What we tested and how

aivisible.co.uk audits AI visibility for UK small businesses as part of our free audit service. Each audit involves testing the business across ChatGPT, Perplexity, and Google AI Overviews using the types of queries their customers would realistically ask. The results below reflect patterns across those audits.

Headline findings

~85% have zero AI visibility

The majority of UK SMEs tested do not appear in any AI-generated answer to realistic customer queries about their sector and location. They are effectively invisible to AI-driven discovery.

Schema markup is the clearest differentiator

The businesses that do appear in AI answers share one thing above all others: they have structured data on their website. Schema markup is the most reliable predictor of AI visibility in our audits.

Google ranking does not predict AI visibility

Several businesses audited rank on page one of Google for their target keywords but do not appear in ChatGPT or Perplexity answers. AI and traditional search visibility are related but distinct.

The five most common failures

1
No schema markup at all, found on the majority of SME websites audited. Without structured data, AI systems have no reliable machine-readable way to identify the business type, location, services, or credentials.
2
Wrong or generic business type in schema, some businesses have schema, but use generic types like LocalBusiness when a specific type (Plumber, Dentist, Restaurant) is available and significantly more effective.
3
Credentials not in structured data, Gas Safe, GDC, NICEIC, SRA, and other professional credentials are often mentioned on websites but not in schema markup. This means AI systems cannot reliably cite them as authority signals.
4
No answer-first content, websites written to convert human visitors do not answer the specific questions AI receives from customers. Businesses need content explicitly addressing the questions in their sector FAQ.
5
Inconsistent NAP across directories, conflicting name, address, or phone data across Google Business Profile, sector directories, and the website creates entity confusion that reduces AI citation confidence.

Which sectors are most affected

AI visibility issues affect all SME sectors, but some face a more acute problem because local discovery is central to how customers find them:

Trades & home services
Plumbers, electricians, builders — highest local intent queries, lowest schema adoption rates.
Independent hospitality
Restaurants, cafes, pubs — frequent AI recommendation queries, often no structured data or OTA inconsistency.
Professional services
Solicitors, accountants — high-value queries, but most firms lack any schema or FAQ content on cost and process.
Healthcare & wellness
Dentists, physios, gyms — availability and cost are top AI queries, rarely answered in structured format.
Hair & beauty
Salons face strong booking-platform competition and rarely have their own schema or published price lists.
Accommodation
Independent hotels and B&Bs are systematically outcompeted by OTAs in AI answers without schema to assert their own entity.

Questions about the UK SME AI Visibility Report

How visible are UK small businesses in AI search?
+
Based on audits by aivisible.co.uk, the vast majority of UK small businesses have zero measurable AI visibility — they do not appear when customers ask ChatGPT, Perplexity, or Google AI Overviews for recommendations in their sector and area. The businesses that do appear consistently share structured data, answer-first content, and consistent entity information across the web.
What are the most common AI visibility failures for UK SMEs?
+
The five most common failures are: no schema markup at all, missing or incomplete business type identification, credentials not in structured data, no content that directly answers customer AI queries, and inconsistent NAP information across directories and Google Business Profile.
Which UK business sectors have the worst AI visibility?
+
Trades and home services (plumbers, electricians, builders) and independent hospitality (restaurants, cafes, pubs) consistently show the lowest AI visibility rates. These sectors rely heavily on local discovery but have among the lowest rates of structured data implementation.
