Picture a patient who types "colonoscopy near me" and taps your ad. What loads is the practice homepage. The homepage has a carousel about your new cardiology wing, a photo of the whole staff at the holiday party and a menu with nine specialties in it. Somewhere under the third scroll is a link to gastroenterology.
The patient was ready to book a colonoscopy. The page asked them to go find it. Google saw the whole thing, and it grades your ads partly on exactly that: whether the page a searcher lands on answers the search they typed. A homepage built to serve every specialty answers none of them well, and you pay for that in the auction.
Google's Auction Weighs Six Things, and Your Bid Is Only One of Them
Most practice owners picture the Google Ads auction as a price war: the highest bid gets the top spot. Google's own description of Ad Rank lists six things it weighs every time an ad competes:
- Your bid, the ceiling on what you'll pay per click, though you often pay less.
- Ad and landing page quality: Google asks whether the ad earns the tap and whether the page keeps the ad's promise, including how simply a visitor can find their way around.
- Ad Rank thresholds, the minimum quality an ad needs to show at all.
- How competitive the auction is, which decides how close two advertisers' ranks are and what the winner pays.
- The searcher's context, including their location, the device they're on and the time of the search.
- The expected impact of your assets, like a phone number or extra links under the ad.
The bid is one slice of six. The ad and the page make up another, and they're the slice a practice controls most directly.
Quality Score Grades Your Account. The Auction Never Reads It.
Inside every account, Google shows a Quality Score from 1 to 10 for each keyword. Google builds it from a click forecast, a relevance check between ad and search, and a verdict on the landing page. Owners fixate on that number, yet Google says plainly that the auction never uses it. The score is a diagnostic, a report card comparing your ads and pages with other advertisers' for the same keyword.
The auction runs its own quality check on every search, and Google spells out the reward: better ads tend to earn cheaper clicks. The work that lifts the report card usually lowers the price too. Each of the three parts has its own lever, and the rest of this chapter pulls them one at a time.
Expected Clickthrough Rate Ignores Your Ad's Position. Better Copy Moves It, Bigger Bids Don't.
Google's click forecast, officially expected clickthrough rate, predicts whether your ad earns a tap for a given keyword. The part people miss is that Google adjusts for position. Placement and assets are factored out of the prediction, so it rates the ad's own pull rather than the real estate you paid for.
That separates two things practices often blur. The top spots do win more clicks, and a higher bid can buy you a higher spot. But a higher bid can't make an unconvincing ad more clickable. If expected clickthrough rate reads "Below average," the fix is the words: a headline that repeats the service the patient searched for, and copy that sounds like how patients describe you. Chapter 8 builds that copy from real patient reviews.
Ad Relevance Is the Cheapest Lever: One Tight Ad Group per Service
Ad relevance asks a simple question: does this ad match this search? It's the easiest of the three to fix, because it's decided by how you build the account, not by how much you spend.
Keep every ad group small: a single theme, roughly five or six keywords a patient would treat as the same request, and one ad written for that request. Here's what that looks like for gastroenterology, using searches from our example market, San Diego:
- Ad group: colonoscopy. Searches like "colonoscopy" (3,600 a month) and "colonoscopy screening" (170). The ad says colonoscopy in the headline and points to the colonoscopy page.
- Ad group: GI doctor. Searches like "gastroenterology near me" (590) and "gi doctor san diego" (70). The ad names the gastroenterologists and points to the GI page.
Put all of those in one group under one generic ad about "digestive health," and every search gets an ad that half fits it. Split them, and each search meets an ad that repeats its own words. Multiply that across a multi-specialty practice and the difference is dozens of small, sharp ad groups instead of one big blurry one. Chapter 5 builds the keyword lists, and Chapter 14 lays out how the service lines sit side by side in one account.
A Homepage Can't Win the Auction for Six Specialties at Once
The third part is landing page experience. Each tight ad group needs a page to match: the colonoscopy page for colonoscopy searches, the GI page for GI searches. A multi-specialty homepage that lists primary care, cardiology, GI, allergy, pain and physical therapy is partly relevant to everything and fully relevant to nothing. The page should say plainly, in this order, who you treat, which conditions and procedures, which insurance you take, and how to book.
Then there's speed. We ran Google's PageSpeed Insights mobile test on the homepages of the 14 practices we profiled in our example market, each one a verified Google Search advertiser. It's a lab test, one run per page, and your own results will vary from run to run. Seven of the 14 took longer than 10 seconds to draw their main content on a phone, and ten of the 14 scored under 70 out of 100.
Google's help center says "Faster landing pages typically lead to more conversions" and that landing page experience "is an important factor in your Quality Score." In a retail example on another page, Google reports that a 1-second delay on mobile can cut mobile conversions "by up to 20 percent." That's retail, not medicine, and we'd expect the same direction for a patient staring at a blank screen. Run PageSpeed Insights, free at pagespeed.web.dev, on every landing page, not just the homepage, and look at the first screen on a real phone before you raise a single bid.
Our specialty guides go deeper on the page each field needs. The dermatology guide covers why one medical dermatology page can't win for acne, eczema and moles. The plastic surgery guide covers how Google judges a procedure page before you pay for the click. The med spa guide covers why Google grades the treatment page, not the booking widget.
Yelp Showed Up on 14 of the 25 Health Searches We Checked. The Ad Is Often Your Only Way Onto Page One.
One more reason the landing page carries so much weight in healthcare. We pulled 25 healthcare searches in our example market and looked at the free results under the ads. Yelp appeared on 14 of them. One health system appeared on 8, Healthgrades on 8, Reddit on 8, U.S. News on 7 and Zocdoc on 5.
Directories, review sites and big health systems take up much of the free space. For an independent practice, the ad is often the only way onto that first page, so the landing page isn't one stop on the patient's visit. It is the visit.
Next: Build the Keyword Lists From Your Competitors' Websites
With a page for every ad group, the next job is filling the groups. Chapter 5 starts Keyword Planner from competing practices' websites, groups what comes back and weeds out what doesn't belong.
Catch up on Chapter 1 on tracking bookings without leaking symptoms, Chapter 2 on buying the ready patient first and Chapter 3 on pricing each specialty, or see every chapter on the guide home for Google Ads for Healthcare. When a practice hires us for Google Ads management, every ad group gets its own landing page before the first campaign goes live.
