Goal
At which point do you still make money on every additional euro of revenue?
More revenue can be bought. Whether any of it sticks is decided in three places: the number your bids are based on, the separation of brand and new business, and whether a channel still has demand left to find.
What we do: We move your bidding from revenue to contribution margin, separate brand and existing customers from new business and measure with control groups what a channel adds; you pay for growth that would not have happened without you.
Why this is hard right now
Most ad accounts are steered on revenue, not on contribution margin. That goes unnoticed for a long time because the metric looks good. It becomes visible in one place: when every conversion carries the same value even though contribution margins differ by multiples between product groups, a value-based bidding strategy buys volume and reports it as value.
The second reason is the mixing of brand and new business. A blended ROAS can look healthy because brand queries carry it; strip them out and often little new business remains. The same pattern shows when the share of conversions from an automated campaign rises while total revenue stays flat. The campaign is then shifting revenue, not creating it.
The third reason is banal and still rarely said out loud: search campaigns hit a ceiling because demand is finite. From that point on, a higher bid buys no additional business, only a higher price for the same.
The questions we work through with you
Does your bidding steer on revenue or on contribution margin?
How you can tellIn the account, every conversion carries the same value even though contribution margins differ substantially. A target ROAS on that basis optimizes for volume. A second sign is double-counted conversions, say the same order recorded as a purchase and as a thank-you page view: the metrics then look better than they are, and the automation bids too high.
What we doWe review conversion actions, values and double counting before touching a single setting. Margin, returns and customer value belong in the number your bids are based on. Only then does the choice between target CPA and target ROAS settle itself: target CPA as long as all conversions are worth roughly the same, target ROAS once they are not and the differing values are actually passed to the platform.
How much of your growth would have happened without any ad pressure?
How you can tellThe share of conversions from one campaign rises while total revenue stays flat. Or the share of existing customers among your conversions is high while nothing changes in the business. Both are signs that budget is buying demand that would have arrived anyway.
What we doWe report brand, existing customers and new business separately and pull existing demand out through exclusions and dedicated campaigns. For the question of what a channel adds, attribution alone is never enough: a channel can look good in every attribution model and still be doing nothing but collecting. Only a comparison against a group that did not see it can tell.
Are your high-margin products subsidizing the low-margin ones?
How you can tellThe report shows a cost-revenue ratio that is true for no single product. The most common cause is one asset group for the entire range: the average hides that one half is carrying the other.
What we doWe cut asset groups by margin, availability and purchase occasion instead of by channel or gut feeling, and each group gets its own audience signals instead of a copy. As soon as two product groups have different margins or different audiences, they do not belong in the same group.
Do you know what a new customer is worth over time, and do you steer by it?
How you can tellThere is exactly one customer list, with no distinction by value, recency or product range. That rules out both exclusions and weighting, and the question of which customer group deserves the budget cannot be answered.
What we doWe cut segments by customer value, recency and product range and bring them into delivery via Customer Match. Google accepts email addresses, phone numbers, postal addresses and customer IDs for this, transferred hashed, with a maximum membership duration of 540 days and at least 100 updated users. Your legal team assesses the legal basis; we implement the result and automate the refresh so the lists do not go stale.
How do you notice that a channel has hit its ceiling?
How you can tellA higher bid no longer brings additional volume, and cost per conversion rises without anything changing in the market. Demand is exhausted, not the account setup.
What we doThen the next step sits before the search. Demand Gen reaches people on YouTube including Shorts, in Discover, in Gmail, on Maps and across the Display Network, even when they are not searching right now. A channel like that is measured with control groups or by deliberately holding out audiences, not by last-click attribution: whoever creates demand rarely shows up as the last click.
The expertise we combine for this
- SEA / Paid SearchSteers search and Performance Max campaigns on values that reflect your business, and keeps brand and new business separate.
- Product Data & ShoppingMakes sure your products enter the auction at all instead of failing on required attributes or price mismatches with the landing page.
- Measurement & AttributionDefines the number your steering runs on, and separates day-to-day attribution from the question of what a channel truly adds.
- Tracking & AnalyticsBrings your own customer data into delivery and closes the gap between deals in your business systems and reported conversions.
- Creative & ContentDelivers on the ad's promise on the landing page, so an expensively bought click gets a chance.
And the technology to match
Which revenue hangs on which measure rarely lives in one place. Marketing Intelligence brings the numbers from all channels together in one logic, so margin and customer value show up where decisions are made, not just in the quarterly report.

Frequently asked questions
Target CPA or target ROAS?
Target CPA as long as all conversions are worth roughly the same. Target ROAS once they are not and the differing values are actually passed to the platform. Without that handover, target ROAS optimizes for volume too.
How do I tell that a campaign is merely shifting revenue?
By its share of conversions rising while total revenue stays flat. A second sign is a healthy blended ROAS that shrinks to little once brand queries are stripped out.
Why is an attribution model not enough to steer profitability?
Because attribution says who gets credit for a conversion, not whether it would have happened without the channel. Google Ads today still offers last click and data-driven attribution; the older models first click, linear, time decay and position-based have been retired. The question of incremental contribution takes a comparison against a group that did not see the channel.
How many asset groups does Performance Max need?
As many as your range has distinct purchase occasions. Any general number would be a guess. The usable yardstick is a different one: as soon as two product groups have different margins or different audiences, they do not belong in the same group.
What do I do once search is maxed out?
Create demand instead of paying more for the demand that exists. Demand Gen serves YouTube including Shorts, Discover, Gmail, Maps and the Display Network for that. What matters is settling measurement first: with control groups, not with the last click.
How long until a bidding strategy change shows results?
That depends on the number of conversions in the account; any fixed duration would be a guess. The usable yardstick is whether cost per conversion has settled over several weeks. Which is why we schedule changes for quiet weeks and never several at once.
