What is the difference between local SEO and Google Ads for a clinic?
Local SEO earns unpaid visibility in the map results and local pack, driven mainly by your Google Business Profile, reviews and local relevance. It takes months and continues working afterwards. Google Ads buys placement above those results instantly, for as long as you keep paying. Both compete for the same patient at the same moment; one is an asset you build and the other is a tap you turn on.
Dentistry and most clinical categories are unusually winnable locally, because the standard of local SEO among clinics is low. Most practices have a Business Profile created once at opening, a handful of old photographs, an approximate primary category and no review process at all. That is not a competitive market. It is an open one.
The reason to still run ads is timing. Local pack visibility takes months to build, and a clinic with empty chairs this quarter cannot wait for it. Ads solve the immediate problem while the durable asset is being built.
