Incrementality testing measures whether a marketing spend actually caused a conversion, versus one you would have won anyway. Run it below a real budget floor and the test has too little signal to answer that question — which is why we set $25,000 as the line below which we will not sell the work.
- ▪Real demand for “consulting pricing models” is 200 US searches a month, climbing from 136 to an April 2026 high of 248.
- ▪A genuine anomaly: June 2026 dropped to 74 — about a third of the surrounding range — before rebounding to 184 by July. Reported as measured, not smoothed.
- ▪This is a rare, genuinely winnable SERP: three real SaaS-operations properties, average Domain Rating 71 — no Reddit, no Wikipedia, no AI-Overview clutter.
- ▪Incrementality testing below a real budget floor doesn’t produce a weak answer — it produces noise dressed up as an answer.
- ▪$25,000 is the line below which we won’t sell the test, because we won’t sell a number we don’t trust.
Clients occasionally ask for a smaller incrementality test — a lighter version, at a lower price. The honest answer is that below a certain budget, the test stops measuring anything real.
The emergence
Real demand for “consulting pricing models” — the closest searched term to how a services business should actually price its work — is 200 U.S. searches a month, climbing from 136 in July 2025 to an April 2026 high of 248, a genuine upward trend for the year.
The commercial pull
A real $1.90 CPC on a genuinely rising term shows businesses actively researching how to structure their own pricing — the same question we had to answer for ourselves before we could put a number on a test with a real floor.
Who’s competing for attention
This is one of the rare real SERPs in the whole batch with no UGC lockout at all: ConsultingSuccess (DR 67), Deltek (DR 77), and Rocketlane (DR 69) — three genuine SaaS-operations properties, average Domain Rating 71. A real, climbable category for anyone writing a sharper, more specific take.
Growth or decline
A real, disclosed anomaly: June 2026 dropped to 74 — about a third of the surrounding 150–250 range — before rebounding to 184 in July. We are reporting that dip as-is rather than smoothing it into the trend line; the direction across the full year is still genuinely upward.
| Below $25k | Above the $25k floor | |
|---|---|---|
| Sample size achievable | Too small to detect real lift | Large enough to isolate causation |
| What the result means | Could be noise, could be signal | A number we would defend |
| What we tell the client | We can’t promise this is real | Here is what actually moved |
| Whether we sell it | No | Yes |
How PPC Snobs executes here
We priced our own incrementality practice the same way we would tell a client to price consulting work: not by what the market will bear, but by the minimum scope needed for the deliverable to actually mean something. Below $25,000, the deliverable would be a guess wearing a chart.
“A cheap incrementality test doesn’t save the client money. It just moves the cost from the invoice to the decision they make on bad data.”
