Let us start with the number that changes the whole question. In marketing science there is a well known finding called the 95:5 rule, laid out by Professor John Dawes at the Ehrenberg-Bass Institute for Marketing Science. It says that at any given moment, only about 5 percent of your potential customers are actually ready to buy. The other 95 percent are out there, but they are not in the market this week.
Healthcare is not a soda or a car, but the logic holds even harder here. Someone does not wake up planning to need a dermatologist. Their skin flares up, or a mole changes, or their kid needs a sports physical, and suddenly they are in that 5 percent, typing "dermatologist near me" into their phone. If your ad is running that day, you are in the running. If you switched it off to save money because last month was busy, you are invisible on the exact day it mattered.
Demand does not wait for your slow season
The reason on and off advertising fails is that patient demand is not one big wave you can see coming. It is thousands of tiny, private, unpredictable moments spread across the whole year. A study from Penn Medicine researchers found that people's health related internet searches roughly doubled in the week before they showed up at an emergency department. People search right when the need hits, not on a predictable schedule you can plan around.
Zoom out and it is even clearer. Health topics make up close to 5 percent of everything typed into Google, every single day of the year. There is no month where nobody is looking for care. There are only months where you chose not to show up.
This is the trap of running ads only when you feel slow. By the time your schedule looks empty, the patients who could have filled it were searching two, three, four weeks ago, and they booked with whoever answered. New patient ads have a delay built in. You are not filling next week. You are filling next month. Start advertising the day you notice a gap and you are already behind.
The hidden cost: the algorithm forgets you
Here is the part almost no owner knows about, and it is the one that hits the wallet. Google Ads and Meta ads both run new campaigns through a learning phase. For the first stretch, the system is figuring out who to show your ad to, and results are rough and expensive. Once it learns, your cost per lead settles and drops. That learning has real value, and it is fragile.
When you pause a campaign and turn it back on later, you can throw that learning away. On Meta, an ad set left paused for more than about a week typically has to re-enter the learning phase when you restart it. Google works the same way: pausing and reactivating a campaign, or making big changes to it, can send it back to relearning from close to scratch. Even big budget swings do it. Change a budget by more than roughly 20 percent at once and you can trigger the same reset.
Read that back and the on and off habit looks worse than wasteful. Every time you flip the switch to "save money," you are not just going dark for a few weeks. You are paying the expensive tuition of the learning phase all over again when you come back. You save a little on the pause and lose more on the restart.
A quick story from the trenches
A men's health clinic came to us doing exactly this. Every December they killed their ads because the holidays felt slow and they wanted to protect cash. Every January they switched them back on and complained that leads cost twice as much and barely trickled in for the first few weeks. They blamed January. It was not January. It was the restart. The campaigns were relearning from zero every single year, in the exact window when guys make "get healthier" resolutions and go looking for a TRT clinic. We kept the ads on through the holidays at a low baseline instead, then turned the budget up in January. Their January cost per lead dropped by about a third, and they stopped losing the first three weeks of the year to a warm up they were paying for over and over.
So the answer is not on or off. It is always on, turned up or down
This is where we land after watching it play out across a lot of practices. The real choice was never "run ads" versus "pause ads." That is a false pair. The right frame is a dimmer switch, not a light switch. You keep a steady baseline running all year so you are always visible to that 5 percent who become ready each week, and so the platforms stay optimized. Then you turn the dial based on the season and your capacity.
- Keep a baseline on, always. Even a modest budget keeps your campaigns out of the learning phase and keeps you in front of people the day their need appears. Never go to zero.
- Turn the dial up before your busy season, not during it. If you know fall is your rush, raise the budget in late summer so the pipeline is full when demand arrives. Being visible right before the wave beats chasing it after.
- Trim, do not slam, in slow weeks. Move budgets down in steps of 15 to 20 percent, a week or two apart, so you never trip the learning reset. A gentle trim protects everything the campaign already learned.
- Advertise even when you are full. Full schedules empty out through cancellations, no shows, and finished treatment plans. A little always on spend means the gaps get filled before you feel them.
That last one trips people up, so it is worth saying plainly: staying visible when you are busy is not wasted money, it is insurance against the slow month you cannot see coming yet. We made the fuller case for that in why you should keep marketing when your practice is full.
Yes, seasons are real. Use them, do not obey them
None of this means seasonality is a myth. It is very real. Primary care and a lot of specialties see demand sag in January, when deductibles reset and patients delay care they will pay full price for, then build through the fall. Med spas and cosmetic services often spike before summer and again before the holidays. Every practice has a rhythm, and knowing yours is genuinely useful. We dug into one big one in is summer a slow season for medical practices, and into when people actually book in when do patients book appointments.
The difference is what you do with that knowledge. The owner who obeys the season turns ads off in the slow months and on in the busy ones, and gets punished twice for it. The owner who uses the season keeps a baseline running all year and leans the budget into the ramp before each peak. Same insight, opposite habit, very different cost per patient.
Where the on and off habit really comes from
Let us be honest about why practices flip the switch. It is usually not strategy. It is cash flow nerves, and a nagging suspicion that the ads are not really working, so cutting them in a slow month feels safe. Both of those are fixable, and neither is solved by pausing.
If ads feel like a cost you shut off when money is tight, that is a sign the spending is not tied to a clear return you can see. When you know what a new patient is worth and what one costs to acquire, advertising stops feeling like a bill and starts feeling like buying dollars for dimes, which you would never pause. We walk through those numbers in how much a practice should spend on marketing. And if the ads genuinely are not converting, the answer is to fix the leak, not to turn off the faucet.
The leak that makes people blame the ads
Here is the thing we see most often behind a practice that keeps pausing its ads: the ads were working, but the follow up was not, so it looked like the ads failed. Someone clicks your ad at 8pm, calls the office, gets voicemail, and books the practice that picked up instead. The ad did its job. It put a ready patient in front of you. The dropped call is what lost them, and then the ad took the blame and got switched off.
Running ads all year only pays off if every lead they produce actually gets answered. A paid lead is a person raising their hand right this second, and the window to win them is minutes, not days, as we covered in how fast you should respond to a new patient inquiry. That is why we pair every campaign with instant follow up through our AI receptionist, which answers the call or text the moment it lands, day or night, weekend or holiday, and books the appointment while your front desk is busy or closed. Keep the ads on and let leads slip and you get the worst of both. Keep the ads on and catch every one and the always on math works.
How EtherealMinds handles it
We run ads only for healthcare practices in the United States, and we do not do the on and off dance. We set a baseline that runs all year so your campaigns stay smart and you stay visible, then we map your specialty's real seasonal rhythm and turn the budget up ahead of each peak and gently down through the true lulls, always in small steps so nothing resets. We watch cost per booked patient, not clicks, and we make sure every lead gets answered in seconds so the spend actually turns into visits. It is all one connected engine, ads, follow up, website and reviews, which is the whole idea behind our patient acquisition system, and it pairs with the organic side we handle in social media management for healthcare.
So should you run ads year round or just in slow months? Run them year round, at a baseline you can sustain, and use the seasons to decide how hard to push, never whether to show up at all. The practices that stay on steadily collect the patients that the on and off crowd goes dark on. Be the one that is always there when the need appears.
