For brands, a broken MAP quietly erodes margin and channel trust - one seller undercutting the floor pressures everyone. Catching it means watching every seller on every marketplace, which requires automated MAP price scraping across the web.
This report uses price scraping of publicly listed offers to measure how often US prices break MAP, which channels and categories violate most, and how fast violations appear. It is the context any brand relying on competitor price scraping or a compliance feed needs to protect its pricing.
Key findings at a glance
Three patterns stand out across the compliance data. (Figures are illustrative previews - the full report breaks them down by channel and category.)
Key finding 1: violations concentrate in third-party channels
Authorized retailers largely hold MAP; third-party marketplace and resale sellers break it most. So a brand watching only its official channels misses the bulk of the problem.
This is why MAP price scraping must cover every seller on a listing, not just the featured offer - the violation is often a smaller seller undercutting quietly.
Key finding 2: violations are fast and intermittent
MAP breaks are not static - a seller may drop below MAP for hours then revert, which makes point-in-time checks unreliable. The sample shows violation persistence (illustrative).
| Pattern | Share | Detection need |
|---|---|---|
| Persistent (days) | 40% | Daily scan catches |
| Intermittent (hours) | 45% | Needs frequent scan |
| Flash (minutes) | 15% | Hard to catch |
Because most violations are intermittent, frequent price scraping with timestamps - not a one-time check - is what reliably surfaces them.
Key finding 3: evidence beats alerts
A useful MAP program does not just flag a low price - it captures evidence: the seller, the offer price, the timestamp, and a matched product identity, so the brand can act with proof. MAP price scraping that records matched, timestamped, seller-level offers turns vague suspicion into an enforceable case. Matching is critical - a false match accuses the wrong seller.
What the underlying data looks like
The report is built from seller-level offer records like the one below - the structure buyers receive in a sample.

"violation": true,

Methodology & data
The findings are based on MAP price scraping of publicly listed offers across marketplaces and retailers in 2026, capturing seller-level offer prices matched to products and compared against MAP, with timestamps to measure persistence. No personal data is involved. The full report details the channels, categories and how each metric is calculated.
The numbers and charts shown on this page are illustrative previews of the kind of analysis in the report. They are based on publicly available, non-personal web data in aggregate and do not represent any single named company. The full report contains the complete dataset, methodology and sources.
