Read Supply Audit findings by detector
Four detectors, default thresholds, and the first production mix. Zero findings on an incomplete scan is not a clean bill of health.
Published 2026-09-10 · Search job: supply audit zero click spend threshold
Read a Supply Audit finding by detector name, not by a single "waste" total. The four detectors are pure functions with default thresholds. The scan recommends. It does not pause and it does not exclude.
| Detector | Meaning | Default threshold |
|---|---|---|
zero_click_spend | Inventory took budget and produced no clicks | 500 impressions and $5.00 spend |
high_ctr_no_downstream | CTR far above the account baseline | 100 impressions, 1% absolute floor, 5x account baseline |
low_click_to_pageview | Billed clicks that never became a landing page view | 25 clicks, 2% pageview rate |
unauthorized_ads_txt_delivery | Delivery on inventory the publisher did not authorize | any |
high_ctr_no_downstream is the detector that would have caught the August 2026 Supply Bench waves. CTR here is a contamination signal, not a success score. See CTR is a trap.
First production mix
Window 2026-08-26 through 2026-09-01. 3,591 entities evaluated.
| Detector | Findings | Flagged spend |
|---|---|---|
zero_click_spend | 12 | $82.45 (16,768 impressions, 0 clicks) |
unauthorized_ads_txt_delivery | 47 | $32.51 |
high_ctr_no_downstream | 15 | $23.57 (4,825 impressions, 180 clicks) |
74 findings, $138.53 of $320.67 audited spend. That headline is a lower bound after the Math.max fix. low_click_to_pageview has not produced a finding. Do not read a quiet detector as "every click landed."

Checklist before you act
- Is
coverage_verdictcovered? If not, stop. Incomplete coverage is not clean. - Which detector fired? Thresholds above are defaults, not moral judgments.
- Which grain is the entity? Split composite keys before you exclude.
- Apply creates targeting. Point the next campaign at it.
- Do not decide on CTR. Do not claim IVT from this scan. The first production run did not have a measurement vendor on the creatives.
Dated mix lives on Grain-level waste mix.
