Nearly every physician we work with arrives with the same question: where should I put my advertising budget, Google or Facebook and Instagram? It's a fair question, but it's the wrong one. Google Ads and Meta Ads don't compete for the same patient or solve the same problem. One reaches the person already searching for a specialist who wants to book today; the other creates the desire to be treated in someone who didn't even know you existed. Understanding that difference is what separates a practice that burns money on clicks from one that fills its calendar predictably. In this guide we break down when each channel makes sense, how they work together, and what to watch for so your advertising stays compliant with COFEPRIS.
Google Ads: capturing the intent of patients already looking for you
Google Ads runs on search intent. When someone types "dermatologist in Guadalajara," "how much does a root canal cost," or "OB-GYN near me," they've already identified a problem and are actively hunting for a solution. That patient sits at the very bottom of the funnel: they don't need convincing that they need care, they need to choose who to see. That's why a patient who arrives from a search tends to book faster and with less friction. The trade-off is that you only show up against demand that already exists: if nobody searches for your procedure, there's no one to show the ad to. Google is your channel when you offer services people search for by name (specialty consults, urgent care, specific treatments) and when you compete in an area full of patients who have half made up their minds. Here your Google Business Profile and your reviews are what turn a click into a call or a WhatsApp message.
Meta Ads: generating demand where none exists yet
Meta Ads (Facebook and Instagram) works the other way around. Nobody opens Instagram looking for a plastic surgeon; they're scrolling through content and your ad interrupts them. What looks like a weakness is actually its superpower: Meta generates demand. With targeting by age, location, interests, and behavior, you can plant the seed in patients who didn't yet know they wanted treatment, show results, educate them about a procedure, and build your practice's brand. It's the ideal channel for aesthetic, wellness, orthodontic, and preventive services, or any elective, emotionally driven treatment where the patient needs to see, understand, and trust before taking the step. Short-form video and before-and-after stories perform well, but this is where the COFEPRIS line gets thin: don't promise results, don't use testimonials that guarantee a cure, and be careful with how you handle patient imagery. Meta fills the funnel at the top; Google closes it at the bottom.
Why most profitable practices run both
The reason so many physicians end up running both channels isn't spare budget, it's how patients actually behave. A real cycle looks like this: someone sees your Instagram video about a treatment (Meta generates the demand), thinks it over for a few days, then searches your name or your specialty on Google to confirm you're credible (Google captures the very intent you just created). If you only show up in one place, you lose half the equation. Meta without Google means sparking interest that cools off because, when the patient goes looking for you, they find your competitor instead. Google without Meta means fighting only over existing demand, which is more expensive and more contested, while never expanding your market. Together, every peso works harder: Meta lowers your cost per patient on Google by getting more people to search your brand, and Google converts the interest Meta stirred up. It's not about choosing, it's about giving each channel the job it does best.
How to decide where to start based on your practice
If your budget is tight and you need results soon, it almost always makes sense to start where intent already exists: Google. Begin by capturing the people searching for you, measure how many of those clicks turn into appointments over WhatsApp or the phone, and use that data to learn what a patient is truly worth. Once that channel is profitable and you know your cost per booking, open Meta to expand the market and feed the top of the funnel. The exception is elective services with little search volume, like aesthetics and certain wellness treatments, where demand has to be built and Meta should come first. Either way, the most common mistake isn't picking the wrong platform, it's failing to measure. Without tracking which ad produced each WhatsApp message, each appointment, and each patient who actually showed up, you're optimizing blind and neither platform will give you its best. Doctoralia, your Google profile, and your WhatsApp flows all need to be wired into that measurement from day one.
