Amazon residential proxies
Amazon runs its own proprietary anti-automation stack rather than a third-party CDN vendor: layered request fingerprinting, velocity checks, and the familiar rendered image CAPTCHA that appears the moment traffic looks non-human. The public data worth pulling - Buy Box ownership, offer listings, price history, Best Sellers Rank, review counts and star distributions - is served differently depending on the marketplace domain and the shopper's inferred location. Routing each request through a residential IP on a consumer ISP makes the traffic read as an ordinary shopper, so listings render in full rather than collapsing into a CAPTCHA or a stripped-down page.
Amazon's defenses key heavily on request velocity and IP reputation rather than the hardest browser-fingerprint challenges, so a large, clean residential pool with disciplined pacing clears most catalog and pricing work. Premium's balance of cost and reliability fits high-volume price monitoring; reserve Elite only if you need locale-locked Buy Box checks from specific cities.
Why Amazon is hard
- The rendered image CAPTCHA ("Type the characters you see") is triggered by request velocity and reused IPs, not just by missing headers.
- Buy Box winner and pricing shift with the shopper's inferred delivery location, so a single vantage point misrepresents the offer.
- Best Sellers Rank and review pagination throttle aggressively under repeated hits from the same exit.
- Each marketplace (.com, .co.uk, .de, .co.jp) behaves as a separate property with its own catalog and pricing rules.
How to approach Amazon with Aethyn
Targeting & session tips
- Match -country to the TLD: -country-de for amazon.de, -country-gb for amazon.co.uk.
- For delivery-sensitive Buy Box checks, add city targeting to approximate a real shopper's postcode region.
- Rotate per request for broad BSR and category sweeps where each URL is independent.
- Keep a session sticky only as long as a single ASIN's paginated detail crawl.
