Supply Bench wave scorecard
Dated remnant scorecard from August 2026 Supply Bench waves. Partial coverage. No IVT vendor. Not an industry average.
Published 2026-09-09 · Search job: remnant display placement waste
Last measured: 2026-09-02, read-only inventory_agg and domain_agg for Supply Bench waves flown in August 2026. This is a seat-measured slice, not a category benchmark. If a later covered pull disagrees, we will edit this page and date the change.
Coverage (read this first)
This seat ignores report offset. A 50,000-row limit returns 400. The pull kept the top rows by spend: about $316.64 of a roughly $432 combined-wave total on the placement view, and $330.30 on the domain view. Every share below is biased toward larger placements. The missing tail is many tiny rows. Partial coverage is part of the finding.
Campaign-grain dashboards could not answer placement, domain, seller, or SSP identity. We pulled those views because the exchange had already billed them.
No IVT vendor was attached. invalid_impressions and viewable_impressions are not a quality score on this flight. Zero means nothing was measuring.
Placement and domain grain
| Signal | Number | Reading |
|---|---|---|
| Placements in the slice | 1,149 | Long tail, not a short list of slots |
| Domains in the slice | 1,535 | Same spray at domain grain |
| Zero-click placements | 93.4 percent (1,073) | Most slots did nothing measurable |
| Spend on those zero-click placements | $202.77, 64 percent of observed spend | The money followed the empty slots |
| Click concentration | 7 domains = 41.3 percent of clicks from 4.7 percent of impressions | Billed clicks are concentrated, not evenly earned |
| Unauthorized ads.txt spend | $0.48 | ads.txt would not have saved this buy |
| Reseller vs direct CTR | 0.423 percent vs 0.184 percent | Resold paths clicked 2.3 times more |
| SSP CTR range (same creative) | OPENX 0.111 percent to SMARTADSERVER 3.074 percent | Supply behavior, not a new banner |
Do not quote the billed click total as engagement. Roughly two fifths of clicks in this slice sit on the seven-domain set.
What we will not claim
We will not say the flight was high fraud or low fraud. We will not treat 93.4 percent zero-click placements as a universal remnant constant. We will not promote ads.txt as the fix. We will not turn OPENX's 0.111 percent into "never buy that exchange" without a later judged exclude.
environments=['web'] held (app_agg returned 0 rows). Browser games and utilities still appeared. Web-only is not "no casual inventory."
How to use this scorecard
Compare a new covered pull to these rows. If coverage is again partial, say so. Judge the next flight on concentration and click-to-page-view, and on IVT only after a vendor tag is on.
The watchlist of repeat domains is click contamination watchlist. How we read any remnant report is how to judge display traffic.
