Do Billboards and Radio Ads Work for Medical Practices?

A pediatric dental owner called us a couple of years back, half excited and half nervous. A billboard company had pitched her a spot on the busiest road in town, right by the school exit. Forty thousand cars a day, they said. She wanted to know if she should jump on it before someone else grabbed it. Good instinct to ask first, because the real question was not "is forty thousand cars a lot." It was "how many of those drivers will I be able to prove walked through my door." The honest answer was none. Not few. None that she could ever count.

So let me answer the question owners ask us all the time, plainly. Do billboards and radio ads work for a medical practice? They can build a little awareness, and they are very hard to measure, and for most single location practices the same money spent online brings patients you can actually track. That is not a knock on traditional media. It is about what a small practice can afford to not be sure about.

Billboards and radio sell awareness, not booked patients

There is nothing magic or broken about out of home advertising. Big brands use it for a reason, and the industry numbers look healthy. Outdoor advertising carries one of the lowest costs to reach a thousand people of any major channel, somewhere around two to seven dollars, and the Out of Home Advertising Association of America likes to point to strong average returns across large campaigns. You can read the kind of figures the industry cites in this outdoor advertising ROI roundup.

But notice what that sells: reach and awareness. It keeps a name in front of a lot of eyes. That is gold for a soda brand that wins by being the first thing you think of at the cooler. A medical practice does not win that way. Nobody picks a surgeon because the name felt familiar on the commute. They pick when they have a need, and at that moment they research. Awareness is the easy part. Trust and proof are the hard part, and a board on a pole cannot give either.

Radio has the same shape. It reaches a wide local audience cheaply, but it sprays your message at everyone driving at 8am, the vast majority of whom do not need a dermatologist or a knee specialist today. You pay to reach all of them to find the handful who do. For a brand with a giant budget, that waste is acceptable. For a practice counting every marketing dollar, it is the whole problem.

The part nobody can measure is the part that matters

Here is the line we end up saying on almost every call about traditional media. If you cannot measure it, you cannot manage it, and a practice cannot afford to spend blind. With a billboard you will never know if the new patient on Tuesday saw your board or found you another way. The industry knows this is the weak spot. As one breakdown of billboard advertising statistics puts it, traditional boards do not allow precise engagement metrics, which makes it tough to know who actually responded.

And here is the twist that makes the billboard even riskier. The few people who do notice it almost never act on the board. They reach for their phone and search your name. A 2025 patient choice survey found that around 77 percent of patients begin their search for care on Google, and roughly 60 percent of healthcare related searches now happen on a mobile device, according to reporting on how patients find healthcare providers. So your expensive board is really just a prompt to go Google you. If what they find is a thin listing, a 3.2 star rating and a website that takes seven seconds to load, you paid to send a curious patient straight to a wall. We wrote about that exact leak in why your practice is not showing up on Google.

Where the same money works harder

Picture two practices with the same modest budget. One buys a billboard for the quarter. The other spends it where patients are already raising their hand. By the end of the quarter, the first owner has a nice photo of her name on a road and a vague hope. The second can tell you how many people called, how many booked, and what each new patient cost. One of those owners can make next quarter smarter. The other is guessing again.

Here is the order we actually put practice money in, because it captures demand instead of just shouting into traffic:

• Your Google Business Profile and reviews first. This is the free storefront most patients judge you on before they ever reach your site. Polishing it and building steady reviews is the highest return move in local healthcare. Start with your Google Business Profile and getting more reviews.
• A website that loads fast and books patients. All the traffic in the world is wasted if the page is slow or the only option is a form nobody answers. See what a practice website actually needs.
• Search ads aimed at real intent. When someone types "pediatric dentist near me," you can be right there, and you can count every click, call and booking. That is the opposite of a billboard. More in Google Ads for medical practices.
• Social and reactivation. Show up where patients scroll, and bring back the people already in your system. The cheapest patient is the one you already treated, covered in reactivating past patients.

So when does traditional advertising make sense?

It is not never. Once your online engine is humming, your listing strong, reviews flowing, website converting, ads bringing trackable patients, a billboard or a radio read can reinforce a name people are already starting to recognize. At that stage you are not relying on it to fill the schedule, you are layering brand on top of a machine that already works. Larger groups with multiple locations and real brand budgets get the most out of it, because they can absorb the waste and they benefit from blanket recognition across a metro.

The mistake is doing it backwards: buying awareness while the path that turns awareness into a booked patient is broken. That is the same trap we see with practices that lean too hard on word of mouth and never build a system, which we dug into in when a practice is too dependent on referrals. Hope is not a channel, and neither is a billboard you cannot measure.

How EtherealMinds thinks about this

We work only with healthcare practices in the United States, and we will be straight with you on the first call: we are not going to talk you into a billboard. We would rather put that money where you can see it work. Our whole approach is building a patient acquisition system that captures people in the moment they are searching, then proves what it brought in, so every quarter you spend a little smarter instead of guessing. That means a website that converts, a Google presence patients trust, ads tied to real intent, and the follow up that turns an inquiry into a booked visit.

If a measurable offline test ever makes sense for your market, we will help you set it up so it actually reports back. But the foundation comes first, because a billboard pointing at a weak online presence is just an expensive way to remind people to choose someone else. Build the engine that books and counts patients, and the question of billboards mostly answers itself.

So, do billboards and radio ads work for a medical practice? For awareness, a little. For patients you can prove and afford, almost always less than the same money spent where people are already searching for you. Put the dollars where you can watch them turn into booked appointments. The road sign can wait until you can afford to not be sure.
