    How it works

    Audit

    Before we touch anything, we go through your account. We look at where your budget is going, how your campaigns are structured, and whether the tracking is correct.

    Strategy

    From there, a plan built around your margins, products, and what the data actually shows.

    Launch

    We turn the campaigns on once we know exactly what's being measured.

    Scale

    Daily adjustments based on what the data shows.

    Client result

    Same budget, 250% more profit

    A Dutch e-commerce retailer was hitting their ROAS targets every month, but profits weren't growing. Their campaigns optimized for revenue, not margin. By passing actual margin values to Google instead of revenue, we shifted budget toward the products that actually made money.

    Key insight

    ROAS was at 300%, but profits weren't growing. Give the algorithm the wrong input and it will optimise the wrong output.
