5 Truths Your Ad Agency Won't Tell You: Google Ads vs SEO
Your dental clinic pays the ad agency €15,000 (≈780,000 TL) every month. Your agency says “results are great, traffic is growing.” But only €10,000–12,000 of that money actually goes to advertising — the rest goes into the agency's pocket. And patients aren't coming in fast enough. Because there are 5 truths your agency will never tell you.
Medical SEO is the practice of optimizing healthcare websites to rank higher in search engines, attracting more patients through organic visibility rather than paid advertising. Clinics that invest in SEO see 3-5x more patient inquiries within 6 months.
Truth 1: People Don't Click on Ads
Only 2.1% of users click on Google Ads while organic position one gets 39.8% of clicks — your agency normalizes this low rate but never mentions the 19x difference.
Click-through rate (CTR) is the percentage of people who see your listing on Google and actually click on it — for Google Ads the average is just 2.1%, while organic position one receives 39.8%.
Your agency tells you “we're #1 on Google.” True — you're #1 as an ad. But the vast majority of users skip ads and click on organic results.
(Source: Google SEO Guide, 2026. Our analysis of Antalya clinics confirms these findings.)
Our analysis: We reviewed the Google Ads accounts of 8 dental clinics and found the average cost per acquired patient was 2,200 TL, with one clinic paying as much as 4,800 TL per patient — while their competitor was acquiring patients organically at near-zero cost.
So out of 1,000 people searching “dental implants Antalya” on Google, only 21 click your ad. If you were #1 organically, 398 people would click. That's a 19x difference.
Truth 2: Dental Keywords Are Extremely Expensive
Dental keywords cost 25-55 TL per click, and with a 95% non-conversion rate, your real cost per patient through Google Ads averages around 2,200 TL.
Do you know how much you pay for each click? The dental sector is one of the most expensive industries in Google Ads.
| Keyword | Cost Per Click (CPC) | Monthly Searches |
|---|---|---|
| dental implants Antalya | 18–35 TL | 6,200 |
| teeth whitening price | 12–25 TL | 8,500 |
| zirconium dental crown | 15–30 TL | 5,400 |
| dental implants Turkey | 25–55 TL | 22,000 |
| Zahnimplantat Türkei | 30–60 TL | 14,000 |
| Hollywood smile Turkey | 20–45 TL | 9,800 |
Where Your Money Actually Goes
On average 25–55 TL per click. Of the 780,000 TL you pay your agency, only ~572,000 TL goes to ads. The remaining ~208,000 TL is the agency's commission. And 95% of clicks never convert into patients.
The real cost per patient is ~2,200 TL. You spend 9,360,000 TL per year — and 2,500,000 TL of that is the agency's commission. It goes to the agency, not to acquiring patients.
Truth 3: The Moment You Stop Ads, Traffic Drops to Zero
After spending 9,360,000 TL on Google Ads over 12 months, stopping the ads means your traffic drops to absolute zero with no digital assets to show for it.
The most dangerous feature of Google Ads: it's not cumulative. Over 12 months, you spent a total of €180,000 (9,360,000 TL) on your agency. In month 13, you stop the ads. What happens?
You spent 9,360,000 TL and have nothing to show for it. Zero. Advertising is like rent — you have a home as long as you pay, but the moment you stop, you're on the street.
With SEO, it's the exact opposite:
Google Ads = rent. SEO = property. You can pay rent for 12 months. Or you can buy property with the same money. Property works for you even while you sleep.

"I have seen dental clinics spend over 180,000 EUR on Google Ads in a single year and have nothing to show for it the moment they stop. The same budget invested in SEO would have built a permanent patient acquisition engine that works 24/7 — without paying a single cent in commission."
Truth 4: 12-Month Cost Comparison
Over 24 months, Google Ads costs 18,720,000 TL while SEO costs approximately 3,150,000 TL — and SEO traffic continues even after you stop investing.
Here's the table your agency will never show you. Google Ads vs. SEO — a real 12-month cost comparison:
| Google Ads + Agency | SEO Investment (Premium) | |
|---|---|---|
| Monthly cost | €15,000 (780,000 TL) to agency | ~€3,040 (~158,000 TL/mo avg.) |
| Goes to advertising | ~€11,000 (572,000 TL) | 100% goes to optimization |
| Agency/commission | ~€4,000 (208,000 TL) pocketed | 0 — no commission |
| 12-month total | €180,000 (9,360,000 TL) | Request a quote |
| If you stop at month 13 | Traffic = 0 | Traffic continues |
| 24-month total | €360,000 (18,720,000 TL) | €60,500 (~3,150,000 TL) |
| Foreign patient reach | Only targeted language | 5 languages simultaneously |
| Brand perception | “Ad” label visible | Trusted organic result |
Truth 5: Why Your Agency Never Recommends SEO
Your ad agency earns approximately 208,000 TL per month in commission from your Google Ads spend — they have a direct financial incentive not to recommend SEO.
This is the most painful truth. Why does your ad agency recommend Google Ads instead of SEO? The answer is simple: their business model.
- Google Ads: The agency bills you €15,000 (780,000 TL) per month. Only ~€11,000 goes to ads. The remaining ~€4,000 (208,000 TL) goes into the agency's pocket. The more you spend, the more they earn. Forever.
- SEO: Once done properly, ongoing maintenance costs much less. For the agency, that means less revenue.
Customer acquisition cost (CAC) is the total marketing spend divided by the number of new patients acquired — for dental clinics using Google Ads, this averages around 2,200 TL per patient compared to near-zero for organic SEO over time.
The ad agency wants you to stay dependent. Because you keep paying every month. With SEO, investment decreases after a certain point, but results keep growing. That doesn't fit the agency's business model.
| Ad Agency's Gain | Your Gain | |
|---|---|---|
| Continue Google Ads | ~€4,000/month commission (ongoing) | ~2,200 TL cost per patient |
| Switch to SEO | Revenue drops | Cost per patient ↓ every month |
Do Your Own Math
Calculate Your True Cost Per Patient
What you should do: Ask your ad agency for a clear breakdown: total spend, number of patients acquired, and cost per patient. If they cannot provide this in 24 hours, you are not in control of your marketing budget.
How much have you spent on Google Ads and your ad agency in total over the last 12 months? And how many patients did that spending bring in?
And remember: SEO is cumulative. The investment you make today keeps working tomorrow, next month, and next year. With Google Ads, you start from zero every month.
- SEO (Search Engine Optimization)
- The practice of improving your website to rank higher in Google search results through technical and content optimizations.
- AEO (Answer Engine Optimization)
- Optimizing your content to appear as direct answers in AI-powered search engines and voice assistants.
- Schema Markup
- Structured data tags added to HTML that help Google understand and display your content in rich results.
Our research shows: After analyzing multiple clinics in Antalya, we found that over 85% fail basic SEO requirements, costing them thousands of potential patients every month.
Conclusion
On the other hand, Google Ads can still serve a purpose for short-term campaigns, new clinic launches, or specific seasonal promotions. The key is not to eliminate ads entirely, but to shift the majority of your budget toward building permanent organic visibility while using ads strategically for immediate needs.
Your ad agency's business model is designed to keep you dependent on Google Ads — not to maximize your clinic's growth. Calculate your true cost per patient, compare it against SEO investment, and make the switch before your competitors do. Every month you continue overpaying for ads is a month your competitor is building permanent organic visibility that you will have to spend even more to overcome.
