Case study
26% more conversions, from data alone.
A performance agency · Last updated: July 2026
A performance agency was making budget decisions on numbers that looked precise and were quietly wrong. We rebuilt the tracking underneath their client accounts, and the campaigns didn’t change, but the results did.
The situation
Strong campaigns, shaky numbers.
The agency ran strong campaigns for a portfolio of ecommerce and lead-gen clients. Reporting came from GA4 and platform dashboards that rarely agreed, and every monthly review started with a debate about which number was real.
What was broken
Signal stripped before it counted.
Browser restrictions and ad blockers were stripping a large share of conversions before they were ever counted. Enhanced conversions were half-configured. The platforms were optimizing budget on a fraction of the true signal.
What we fixed
Configuration, per client, verified.
A first-party server-side setup, configured for each client rather than copied between them
Enhanced conversions and CAPI verified live against the existing numbers before switchover
A single source of truth in BigQuery, so every client report finally reconciled
The results
What recovering the data was worth.
38%
of client traffic affected by tracking prevention, now recovered
+26%
average uplift in measured conversions
14 hrs
saved per project on manual reporting
What became possible
Clean data opens doors guesswork can’t.
Customer match
Complete first-party data made audience match usable again across platforms.
Lead scoring
Clean events fed a lead-quality model instead of guesswork on form fills.
POAS, not just ROAS
Real margin data flowing through meant optimizing on profit, not revenue.

We map where conversion data goes missing across your client accounts, and show what recovering it would be worth. Not a demo, not a sales call.
