amazon localises by marketplace and rate-limits hard. What each domain returns, how review pagination actually works, and when the official API is enough.
What to collect from retail sites, the defences you will meet, the tooling choices, and the proxy layer that decides whether collection scales.
