For e-commerce from 40,000 euro of ad budget a month

If you doubled your ad budget tomorrow, would you know what happens to your margin?

I install the system that checks your account every day and judges every ad every week, inside limits agreed in advance, and I make the calls that follow. No promise about return. What you buy is a check a day, a limit that holds, and a decision a week.

What I put on the screen in the call

  • Ads Manager next to Shopify and Klaviyo, from a real account with the name taken out.
  • The same ad across 3, 7 and 14 days, and why winning in one window still says nothing.
  • How many purchases an ad needed before I judged it, and which ad stayed live that week because of it.

Who this is and is not for

Better now than after the invoice, and better now than after the first call.

Yes

  • You sell outside your home market, or you are seriously working on it.
  • You spend around forty thousand euro a month or more on ads.
  • Your margin per order is positive after shipping, returns and payment costs.
  • You want to understand the decisions yourself, not just receive a report.

No

  • You are looking for a creative agency. The pool of concepts comes with it, the production does not.
  • You want software you configure yourself. You will be cheaper off elsewhere.
  • Your margin per order is negative. More budget only makes the loss faster, and we start there.
  • You want a guaranteed return. That does not exist, and whoever promises it is selling you something else.

In the past twelve months I have not

This is not modesty. It is the list the system is built on.

Who does this

Pieter Van der Auwera, through Ad Astra in Antwerp. Eight years in performance marketing, with over a hundred million euro of managed ad budget across more than twenty brands in e-commerce and lead generation. Not an agency and not a team: one operator with a system, which is why only a limited number of accounts run at a time.

This is not a tool, and not an agency

Automatic pausing and budget changes are not an invention. Meta and Google ship them for free inside their own managers, and there are tools selling them from a few tens of euro a month. The difference is not the automation but the calibration: none of those layers enforces a volume or significance threshold, so anyone setting a rule gets rules that fire too early. My work is calibrating those limits against your real order value, maintaining them, and making the call that follows. If you want to run that yourself, a tool is cheaper, and that is an honest answer.

What gets installed on your account

Daily breakage check

Disapprovals, delivery that stopped, billing problems and spend spikes. Silent when everything is fine.

Weekly judgement

Every ad across 3, 7 and 14 days against your own benchmark, with a volume gate that blocks false winners.

Budget guard

Pacing on the measured run rate against a monthly ceiling agreed in advance, and never more than twenty percent change per week.

Creative rotation

The weakest ad out, a reserve in, inside six fixed limits. Your best ad is never touched.

Hook mining

Language from your own brand universe and form from sectors outside your category, so successors are always ready.

Competitor scan

Monthly, what changed at the brands you run into, in ads and in search.

How it runs

  1. A thirty minute call, free. I look into your account, you hear what I see. One page gets signed first, setting out what I will not do: copy nothing, keep nothing, change nothing.
  2. A two week diagnostic, 3,500 euro one off. Funnel, measurement stack, margin per order and efficiency per market, plus a ninety day plan. If we find no fivefold room to improve, you do not pay.
  3. A two week installation, 4,500 euro one off. Server side measurement, margin per order fed back to the platforms, and the six components configured on your own benchmarks and ceilings.
  4. Monitoring, ongoing: 2,500 euro a month, or 7 percent of the managed ad budget if that is higher. The check every day, the judgement every week, thirty minutes together every week. Three months minimum, monthly after that.

Why the places are limited

Two installations at a time and six running accounts at most. That is not a sales trick but arithmetic: an installation takes two intensive weeks and a running account about an hour and a half a week. Above that I can no longer guard the limits I promise, and then the system is worth exactly as much as a tool nobody maintains.

Frequently asked questions

Does Meta not do this for free with automated rules?

Partly, yes. Meta and Google can both pause and change budgets automatically, at no cost. What they do not do is enforce a volume or significance threshold: you set a rule yourself and it fires on the raw numbers you give it. That is exactly how you end up pausing ads that happened to have a bad week, and scaling on three coincidental conversions. The difference is the calibration against your real order value, and keeping it maintained.

What does it cost?

The diagnostic is 3,500 euro and the installation 4,500 euro, both one off. Monthly monitoring is 2,500 euro or 7 percent of the managed ad budget, whichever is higher, plus a share of revenue growth above a baseline we agree before the start. At forty thousand euro of spend a month you land on the floor of 2,500 euro.

What if it does not work?

On the diagnostic: if we find no fivefold room to improve, you do not pay. On the monitoring we agree a gate together in week two, for instance that no ad runs more than fourteen days above its cost threshold without an intervention. If that gate stays shut through something on my side or the system's, the monthly fee does not run until it is resolved.

Does the system touch my budgets by itself?

No. It measures, judges and proposes; I decide and execute. Two components may switch an ad on or off inside fixed limits, and those limits are written down: never below two live ads per ad set, never your best ad, at most one swap per ad set at a time. The system never touches budgets on its own.

What happens to my data?

Before the first call you sign one page setting out what I will not do: copy nothing, keep nothing, change nothing, and no sub-processor touches your data. If an engagement starts, a full data processing agreement follows with the sub-processor list in it. The working files hold aggregated figures only, never names or addresses of your customers.

Do you replace my current agency?

Not necessarily. At many brands this runs alongside as a second, independent layer: you get a number you can read back instead of a report you have to believe. If that shows the agency could do better, that is your conversation and not mine.

Thirty minutes tells you whether it fits

No deck and no proposal in that call. I look, you hear what I see, and after that you know whether a paid diagnostic makes sense. If it does not fit, I will say so in that same call.
