A pediatric clinic emailed us in a mild panic a couple of months back. Their Google Ads spend had jumped almost 30 percent in two weeks, the clicks were up, but the phone was not ringing any more than usual. Nothing in their strategy had changed. What had changed was a setting they never touched: Google had switched on a new feature called AI Max, and their campaign was now bidding on all sorts of searches they never chose. Some were great. Many were people googling "baby fever at night" and "is a rash normal," reading the ad, and leaving. The budget was going somewhere. It was just not going to booked visits.

That is the double edge of AI Max in one story. So let us walk through what it is, what Google claims, where it helps a medical practice, and where it burns money if nobody is watching.

What AI Max for Search actually is

AI Max for Search is not a new campaign type. It is a setting, a toggle, that you switch on inside a Google Search campaign you already run. Google announced it at Google Marketing Live in May 2025 and rolled it out globally through the second half of the year, so if you run ads, it is probably already sitting in your account, on or waiting to be turned on. The clearest plain English rundown comes from Search Engine Land, and Google lays out its own pitch on the Google blog.

When you turn it on, AI Max changes three things about how your Search ads run:

In short, you hand three decisions that used to be yours, who to show the ad to, what it says, and where it sends people, over to Google's AI. That is the whole idea. And whether that is smart depends entirely on how tightly the rest of your account is set up.

What Google claims, and what is real

Google's headline number is that advertisers outside retail who switch on AI Max see about a 14 percent lift in conversions at a similar cost per conversion, and campaigns that leaned heavily on exact and phrase match keywords see up to a 27 percent lift, according to figures reported around its launch. Those are Google's own numbers, measured across large advertisers, so treat them as a ceiling, not a promise for your solo dermatology office.

Here is the honest read. The lift is real, but it comes from AI Max finding searches your keyword list was too narrow to catch. If your account was tightly built with a small keyword list, there is genuine upside in letting the AI fish in a wider pond. If your account was already loose, with broad keywords and weak negatives, AI Max just pours fuel on a fire that was already wasting money. The tool amplifies whatever discipline, or lack of it, already exists in your account.

14% average lift in conversions Google reports for non retail advertisers using AI Max, up to 27% for keyword heavy campaigns. Real gains, but measured on big accounts with tight tracking, not a guarantee for a small practice.

Why healthcare is a tricky place to hand the wheel to AI

Broad, AI driven matching is riskier in healthcare than in most industries, for one simple reason: medical searches are full of intent that looks commercial but is not. Someone typing "why does my knee hurt" is not ready to book an orthopedic consult. They want to read for two minutes and move on. A keyword list you built by hand naturally filters those out. AI Max, chasing "relevant" searches, may serve your ad to all of them.

That is exactly what bit the pediatric clinic. Their spend was landing on anxious late night symptom searches, which are emotionally powerful and commercially useless. The same trap catches practices in every vertical: a med spa paying for "does Botox hurt," a vein clinic paying for "leg pain causes," a therapy practice paying for "am I depressed quiz." All related. Almost none of them book. This is the same money leak we wrote about in why your ad clicks are not booking patients, and AI Max can make it bigger before you notice.

There is also a brand safety layer specific to medicine. You want control over which pages your ads point to and which searches you appear on, because in healthcare the wrong pairing is not just wasteful, it can be misleading. Letting AI pick your landing page means a person searching for one service can land on a page about another. That is a great way to lose a click you paid for.

The one thing that makes AI Max safe: the search terms report

Here is the good news, and the reason AI Max is far more manageable than its cousin Performance Max. It stays inside Search, and it keeps showing you the searches. The search terms report labels AI Max as its own match type, and a source column tells you whether each new search came from broad match expansion or keywordless technology. You can see exactly what the AI is spending your money on.

That transparency is the whole game. It means AI Max is not a black box you either trust or fear. It is a tool you supervise. The workflow that keeps it profitable is boring and it works:

AI Max or Performance Max?

Owners mix these two up constantly, so it is worth being clear. Performance Max is a separate campaign that scatters your budget across Google's entire network, Search, YouTube, Gmail, Display, Discover, and Maps, with very little visibility into where your ads run or which searches triggered them. AI Max is narrower and, frankly, friendlier. It lives inside a normal Search campaign, only touches Search, and keeps the search terms report intact.

For most medical practices, that makes AI Max the more sensible place to let AI help, because you keep the ability to see and steer. If you have wrestled with the opacity of Performance Max, we compared the trade offs in whether Performance Max is worth it for medical practices. The short version: AI Max gives you more of the upside of automation with more of your control intact.

So, should you turn it on?

Our honest answer, the same one we give clients: yes, but only with a hand on the wheel. AI Max is a good tool being handed to a lot of people who are not set up to supervise it, and that is where the damage happens. The gains Google advertises are real, and finding patient searches your keyword list missed is genuinely valuable. But the tool rewards accounts with tight negatives, clear conversion tracking, and someone reviewing the search terms report every week. It punishes accounts that are set and forgotten.

If your Google Ads are a side task nobody has time to babysit, flipping on AI Max is how you end up like that pediatric clinic: more spend, more clicks, the same empty schedule. If someone is watching it closely, it can widen your reach without widening your waste. The setting is not the strategy. The supervision is.

Where EtherealMinds fits

Most practices do not lose money on Google because the tools are bad. They lose it because nobody is home when Google flips a switch. New features arrive turned on, budgets drift, and by the time the schedule feels the difference, thousands are already gone. That is the gap we close.

Managing ads is part of our patient acquisition system: we decide where AI Max helps and where it hurts for your specific practice, build the negative keyword lists and brand controls that keep it honest, and tie every conversion to a real booked appointment so a "lift" actually means more patients, not more noise. It works alongside landing pages built to turn clicks into bookings and the organic search work that brings in patients you are not paying per click for, so you are not renting every visit forever. You get the reach of Google's AI with a person making sure it spends on the searches that fill your chairs.
