Your practice is mentioned in more places than you maintain: directories you never signed up to, association pages, aggregator sites, an old listing from a previous premises, social profiles set up by a former staff member.

Search engines use those mentions to build confidence that your practice is a real, established business at a specific address. That works by matching your name, address and phone number across sources. Where they match, confidence rises. Where they differ, it does not.

What counts as a difference

More than you would expect. All of these are treated as potentially different businesses:

  • "REWA Medical Centre" against "REWA Medical Center" against "REWA Medical Ctr"
  • "No 12 Awolowo Road" against "12 Awolowo Rd" against "12, Awolowo Road"
  • A landline on one listing and a mobile on another
  • "Suite 4, Plot 8" present in one listing and absent from another
  • An old address that was never removed

Individually trivial. Collectively they mean that instead of one business with many confirmations, you look like several businesses with one confirmation each.

The Nigerian complication

Addressing here is genuinely inconsistent. Plot numbers, house numbers, suite numbers, estate names, and the near-universal use of landmarks all vary in how they are written. Some directories will have your address in a form nobody in your practice has ever used.

This makes the exercise more necessary, not less. You cannot control how others wrote it historically, but you can decide what the canonical version is from now on.

Do this once, properly

  1. Write down the canonical version. One exact string for the practice name, one for the address, one primary phone number. Put it in a document that staff can find.
  2. Search for yourself. Your practice name, your phone number, your address, each as a search. Note every place you appear.
  3. Correct what you control. Your own site, footer, structured data, Google listing, social profiles.
  4. Claim what you can. Many directory listings can be claimed and edited free.
  5. Request removal of the genuinely dead ones, particularly old addresses, which do active harm.

Then keep it

The canonical string goes into whatever you use to create new listings, so the problem does not rebuild itself. When you next change premises or numbers, the document tells you exactly what has to change and where.

This is unglamorous and it will not feel like marketing. It is, however, one of the few pieces of local SEO where the work is finite, the outcome is verifiable, and nobody has to guess.
