A practice writes "Otorhinolaryngology". A patient types "ear doctor near me". Both are describing the same service. Only one of them is a search anybody performs.
This gap is the single largest reason competent Nigerian practices are invisible online, and closing it does not require a budget.
Three kinds of search, three kinds of page
Patients arrive through roughly three patterns, and each needs different content.
Symptom searches. "Why does my chest hurt when I breathe". "Baby not gaining weight". These are people who do not yet know what service they need. They are answered by explanatory content, not by a services page, and they are the searches most practices ignore entirely.
Service plus place searches. "Dental clinic Yaba". "Ultrasound Ikeja". "Paediatrician in Surulere". These are people ready to act. They are answered by a page that clearly covers that service and that area, plus a well-maintained Google listing.
Named searches. Your practice name, or a doctor's name. These are people who already heard about you and are checking you exist. They are answered by your homepage and your Google listing, and they are the easiest to win.
Write the words patients use
You do not have to abandon clinical accuracy. You have to include both. A page titled "Ear, Nose and Throat (ENT) Clinic" that opens by saying what an ENT specialist treats, in ordinary language, serves the patient searching for "ear doctor" and the one searching for "ENT specialist Lagos" equally.
The practical exercise: sit with whoever answers your phone and write down, verbatim, the words patients use when they describe why they are calling. That list is your keyword research, and it is more accurate than any tool.
Local intent is almost always present
Even when a patient does not type a place name, the search engine assumes one. Somebody in Ikeja searching "dermatologist" is shown dermatologists in Ikeja. This means your area matters as much as your service, and it needs to be present in your content naturally: the neighbourhoods you serve, the landmarks near you, the areas patients travel from.
Mobile, and often mid-problem
Most of these searches happen on a phone, frequently at an inconvenient hour, sometimes by a relative rather than the patient. That has consequences for what a landing page should do: answer the question quickly, make the address and hours immediately visible, and make contact possible in one action.
Where to start
Take your three most profitable services. For each, write down the patient phrasing, the clinical phrasing, and the areas you draw from. Then check whether you have a page that genuinely covers that service, in those words, mentioning those places. Most practices discover they have one page covering everything, which competes for nothing.
That single audit usually produces a term list worth several months of work. Our SEO service begins with exactly this, because there is no point optimising pages that were never aimed at a real search.
