A buyer's guide for allergy and immunology clinics: how to judge an agency on booking testing visits and keeping immunotherapy patients on schedule.
Why a general healthcare marketing agency gets allergy care wrong
A lot of healthcare marketing agencies run the same playbook for every specialty: build a site, run some local ads, ask for reviews. That misses the actual problem in allergy and immunology, which is that most people never book a specialist visit at all. Instead, they keep buying more over-the-counter antihistamines for years, guessing at what triggers their symptoms instead of finding out. An agency that doesn't build your marketing around making the case that testing beats guessing is missing the biggest source of new patients in this specialty.
The second thing generalists miss is what happens after that first visit. A lot of allergy treatment is allergen immunotherapy, taken as weekly or monthly shots or as daily sublingual drops or tablets, over months to years, alongside ongoing asthma, eczema, chronic hives, food allergy, and immune-deficiency care. That course of treatment only works if the patient stays on schedule, and drop-off before treatment finishes is a well-known problem in this specialty. A marketing plan that stops at getting someone to book, and ignores keeping them on schedule, is only solving half the job.
The third issue is the patient mix. A large share of allergy and immunology patients are children, brought in by parents dealing with food allergy, asthma, or eczema. Those parents search anxiously and often, and a site or ad that doesn't make clear you see kids and can answer food-allergy and EpiPen questions loses that visit to whichever practice does say so clearly.
The first question: how will they sell testing over guessing?
Ask any agency directly: 'How would you convince someone who's been managing their symptoms with allergy pills for years to book a testing visit instead?' This is the single competence that separates a real fit for this specialty from a generalist. If the answer is vague, something like just running some ads for allergy care, keep looking.
A good answer talks about building pages and campaigns around the actual moment of doubt, like a symptom that over-the-counter medication isn't fixing anymore, rather than generic allergy-doctor messaging. It should also explain how they'd separate seasonal allergy content from food allergy, asthma, and immune-deficiency content, since those readers are searching for different reasons at different times of year.
Follow up with: 'How would you keep immunotherapy patients on schedule once they've started shots or drops?' An agency with a real answer will talk about reminder and follow-up email tied to the treatment calendar. An agency without one is only planning to fill your waiting room once, not keep your treatment plans on track over the months that follow.
Which channels book patients, and in what order
Google Ads is the fastest way to reach someone ready to book right now, whether that's a parent searching for a food allergy doctor near them after a scare, or an adult searching for allergy testing after another rough pollen season. These campaigns can start producing calls and booking requests within the first few weeks, and separating them by condition, seasonal allergy, food allergy, asthma, matters, since each search comes from a different worry.
Local SEO and your Google Business Profile decide who gets the call when someone searches for an allergist near them, since the map pack is usually the first thing a patient looks at. Reviews carry real weight here, since a parent choosing who tests their child for a food allergy is making a trust decision, not a convenience one. That kind of visibility takes longer to build than a paid campaign, but once it's there, it keeps sending you patients you aren't paying for with every click.
Planning for AI search matters just as much, since patients and parents increasingly ask an assistant directly for a recommendation, something like a good pediatric allergist nearby, and you want your clinic to be the name that comes back. Email and reminder follow-up matter more here than in most specialties, because immunotherapy only works if the patient keeps showing up, and a reminder system that catches a patient before they drift off their shot or drop schedule protects both the outcome and the revenue tied to that patient.
How allergy demand moves through the year, and what to track
Seasonal allergy search demand is genuinely seasonal, and it's common knowledge, tracked publicly by tools like Google Trends and pollen-count services, that interest spikes with spring tree pollen and again with late-summer and fall ragweed and mold. A clinic that only markets around those two spikes rides a boom-and-bust calendar the rest of the year. Food allergy, asthma, chronic hives, and immune-deficiency demand run much steadier year-round, so building content and campaigns around those conditions keeps your schedule fuller during the months seasonal allergy searches go quiet.
Because a lot of allergy and immunology revenue comes from an ongoing course of immunotherapy rather than a single visit, the value of a new patient isn't just the first appointment. It's the testing visit plus months or years of shot or drop visits that follow, as long as the patient stays on schedule. That's a very different number than a one-time procedure, and it's worth describing to any agency you're evaluating in exactly those terms.
Forget cost per lead as the number to chase here. Ask instead what it actually costs to book one new patient, and how that figure shifts once you account for how many of them finish their full immunotherapy course. Answering that honestly takes call, form, and booking tracking running from day one, or you're stuck guessing at which campaigns earned their spend.
Red flags, and the ownership questions that protect your clinic
Pay the closest attention to an agency whose reporting stops at website visits or call volume, with nothing more specific behind it. That tells you nothing about whether those calls turned into booked patients, let alone patients who stayed on their treatment schedule. Ask to see booking numbers, not just traffic.
A guaranteed number of new patients or a specific ranking is not something any honest agency will put in writing in a specialty this competitive, so treat that promise as a warning sign rather than a selling point. Also watch for handling of patient data that doesn't clearly account for privacy rules like HIPAA in the US, or PIPEDA and provincial rules such as Ontario's PHIPA in Canada. If an agency can't describe how patient information moves through their forms and tracking, that's a real gap, not a small one.
Your practice should hold the login to everything: the website, the ad accounts, the Google Business Profile, and the patient records generated through your forms and tracking. Before signing on, ask exactly what happens to your site, your ad accounts, and that patient data if the relationship ends, and expect a clear, specific answer, not a vague assurance.
Six questions to bring to your next call
One: 'How would you convince someone managing symptoms with over-the-counter medication to book a testing visit instead?' Two: 'How do you separate seasonal allergy marketing from food allergy, asthma, and immune-deficiency marketing?' Three: 'What's your plan for keeping immunotherapy patients on schedule once treatment starts?' Four: 'What's your real cost to book one new patient, not your cost per lead?' Five: 'Do the website, the ad accounts, and the patient data all sit under my practice's own name?' Six: 'How do you handle patient data given HIPAA, PIPEDA, and provincial privacy rules?'
The specificity of the answers matters more than how confident they sound. A specialist in this niche should be able to talk about testing versus guessing, immunotherapy adherence, and the seasonal split without you having to explain any of it first.
SearchPod runs this kind of system for allergy and immunology clinics: a clear clinical site with online scheduling, Google Ads split by condition, local SEO for the map pack, AI search visibility, and reminder email that helps keep immunotherapy patients on schedule. Every price is posted rather than negotiated case by case: Google Ads management runs 10% of monthly ad spend with a $600 minimum and zero markup on the media itself, SEO costs $50 per page with a 10-page floor each month, and a new website is priced as one of eight one-time packages, anywhere from $1,500 to upward of $20,000 depending on scope. There's no charge to get started, billing renews monthly with no long-term contract, and a 30-day guarantee protects you if that first month doesn't deliver. Fill out the form at /get-proposal; you'll hear back inside one business day. Whatever you decide, make every candidate answer these six questions before your practice signs anything.
