The surface register

Every discovery surface a UK clinic appears on, with what controls it, what does not and how to test it. The reference this publication is built on.

A discovery surface is any place a patient can encounter a clinic before they contact it. Each one is governed by a different system, and the first step in improving any of them is knowing which parts are yours. Every panel below names a surface, what controls it, what does not, and how to test the current state.

SURFACE 01

Organic web results

PARTIAL CONTROL
What controls it
  • The HTML a crawler receives, including the rendered DOM
  • Titles, headings, body copy, internal links and canonical tags
  • Structured data that describes what the page is about
  • Whether the page is fast enough to be usable when it arrives
What does not
  • Which query the page is shown against
  • Whether a result gets a rich result treatment on any given day
  • The other nine results and the features that push them down the page
  • How often the index is refreshed for a given URL
How to test it
  • Search Console URL Inspection on the live URL, not the cached one
  • site: and inurl: probes to confirm the page is indexed at all
  • A fetch with JavaScript disabled to see what exists before render
  • The Performance report filtered to that page, by query, over 28 days
SURFACE 02

The local pack

PARTIAL CONTROL
What controls it
  • The accuracy and completeness of the Business Profile behind the listing
  • Primary and secondary categories, and the services attached to them
  • Whether the address, name and phone number match everywhere else
  • The volume, recency and subject matter of reviews the profile attracts
What does not
  • The distance between the searcher and the clinic
  • Whether a pack appears for the query at all
  • How many results the pack shows on a given device
  • Which competitors are eligible in the same radius
How to test it
  • Search the query from a device with location set to the target area
  • Compare the profile's categories against the ones competitors use
  • Check the profile in the Business Profile manager for pending edits
  • Track pack presence per query rather than a single average position
SURFACE 03

Google Maps

PARTIAL CONTROL
What controls it
  • Pin placement, service area, opening hours and attributes
  • Photos uploaded by the business and the products or services listed
  • The categories that decide which Maps searches the pin is eligible for
What does not
  • User-submitted photos, questions and suggested edits
  • Whether Google accepts a suggested correction from a member of the public
  • The ranking of the pin against a moving map viewport
How to test it
  • Open Maps, move the viewport, and record where the pin appears and drops out
  • Review the Q and A tab weekly for unanswered public questions
  • Audit suggested edits in the Business Profile manager
SURFACE 04

Google Business Profile

HIGH CONTROL
What controls it
  • Name, address, phone, website URL and appointment link
  • Primary category, additional categories and the services list
  • Opening hours, special hours, attributes and the business description
  • Photos, posts, products and the questions the business answers itself
What does not
  • Whether the profile is shown for a query
  • Public edits, review content and the star average they produce
  • Whether an appeal against a suspension succeeds
How to test it
  • Read the profile back as a member of the public, not as the owner
  • Check every field against the guidelines for representing a business
  • Confirm the website URL resolves without a redirect chain
SURFACE 05

AI answers and assistants

LOW CONTROL
What controls it
  • Whether your content is crawlable by the relevant user agents
  • How clearly a page states the fact you want quoted, and where
  • Whether the same fact is consistent across your site, profile and listings
  • Structured data that removes ambiguity about who and what you are
What does not
  • Whether a model chooses to cite you
  • Which passage it lifts, or how it paraphrases it
  • Whether an answer appears at all for a given prompt
  • The training data of any model already released
How to test it
  • Run the same prompt repeatedly and record what is cited, with dates
  • Check server logs for AI user agents rather than guessing at access
  • Verify the fact you want quoted appears verbatim on a crawlable page
SURFACE 06

Review platforms

PARTIAL CONTROL
What controls it
  • Whether you ask, when you ask and how easy you make it
  • Whether every review gets a reply, and how fast
  • The accuracy of the profile the reviews are attached to
What does not
  • What a patient writes, or the score they leave
  • Whether a platform removes a review you report
  • Which review platform a searcher happens to trust
How to test it
  • Track review count and mean rating by month, not as a single lifetime figure
  • Record response rate and median response time
  • Read the last twenty reviews for the words patients actually use
SURFACE 07

Directories and citations

HIGH CONTROL
What controls it
  • The name, address and phone number you submit, character for character
  • Which directories you claim and which you deliberately ignore
  • The website URL and category on every claimed listing
What does not
  • Whether an aggregator republishes stale data it scraped years ago
  • Whether a directory ranks for your brand name
  • The design and quality of the directory itself
How to test it
  • Search the exact phone number in quotes and read every result
  • Search the brand name plus the town and audit the first three pages
  • Keep one canonical NAP string in a document and diff every listing against it
SURFACE 08

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

Briefings when a surface changes

We write when documented platform behaviour changes, which is roughly monthly.
