Measurement & attribution
Measurement that connects ad spend to the business.
We set up tracking, attribution and reporting that show what paid media is really producing, in customers, revenue and margin, rather than only what each platform claims.
The thinking
Why it works this way
Every ad platform grades its own homework. Google and Meta each count the conversions they influenced, often the same ones, using attribution windows and modelling that favor themselves. Added together, platform-reported results routinely exceed what the business actually recorded.
Good measurement doesn't pretend to be perfect. It combines clean platform tracking, first-party data and occasional controlled tests into a picture that's accurate enough to make budget decisions with confidence.
What we do
What's included.
The work itself, in plain terms. Every engagement is scoped to what your accounts actually need.
-
Tracking implementation
GA4, Google Ads conversions, Meta Pixel and Conversions API, and server-side tagging where it adds accuracy, all set up to respect consent.
-
Conversion definitions
Agreeing what counts: a purchase, a qualified lead, a trial start or a first paid renewal, and passing values that reflect each one's worth.
-
Business-outcome reporting
Blended acquisition cost, contribution margin and payback reported alongside platform metrics, so channel results can be checked against the bank account.
-
Customer quality
The first purchase isn't the whole story. Where the data allows, we track refunds, repeat purchases, subscription retention and lead quality by source.
-
Incrementality
Holdouts, geographic tests and platform lift studies, where volume supports them, to estimate what advertising actually caused.
-
Acquisition economics
Working out what you can afford to pay for a customer, how quickly you need that cost back, and what that means for budgets and targets.
Inside the account
What it looks like in practice.
The structure, tests and decisions behind a well-run account. The numbered notes explain why each line is built the way it is.
What the platforms claim vs. what the business recorded
35% over-claim. Budgets set on platform totals would be funding conversions that happened once but were counted twice.
- Paid media spend
- $2.86M
- Revenue (business)
- $4.91M
- MER (blended)
- 1.72×
- New-customer CAC
- $104.76
- 90-day repeat rate
- 34%
- Meta incrementality (geo holdout)
- 0.71× reported
- Budget decisions use the business view (blended MER and new-customer CAC), with platform data steering optimization inside each channel.
- A holdout test showed the platform's reported conversions overstated true incremental impact, so its CPA target was set against the incremental figure, not the reported one.

How we think about it
Principles
-
Attribution is an estimate
Every model makes assumptions. We use several views and look for where they agree.
-
Blended numbers keep everyone honest
Total spend divided by new customers can't be inflated by double-counting.
-
Measure the customer, not just the conversion
A cheap customer who refunds or churns in the first month is an expensive one.

FAQ
Measurement questions.
Why don't our Google and Meta numbers match our actual sales?
Each platform claims credit for conversions it touched, using its own attribution window, and both include modelled conversions. The same sale is often counted by both. Comparing platform numbers with blended, first-party results shows how much of the reported total is overlap.
What's a good ROAS?
There isn't a universal number. The return you need depends on gross margin, repeat purchase, subscription retention and how quickly you need to recover acquisition costs. We work backwards from those economics to set targets.
Do we need server-side tracking?
Often it helps. Browser restrictions and ad blockers mean browser-only tracking misses conversions, and the Conversions API and enhanced conversions recover some of that signal. Whether full server-side tagging is worth it depends on your volume and setup.
