Facebook dental leads not answering or turning up? Diagnose it in the right order

The symptoms

"The leads are rubbish" covers several different problems. Naming the exact one tells you where to look.

Write down which symptom you're seeing, and for how many leads, before changing anything. "Most of them" isn't a diagnosis. "Twelve of the last thirty didn't answer after two calls" is.

The causes

Here's the order I diagnose in. It starts with the cheapest checks and ends with the ones that need a build.

1. The numbers. If nobody records which leads were called, answered, booked and attended, you can't tell a lead problem from a follow-up problem. This is the first fix every time, and it costs nothing but a spreadsheet column.

2. Speed. A lead called within minutes is a different lead from the same person called the next afternoon. If first calls are slow, fix that before touching the ads.

3. The form. Meta's default instant form type, More volume, is built to be quick to submit on a phone and to generate more leads.¹ Quick to submit also means quick to forget.

4. The offer. An ad that leads with a free or heavily discounted offer attracts people who want the free thing. That's a creative decision, and it can be changed.

5. The signal. Meta's performance goal decides who it looks for. "Maximise number of leads" shows your ad to people most likely to share their contact information. "Maximise number of qualified leads" shows it to people most likely to convert after sharing it.² If the goal is leads, Meta is doing its job when it finds people who fill in forms. It was never told to find people who turn up.

Advantage+ audience compounds this. Meta's AI finds the audience using signals such as past conversions and Pixel data.³ Feed it form fills and it finds more form-fillers.

Fixing the form

The form is the quickest thing to change inside Meta. Each fix below trades some volume for some quality.

Good qualifying questions are easy to answer and useful to reception: when they'd like to start, whether they'd like to hear about spreading the cost, the best time to call. Don't turn the form into a medical questionnaire.

Sometimes the fix is to leave the form altogether. When a treatment needs explaining, a landing page can outperform any form on booked consultations. That comparison is on lead forms versus landing pages.

Fixing the signal

The lasting fix is to tell Meta what a good lead looks like. That means sending lead stages back from the practice. I send two: consultation booked and consultation attended.

Meta's qualified-leads performance goal uses those later events to find people more likely to convert. From April 2026, Meta says the goal is no longer available for new campaigns without a Conversions API integration, and existing campaigns are affected from August 2026.² The Conversions API is how your own systems send events to Meta, server to server.

Dentistry adds a limit. Meta prohibits sharing health information through its business tools, including information about medical procedures and treatments, and that applies to event names and custom data.⁵ So the events describe the stage, not the treatment, are hashed, and go only for patients whose explicit consent is recorded. "Consultation attended" tells Meta enough. "Implant consultation attended" tells it something it shouldn't have. Meta can also restrict mid and lower-funnel events for a health business, which can block even these two.⁶ The build, and the health-data limits in detail, are on the Conversions API for dental practices.

Once the signal is working, give it time. Meta needs a run of those later events before it can learn from them, and a lead from this week may not book for a fortnight.

Fixing intake

A good lead, badly handled, becomes a bad lead. Intake is the practice's job, but it's part of the same system, and it's where a lot of Meta spend is lost.

What good intake looks like:

• One named person owns new leads each day, with cover for breaks and days off.
• The first call happens fast, while the patient still remembers the ad. The detail is on speed to lead in dental practices.
• Several attempts, at different times, before a lead is marked as unreachable.
• Every outcome is recorded: answered, booked, not interested, wrong number, never reached.
• The source is recorded so Meta leads can be counted separately.
• Bookings are confirmed with the date, time, what to expect and any fee, so attendance isn't left to chance.

My part is the measurement: I make the lead stages visible, per treatment and per ad, so the report shows where leads are lost. If the numbers say leads answer, book and attend, the ads are doing their job. If they say leads go unanswered, no change to the campaign will fix it.

If you're not sure which of these is your problem, email [email protected] with what reception is seeing and roughly how many leads it applies to. I do a first look for free, from the outside, at your ads and the form or page behind them, and reply with what I find.
