Captcha solving for ad verification

Verification crawlers have to look like ordinary traffic and still get through the challenge. Solve it per request, with failures never billed.

Who this is for

Ad-verification vendors, affiliate-compliance teams, brand-protection and anti-counterfeiting units, and coupon and deal-site monitors. Most are working under contract for the brand whose ads or marks are involved. The crawl is continuous and fanned out by geo, because a placement that was compliant this morning may not be this evening.

The problem

Verification only means something if it runs from the consumer’s actual geo, on the live page, at scale, which is exactly the traffic pattern bot defences exist to stop. Affiliates push scraped exclusive codes onto public deal sites and counterfeit listings churn daily, so a weekly sample misses most of what you are looking for. A crawl that gets challenged returns evidence too thin to put in a takedown.

  • placements are checked from the geo they were bought in
  • monitoring runs continuously instead of sampling weekly
  • screenshots and DOM evidence are captured after the challenge, not before it
  • the solve uses the same proxy as the check, so geo stays consistent

Questions about this one

Yes. Proxy-backed task types take your proxy details, so the challenge is solved from the same geo the check runs in. That matters more here than in most scenarios.

DataDome and PerimeterX on the larger ones, Turnstile and reCAPTCHA v3 almost everywhere else, plus plain image challenges on smaller affiliate pages.

No. The solve happens before the page reaches its final state, so the screenshot and DOM you capture are what a consumer in that geo would get.

Concurrency is an account-level setting rather than a per-geo quota, so a fan-out across hundreds of locations shares one ceiling.
