Google Ads buys visibility today and stops when the budget stops. SEO takes months and then compounds on an asset you own. The right split depends on how competitive your local field is: in our study of 213 Canadian clinics, the median practice in Toronto covered 97 keywords while the median in Mississauga covered 28.
They are not alternatives, they are different instruments
Framing this as a choice is the reason most practices get it wrong. One buys attention now at a fixed price per click. The other builds an asset slowly that then produces attention at no marginal cost. They fail in opposite ways and they suit opposite situations.
Ads are rentable and immediate. Turn them on and inquiries arrive within days; turn them off and they stop the same afternoon. Nothing accumulates. A practice that has run ads for five years has exactly the visibility it is paying for this month.
Organic is owned and delayed. Nothing happens for months, then results build and keep building without further spend. A practice that published treatment pages three years ago is still collecting from them.
What does dental SEO cost compared with Google Ads?
The comparison only becomes concrete with real numbers on both sides.
On the paid side, a “dentist near me” click in Canada runs about $4.00; “invisalign” about $1.50; “emergency dentist” about $2.50. At a realistic 5–10% landing page conversion and a typical booking rate, a booked appointment lands somewhere between $50 and $160. That cost repeats for every patient, permanently.
On the organic side the cost is content rather than clicks. Across our 213-clinic study the median practice drew about 345 monthly organic visits with a traffic value of roughly $643 a month — that is what the same traffic would cost to buy. The top quarter drew over 666 visits. The eleven clinics covering more than 400 keywords averaged 3,433 monthly visits.
Put differently: the organic traffic the median Canadian clinic already receives would cost about $7,700 a year to replace with ads.
Your local field decides the weighting
This is the part most comparisons omit, and it changes the answer more than anything else.
We measured the two markets side by side. In Toronto the median clinic covers 97 keywords and draws 490 monthly visits, and only 19% of clinics cover fewer than 40 keywords. In Mississauga the median covers 28 keywords and draws 240 visits, and 60% cover fewer than 40.
A practice in Mississauga is entering a weak field where a modest amount of content clears the bar, so organic pays back sooner and ads are a bridge rather than a foundation. A practice in Toronto is entering a developed field where the median competitor already has real coverage — organic will take longer, which strengthens the case for running ads throughout rather than sequentially.
The same question, two different correct answers, decided by data you can look up in an afternoon.
When should a dental clinic start with Google Ads?
There are situations where paid search is clearly the right first purchase, and they have a common shape: you need chairs filled before organic could possibly arrive.
- A new practice or new location with no search history at all
- A competitive market where the median competitor already covers 90+ keywords
- An underused treatment with capacity you want filled this quarter
- A seasonal gap you can predict
- Testing whether a treatment has local demand before writing pages about it
When should a dental clinic start with SEO?
And the mirror image. These are situations where ad spend papers over a problem that content would solve permanently.
- A weak local field, where the median clinic covers under 40 keywords
- A practice already spending on ads with no idea what a booked appointment costs
- A site with four or five pages — the coverage problem is the whole problem
- A long-established practice with reviews and reputation but no treatment pages
- Any practice that wants acquisition cost to fall rather than stay flat
The rule that applies to both
Neither should start before you can tell where a patient came from. Dental inquiries arrive by phone far more than by form, so without call tracking most of the evidence is invisible.
This is not a preference about tooling. It is that the two channels are only comparable if measured the same way, and the comparison is the entire point of this article. A practice that cannot attribute calls will keep both channels running indefinitely, unable to tell which is carrying the result.
The second thing both share: a landing experience that converts. Traffic from either source arriving on a page with no visible phone number and a five-step booking form wastes the same amount of money.
A reasonable default for most practices
If you want one answer rather than a framework: run ads for the treatments with immediate capacity while building treatment pages every month, and expect the ratio to shift over eighteen months as coverage grows.
Review it quarterly against one number — cost per booked appointment by channel. When the organic figure falls decisively below the paid one, move budget. Until then, both are earning their place. The comparison is only meaningful once dental SEO has had time to produce something to compare.
Paid and organic compared on the terms that matter to a dental practice
| Google Ads | SEO | |
|---|---|---|
| Time to first inquiry | Days | Three to six months |
| Cost behaviour | Per click, permanently | Front-loaded, then near zero |
| Stops when you stop paying | Yes, same day | No |
| Typical Canadian cost | $4.00 per “dentist near me” click | Median clinic traffic worth $643/month |
| Best when | New location, competitive field, capacity to fill now | Weak local field, established practice, thin site |
| Main failure mode | Optimising for cheap clicks | Publishing thin pages that never rank |
FAQ
Neither in the abstract. Ads suit immediate capacity and competitive markets; SEO suits weaker local fields and practices wanting acquisition cost to fall over time. Most practices run both and shift the weighting as organic coverage builds.
Many practices reduce rather than stop. Compare cost per booked appointment by channel each quarter and move budget when the organic figure is decisively lower. Keep ads for treatments with capacity you need filled predictably.
Early movement typically appears in three to six months and compounds from six to twelve, with substantial variation by local market. A weaker field pays back sooner. Nobody can commit to a date.
Usually more effective rather than cheaper, because they cover different moments in the patient decision. What is genuinely wasteful is running both without call tracking, since you cannot then tell which produced the patient.
If you need patients this quarter, ads. If your site has four or five pages and your local field is weak, SEO, because ads on a site with no coverage rent visibility you could own.
