Why Your Clinic's Google Ads Cost More Than a Competitor's for the Same Click
We get some version of this question from almost every clinic we onboard: "why is our cost per click higher than it was last year, when we haven't changed anything?" Usually the honest answer is that a competitor cleaned up their account structure, and the auction rewarded them for it. 💖 Google Ads isn't just an auction on bid amount — it's an auction on relevance, and most clinic accounts we review are set up in a way that actively punishes them on that score.
What most clinics get wrong
The most common setup we see is one broad ad group called something like "Physio Services" containing keywords for back pain, sports injuries, post-surgical rehab and general check-ups, all pointing at the same generic homepage. Google can tell when an ad and landing page are trying to be relevant to everything at once, and it prices accordingly — a close match between what someone searched, what the ad says, and what they land on on consistently earns a lower cost per click than a generic "book now" catch-all, even with an identical bid.
The practical restructure (do this in order):
- Split one broad ad group into service-specific ad groups. Instead of "Physio Services," create separate groups for each distinct service you actually run as its own page — e.g. sports injury, back and neck, post-surgical rehab.
- Write two to three ads per ad group using the exact service name from the group, so the headline mirrors the search term as closely as possible.
- Point each ad group at its matching service page, not the homepage — if that page doesn't exist yet, build a simple one before running the ads, not after.
- Add the service name and location to at least one headline in each ad, since local and service-specific intent both lift relevance.
- Use sitelink extensions pointing to your FAQ, booking page and other services, which gives Google more signals that your ad is a genuinely useful match for the search.
- Review Quality Score components monthly (expected click-through rate, ad relevance, landing page experience) in the keyword details view, and fix whichever one is flagged "below average" first.
How to actually set this up
Start with your search terms report, not your ad groups — it'll show you the actual phrases people are typing, which is the clearest guide to how granular your ad groups should be. Group search terms that share clear intent (same service, similar wording) into their own ad group, then write ad copy using that group's specific language. Keep ad copy generic and service-based — describe what the service is and who it's for, not a promised result. Please note: general information, not legal advice — check current official guidance before relying on it when writing ad copy that references health services, and keep any examples of claims about outcomes out of your ads altogether. A landing page that matches the ad group's specific service, with a clear single call to action, is just as important as the ad copy itself — Google measures landing page relevance, not just click-through rate.
Mistakes to avoid
- Running every service through one generic ad group. This is the single biggest driver of inflated cost per click in clinic accounts.
- Sending every click to the homepage. A homepage trying to represent every service dilutes landing page relevance for all of them.
- Writing ad copy that promises outcomes. Beyond the compliance risk, outcome-based claims rarely match what a specific landing page actually delivers, which hurts relevance anyway — keep copy service-based and general.
- Ignoring the search terms report. It's the fastest way to see where your ad groups are too broad or targeting the wrong intent entirely.
- Increasing bids to fix a relevance problem. A higher bid can buy a better position temporarily, but it doesn't fix the underlying cost-per-click gap — only a better ad-to-landing-page match does that sustainably.
Frequently asked questions
How long does it take to see cost per click improve after restructuring ad groups?
Usually a few weeks of consistent data before Google's auction fully reflects the new structure, though some improvement can show earlier. It's not instant, and a newly split ad group sometimes looks worse for the first week or two before it settles.
Does a higher Quality Score always mean a lower cost per click?
Generally yes, but not in every single auction — competitor bids, time of day and search intent all move the final price too. Quality Score is a strong lever, not the only variable, so don't expect it to fully explain every fluctuation you see.
Do we need a separate landing page for every single keyword?
No — per ad group, not per keyword, is the right level of granularity for most clinics. A dedicated page per distinct service is realistic; a dedicated page per keyword variation usually isn't worth the maintenance for a clinic-sized team.
Is it worth paying an agency just to fix ad group structure?
If your account has one or two broad ad groups covering everything, this is genuinely a few hours of focused work a clinic owner or office manager can do themselves following the structure above — it doesn't require ongoing agency management, just the initial restructure.
