Selected work

Performance results and measurement work.

The point is not a wall of impressive numbers. It is showing what changed, how it was measured and where the comparison has limits.

English case notes

Selected cases, with the context behind the numbers.

These are concise English versions of the public source cases—not polished success stories with the awkward details removed.

ParkDa24 · Airport parking

From untracked advertising to value-based decisions

Starting point

€172,116 was spent in six months without working booking or revenue tracking. Sales may have happened; the account simply could not connect them to advertising.

What changed

Real bookings and booking values became the primary signal. Brand and new demand were separated, and budgets began following value and seasonality rather than clicks.

What the numbers cover

Across the following 25 months: 8,947 tracked bookings, €827,917 gross booking value, 2.5× ROAS and €37 per booking. The periods differ, and booking value is not margin.

Better signals before broader automation

Starting point

A large wedding-ring catalogue had sharply different margins and conversion rates. Treating every product alike gave the bidding system the wrong economic picture.

What changed

Server-side measurement, Consent Mode and enhanced conversions strengthened the purchase signal. A 90-day script grouped products by performance so budgets followed evidence.

What the numbers cover

The historical account view reports €424,000 in Google Ads-attributed revenue and 1,200 tracked purchases. A separate recent 90-day view shows €138,588 tracked revenue on €23,309 cost (5.9× ROAS) and 599 orders. Attribution does not prove how many purchases would have happened without advertising.

A faster landing-page workflow without rebuilding the useful parts

Starting point

Seasonal campaigns needed focused pages, but page production, forms and the existing email automation were too tightly coupled. New tests became slower and larger than necessary.

What changed

The consultation separated landing-page production from the email automation worth keeping. Direct upload, domain connection and team handoff were explained live.

Status after the consultation

The team left with a clear route for the next landing page. The later rollout and its effect on conversions, leads and revenue were outside this consultation.
