Set your budget from capacity and acquisition cost, not a percentage of revenue: the number of extra customers you can serve next month, multiplied by what you can afford to pay for each one. Below roughly $1,500 to $2,000 a month, most local campaigns can't generate enough conversions for Meta's delivery to learn, and results stay erratic.
The full methodA contractor's ceiling cost per lead is the share of gross margin you'll spend to win a job, divided by the number of leads it takes to book one. For example, a $900 job with $360 of margin, spending 20% to win it, at one booking per three leads, supports about $24 per lead.
Work out yoursA clinic should price acquisition against 12-month margin rather than the first visit, adjusted for how many booked patients actually show up. In a worked example — $350 first-visit margin, about 2.5 visits a year, spending 25% of that margin to acquire, with half of leads booking and 70% attending — the clinic can afford roughly $75 per lead.
The clinic mathFacebook and Instagram ads are usually the better starting point for aesthetic, wellness and weight loss clinics, because they reach people before they search; Google Ads are better for urgent, search-driven services, because they capture people already looking. For high-consideration treatments, running both works best.
The comparisonFacebook ads usually produce leads within the first couple of weeks, and the first month is largely Meta's delivery learning who converts. Performance typically stabilizes after that, provided the budget is large enough and the campaign isn't being edited constantly.
Clinic ads are most often rejected under Meta's Personal Attributes policy, which bans ads that imply knowledge of the viewer's health — usually second-person copy like "Struggling with your weight?". The other common causes are before-and-after images, naming prescription drugs, and claims on the landing page the ad links to.
The five causesMostly not: Meta prohibits side-by-side before-and-after images for weight loss and anti-aging treatments in health and wellness ads. The workable approach is to sell the consultation in the ad and show genuine, consented, unaltered results on your own landing page.
Both rulebooksNaming prescription drugs like semaglutide or tirzepatide in Facebook ads is restricted, and enforcement on GLP-1 medications has been strict and inconsistent. Clinics do better advertising the medically supervised program — labs, monitoring and the clinician — rather than the drug itself.
Copy that gets approvedWhen Facebook ads stop working, check in this order: changes in your own business (like slower lead response), broken tracking, ad frequency in a small local audience, rising competition or seasonality, an offer that's gone stale, and only then the creative. Changing one thing at a time is the only way to find the cause.
The diagnostic orderThe Meta Conversions API sends conversion events from your server to Meta instead of relying only on the browser pixel, which ad blockers and browser privacy features block for a meaningful share of visitors. Most advertisers should run both, sharing an event ID so Meta counts each conversion once.
