A €300 campaign that sold €180,000 of equipment
Three dental clinics bought CBCT scanners worth €180,000 in total after a Facebook campaign that cost €300. The ads were simple. The audience did the work: almost everyone who saw them could actually buy the product.
I ran marketing for a dental equipment distributor at the time. Here is how the campaign worked, and how any manufacturer with a small, known pool of buyers can repeat it.
Why cold audiences fail for expensive B2B products
Before this campaign, our ads went to broad, cold audiences: people interested in dentistry, students, anyone who followed a clinic page. They brought cheap clicks and almost no sales.
The problem is arithmetic. A CBCT scanner costs €50,000–70,000, and only clinic owners buy one. In a broad audience, most of the budget reaches nurses, students and patients, who will never place that order.
For a product like this, the buyers already exist and can be listed by name. So the ad only has to reach them, several times, while they are thinking about an upgrade.
Building the buyer list from a public registry
In Ukraine, private dental practices are registered as businesses with an activity code for dental practice, and the public register lists their contact phone numbers. We filtered the register by that code, cleaned the list, and uploaded the numbers to Meta as a custom audience.
The result was an audience made almost entirely of the people who run dental clinics. No interest targeting, no lookalikes.
Most markets have an equivalent:
- UK: Companies House filtered by SIC code 86230 (dental practice activities), plus the General Dental Council register
- US: the federal NPI Registry, which lists dentists and practices by taxonomy code
- EU: national business registers filtered by NACE code, plus professional chambers
- Any industry: trade association member lists and exhibitor lists from the main trade show
One caution: the rules on using contact data for ads differ by country. In the UK and the EU, check your lawful basis under GDPR before you upload a list, and keep a record of where the data came from.
One creative, one product truth
The ad was a 3D render of the new scanner, built around the two things a clinic owner notices first: the large sensor and the AI features. No discount, no generic "upgrade your clinic" line.
With an audience this precise, the creative only has to show people who already know the category what is new, in one glance. Clever copy matters far less than getting the one product fact right.
Results
The campaign cost €300 and brought three buyers, €180,000 in scanner sales.
| Buyer | Scanner price | Where the deal came from |
|---|---|---|
| Clinic 1 | €70,000 | First run; bought almost immediately |
| Clinic 2 | €60,000 | First run; closed later by the sales team |
| Clinic 3 | €50,000 | A rerun of the same ad; a different model |
The third sale came from rerunning an ad that had already worked, not from a new campaign. We also connected Facebook campaigns, the CRM and the accounting system, so each campaign showed profit rather than leads.
How a manufacturer can copy this
- Count your real buyers. If the people who can sign the order number in the thousands, not millions, you can probably list them.
- Find the public register that names them: a business register by activity code, a professional register, a trade association or a trade show exhibitor list.
- Build the list and upload it as a custom audience. Exclude current customers, or give them their own message.
- Make one creative around the one thing your buyers notice first about the product.
- Spend small and judge by deals, not clicks. A few hundred euros is enough to learn whether the audience is right.
- Rerun what sold before you build anything new.
- Connect campaigns to closed deals, so you know which spend actually paid.
When this does not work
- Your buyers are not in any register: consumers, or a business audience too broad to list.
- The list is too small for the ad platform to deliver to; very small custom audiences may not run at all.
- Data protection rules in your market do not allow it without consent.
- Sales cannot follow up fast. A precise audience brings few leads, and each one counts.
