A med spa's blended cost per lead is a real number and a mostly useless one, for the same reason a dental practice's blended cost per lead hides implant economics inside general checkup numbers. We've made this argument for dental practices before, and it applies to med spas with even more force, because the treatment categories underneath a typical med spa account don't just cost different amounts to acquire. They're different kinds of purchases entirely.
Most med spas run some mix of three broad categories: injectables (Botox and filler), body contouring (CoolSculpting, laser treatments, and similar non-surgical or minimally invasive fat and skin procedures), and skincare (facials, peels, and similar lower-commitment services). Average them into one cost-per-lead or cost-per-booking number and you get a figure that's technically accurate and tells the client almost nothing about which part of the account is actually working.
Three categories, three different economics
Start with ticket size. The American Society of Plastic Surgeons' published cost data puts the average cost of a botulinum toxin treatment at $435, hyaluronic acid filler at $715, non-hyaluronic acid filler at $901, and lip augmentation with filler at $743. Liposuction, the surgical anchor point for body contouring, averages $4,711 based on surgeon's fee alone, before anesthesia, facility, or other costs. That's more than a 10x spread between the cheapest injectable category and a body contouring procedure, sitting inside the same med spa account and, in a lot of reports, the same blended average.
the spread between an average botulinum toxin (Botox) treatment and an average liposuction procedure, per the American Society of Plastic Surgeons' published cost data. A blended cost-per-booking number can't show a client which one they're paying for.
Frequency runs in the opposite direction. Botox typically wears off in three to four months, which means a satisfied injectable patient is a repeat booking on a predictable cycle, often multiple times a year. Body contouring is closer to the opposite: it's a bigger, more considered purchase that a patient researches, thinks about, and books once, sometimes as a multi-session package, rarely more than once every year or two. Skincare sits somewhere in between, lower ticket than either injectables or body contouring but often the most impulse-driven of the three, and frequently sold as a recurring membership rather than a one-off booking.
Why blending them produces a misleading number
Put those three categories into one weekly cost-per-booking average and the number stops meaning anything specific. A practice running mostly injectables with a small body contouring push will show a healthy blended number most weeks, because injectables book fast and cheap, and the slower, more expensive body contouring campaign gets absorbed into an average that still looks fine. If that body contouring campaign is actually performing badly, wasting spend on the wrong audience or bidding into keywords it can't win, the blended number won't show it. It'll keep looking acceptable right up until someone finally checks the campaign in isolation.
Flip it around and a practice running a body contouring push during a slow injectable month will show a blended number that spikes and looks like a crisis, when the body contouring campaign is actually performing exactly as expected for a category with a longer sales cycle and a much higher lifetime value once repeat visits and referrals are factored in. Either direction, the blended average hides the real story instead of telling it, and a client who only sees the blended number has no way to tell which situation they're actually in.
Reporting that doesn't flatten your categories into one number
NarrateIQ breaks results down by campaign and category in every report, so an injectable push and a body contouring campaign never get averaged into a number that hides which one actually needs attention.

The fix is the same one that works for dental and every other multi-procedure vertical: report cost per booked consultation by category, not as one house-wide average, and set a separate target for each. Injectables should be measured against an injectable-specific target. Body contouring should be measured against its own, with the understanding that it will look more expensive per booking and be worth it anyway once the ticket size is factored in. Skincare gets its own line too, especially if it's driving membership signups rather than one-off visits, since a membership's value compounds in a way a single facial booking doesn't.
This connects directly to the case for anchoring med spa reports on cost per booked consultation in the first place. Booked consultation is the right unit to measure. Splitting it by category is what makes that unit trustworthy, because a category-blind number is exactly the kind of report that leaves a first-time med spa client confused about whether their account is actually working, even when it is.
This doesn't require new data, just a different rollup
None of this needs a bigger reporting effort. The campaign-level data already sitting in Google Ads and Meta Ads is broken out by campaign, and campaigns are usually already organized by treatment category if the account was built with any structure at all. The work is in how that data gets rolled up before it reaches the client, not in collecting anything new. Unrolling a blended average into three category-level numbers is a formatting decision, and it's the difference between a report a med spa owner glances at once and one they actually use to decide where next month's ad budget goes.
If you're managing med spa clients and still sending one blended cost-per-booking number a week, it's worth checking what's actually hiding inside it. Given the spread between a $435 injectable visit and a $4,711 body contouring procedure, there's a good chance it's three numbers, not one.
