I check whether the numbers you make decisions on are real. Most teams scale on ROAS that double-counts, conversion tracking that misfires, and a GA4 setup nobody fully trusts. The measurement audit replaces faith with fact.
What you get
- A MER versus ROAS reconciliation: the honest top line
- A conversion-tracking and GA4 configuration review
- A server-side tagging assessment (sGTM, Tag Gateway)
- An incrementality view: which spend is actually additive
Proof anchor
Conversion-tracking diagnosis for a London private healthcare client that exposed mis-attributed spend, and a MER-led doctrine carried across a £20m+ portfolio.
