§ SIGNAL / AUDIENCE INTELLIGENCE · UPLIFT / FILED 2026
Response models find people likely to convert. That is the wrong question: many of them convert without you. Signal ranks audiences by uplift — the change your spend causes — and treats “do not touch” as a targeting decision of equal rank to “reach.”
§01 · The four quadrants
Convert if reached, don't if not. The only quadrant where ad spend creates revenue — bids scale up here.
Convert either way. Every impression and every coupon sent here is margin given away. Maintain presence, stop paying premiums.
Don't convert either way. Budget spent here is simply burned — suppressed.
Convert only if left alone — outreach actively pushes them away. The most expensive audience to reach, in both directions. Excluded.
The quadrants are estimated per segment with uplift models over registered experiments — the same holdout machinery as the credit ledger, pointed forward.
Field note — composite scenario · illustrative numbers
Retargeting is our best channel. The dashboard says 8x. So why does growth feel stuck?
You were paying a doorman to open a door people were already walking through.
§02 · The cohort gate
Activation guardrails — operating defaults, every one enforced before a dollar moves
| Guardrail | Default | Why |
|---|---|---|
| Cohort size | 100 – 500,000 users | below: statistical noise · above: platform limits |
| Qini coefficient | ≥ 0.02 | the model must beat random targeting |
| Area under uplift curve | ≥ 0.55 | ranking quality proven, not presumed |
| Average treatment effect | ≥ 0.5pp | lift worth acting on at all |
| Frequency | capped per user · per channel · per day | audience protection |
Cohorts that pass export to Google Customer Match, Meta Custom Audiences, or lifecycle email — with predicted incremental return computed before activation, and the measured version written back after — operating design, in development.
§03 · Suppression
Discounts routed away from sure-buyers — the composite in the field notes where roughly a fifth of sends were pure margin giveaway is this quadrant, priced.
Negative-uplift segments are excluded from campaigns entirely. Fewer unsubscribes, fewer hides, better delivery reputation on everything that still sends.
Suppression coordinates with Creative Intelligence: an audience marked fatigued for an asset stops seeing it before annoyance becomes attrition.
§04 · Ahead of the funnel
Signal is being extended to read emerging intent from consented behavioral signals and classify where a customer sits on the path from awareness to purchase-imminent — so audiences can be built from where demand is going, not only where it has been. Predictions will ship with calibrated probabilities and the explanation path that produced them.
One rule keeps it honest when it ships: acting on a predicted audience always runs against a registered holdout, so anticipation is never mistaken for causation. The prediction never grades itself.
Stated plainly: this capability is in development, not deployed. Consent decides ingestion; sensitive categories are refused at the schema level; Signal uses no microphone or audio signals of any kind — not now, not on the roadmap.
§05 · See it run
The Signal Factory desk runs the full seven-stage SRPVDAL loop on live runtime — including a deliberate guardrail block you'll watch get caught in red. No signup, no sales call.
