How to preserve evidence of counterfeit marketplace listings before they disappear

Capture the listing before you report it: full-page screenshots showing the URL and date, the seller’s storefront name and details, your own records of the genuine product and registrations, and — in some matters — a documented test purchase that counsel may consider recommending. Listings, seller names, and reviews can change or disappear without notice, and what you did not capture may be hard to reconstruct later.

Who this is for: brand owners and rights holders who have found counterfeit or copycat versions of their products on online marketplaces. If you received a takedown notice or are accused of infringement, this article is not for your situation.

Why evidence comes first

Marketplace listings can change without notice — a seller may edit a title, swap images, or close a storefront. Enforcement options that exist later — platform escalation, demand letters, federal litigation — all depend on what was documented earlier. A platform complaint that fails can become part of the record that shapes the next step, so the quality of the underlying capture matters from day one.

What to capture — a checklist

1. The listing itself: full-page screenshots that include the browser address bar (URL) and the current date; the listing title, price, images, and description; the product identifier (e.g., ASIN on Amazon).
2. The seller: storefront name, seller profile page, any business name or address the platform discloses, and other listings by the same seller.
3. Context: your search position or category placement showing how buyers find it; review text that suggests buyers believe they are getting your product.
4. Your side: your registration certificates (trademark/copyright), your genuine listing, and your own product photos with creation dates.
5. Purchase evidence, only if counsel recommends it: in some matters counsel may consider a documented test purchase to establish what is actually being sold and shipped. It has cost, timing, and tactical implications, so do not make purchases or contact the seller before speaking with counsel.

For each capture, record the date, time, and who made it. Keep files in original form; do not crop, annotate, or rename the only copy.

Decision factors

• How many listings and sellers? One listing may justify a platform complaint; a pattern may justify escalation.
• Registered or unregistered rights? Platform programs and federal claims both turn on what is registered and where.
• How fast is harm accumulating? Ongoing sales during a sales season may change the urgency calculus.

Limitations

This article describes general evidence-preservation practice for U.S. brand owners. It does not address evidentiary admissibility in any particular court, foreign platforms, or situations where you have already received a threat or complaint. Platform tools and requirements change; verify current requirements at the time you act. Information only — not legal advice.
