A genuine product selling at half its street price is rarely a deal. Systematic price monitoring catches counterfeit listings before image or text matching does.

## The discount threshold heuristic

Counterfeit sellers price to move volume: typically thirty to sixty percent below genuine street price. A watch rule flagging any listing beyond that band on your core products surfaces candidates quickly.

## Price plus seller age narrows fast

A deep discount from a storefront opened last month, with a handful of reviews, is a high-confidence counterfeit signal. Combining price with seller age and review velocity beats any single check.

## Where price monitoring fails

Premium counterfeits priced near genuine levels escape price screens entirely. Price is a first-pass filter, not a detector; visual and text checks still decide the filing.

## Feeding price signals into takedowns

A flagged listing still needs evidence before a filing. Treat price alerts as the top of a funnel: flag, verify imagery and seller history, then file.
