Your own site as the canonical source of truth

Why a clinic's own website has to carry the definitive version of every fact about it, and what happens when it does not.

Short answer

Every fact a system might state about your clinic should exist on your own site, in plain text, in one place, stated once. Where your site is silent, systems fall back on directories, aggregators and old records, which are frequently wrong. Being the clearest published source about yourself is the only durable way to influence how you are described.

There is a simple asymmetry at the heart of clinic discovery. Systems will describe your clinic whether or not you have given them anything to work with. If your site states the facts plainly, those statements are available. If it does not, the description gets assembled from directories, from aggregator databases seeded years ago, from review platform profiles and from whatever else exists.

You cannot prevent that assembly. You can determine what the best available source says.

The facts a clinic must publish about itself

  • The exact legal and trading name, and the relationship between them if they differ.
  • Every address, in full, with the postcode, on the page for that site.
  • Every phone number, and which site each belongs to.
  • Opening hours, including exceptions.
  • The services genuinely provided, named the way patients name them.
  • Who the practitioners are, their registrations and their registration numbers where publication is appropriate.
  • Regulatory registration where it applies, with the registration number.
  • Whether new patients are accepted, and whether a referral is needed.
  • How to complain, and the timescales involved.
  • Pricing, or the basis on which price is determined.

Most clinic sites carry perhaps half of this. The missing half is where incorrect descriptions come from.

State each fact once, in one place

A fact repeated in five places will eventually differ in five places. Opening hours in the footer, on the contact page, on the location page, in the markup and in the Business Profile will drift the first time they change and someone updates four of the five. Decide which page owns each fact, put the definitive statement there, and reference it elsewhere rather than restating it.

The drift test

Search your own site for your phone number and count the distinct formats. Then check your opening hours against the Business Profile and the structured data. On most clinic sites this takes ten minutes and finds at least one disagreement. Every disagreement is a fact a system has to choose between.

Your own website

HIGH CONTROL
What controls it
  • Every byte a crawler receives, and the speed it arrives at
  • The entity claims: name, address, identifiers, sameAs, service list
  • Canonical URLs, hreflang if used, and the internal link graph
  • Whether the page answers the question it was built to answer
What does not
  • How the answer is displayed once it leaves your server
  • Whether a third party republishes an outdated version of your facts
How to test it
  • Crawl the whole site and compare the URL list against the sitemap
  • Validate every JSON-LD block against the Rich Results Test
  • Measure field data, not only lab scores, for Core Web Vitals

What silence produces

When a page does not answer a question, the answer comes from elsewhere. Ask an assistant what a clinic charges for a treatment when that clinic publishes no pricing, and the response will be built from other sources: aggregators, forum discussion, competitors. It will frequently be wrong, and the clinic has no basis to object because it published nothing.

The same applies to whether you offer a treatment, whether you have parking, whether a referral is required and who works there. Silence is not neutral. It delegates the answer.

Clarity beats completeness

A fact buried in a paragraph of marketing prose is close to unusable. The same fact under a heading that asks the question, in a short self-contained sentence, is available to a reader in three seconds and to a retrieval system as a single passage. Where a fact matters, give it a heading and a paragraph of its own.

Making facts verifiable

Facts that can be checked against an independent record carry more weight than assertions. Link a regulatory registration to the register entry. Link a practitioner's registration to the public register. Where a professional body publishes a member list, link the entry. This is provenance, and it is available to clinics at no cost because the records already exist.

It also protects you. A clinic whose published credentials match public registers exactly is in a strong position if anything about its claims is ever questioned, which is a benefit that has nothing to do with search.

Third-party pages will still exist

Your site being canonical does not remove directory entries, review profiles or aggregator records. It means those records should agree with yours, and where they cannot be corrected, that yours is the clearer and more complete source. The connection between them is declared with sameAs, which is covered in detail elsewhere on this site.

Updating the source of truth first

Introduce one operating rule: when something changes, the website changes first, then the Business Profile, then the listings, then the markup, all within the same working day. The order matters because the site is the record everything else should be reconciled against, and because a change made everywhere except the site produces exactly the inconsistency you are trying to remove.

A twice-yearly source audit

  1. List the twenty facts a patient or a system might want about the clinic.
  2. For each, find where it is stated on the site. If it is not, that is the gap.
  3. Where it is stated more than once, decide which page owns it and simplify the others.
  4. Check the structured data agrees with the visible statement.
  5. Check the Business Profile and the three most visible directory listings agree.
  6. Ask an assistant to describe the clinic and note every incorrect fact, then find its source.

That audit takes an afternoon twice a year. It is the highest-yield exercise available to a clinic that wants to be described correctly, and it requires no supplier, no tool and no permission.

The pages most clinics are missing

Four pages come up repeatedly as gaps, and each of them answers a question that otherwise gets answered by somebody else.

  • A pricing page, even if it states ranges and the factors that move them. Silence here is filled by forums and aggregators.
  • A complaints page stating how to raise a concern, who receives it and the timescale for a response. Patients look for this before booking more often than clinics expect.
  • An aftercare page per treatment family, stating what is normal, what is not, and when to make contact. It reduces calls and it is quotable.
  • A regulation page stating what the clinic is registered for, with the registration number and a link to the public record.

Assigning ownership of facts

The practical mechanism that makes all of this survive contact with a real clinic is a table. One column for the fact, one for the page that owns it, one for the person responsible, one for the date last verified. Twenty rows covers a single-site clinic. It takes an hour to build and it converts a recurring cleanup into an ordinary maintenance task with a named owner, which is the only version that lasts beyond the enthusiasm of whoever started it.

No commercial links on this page

This article contains no affiliate links, no sponsored placements and no links to any agency, supplier, clinic or commercial brand. Nobody paid for it, nobody previewed it and no directory advertiser had sight of it. This publication does not rank or recommend agencies anywhere on the site.

Nothing here is medical or legal advice. Regulatory material summarises published guidance. Read the source before relying on it. Our full position is in the editorial standards.

Primary documentation and regulators only. We do not cite opinion surveys as though they were measurements of a system.

Frequently asked questions

Should we publish prices even if they vary?

Publish what you can state truthfully: a starting price, a range, or the factors that determine the price. Publishing nothing means the answer to a pricing question comes from somewhere you do not control.

Is it risky to publish practitioner registration numbers?

They are already public on the relevant register. Publishing them, and linking to the register entry, makes your claims verifiable. Follow the guidance of the relevant regulator on how credentials are presented.

What if a directory has wrong information we cannot change?

Submit a correction through whatever route exists, and make sure your own site is unambiguous. Where several sources disagree, the clearest and most complete one is the most likely to be relied on.

How does this differ from ordinary SEO content work?

Ordinary content work targets queries. This targets description: making sure that when a system states something about your clinic, the statement is yours and it is correct. The two overlap and are not the same job.

Which page should own the opening hours?

The location page for that site. Everything else, including the footer and the markup, should be generated from or checked against that single statement.
