The Schema Markup Most Businesses Are Missing
44% have no Organisation schema. 96% lack Person schema. 52% have FAQ content without FAQPage schema. Under 10% use Speakable. Most businesses have some schema but miss the AI-critical types.
Most UK businesses have some schema markup on their website — but they are missing the types that matter most for AI search. 44% lack Organisation schema. 96% have no Person schema. 52% have FAQ content on their pages without implementing FAQPage schema. Fewer than 10% use Speakable. The problem is not the absence of schema — it is the absence of the right schema.
The schema that matters for AI
Not all schema types are equal for AI visibility. Google's traditional rich results and AI platforms prioritise different schema types. A site might have perfect Product schema and Article schema — earning rich snippets in Google — while completely lacking the Organisation, Person, and FAQPage schema that AI platforms use to decide whether to cite it.
| Schema type | AI impact | Current gap |
|---|---|---|
| Organisation | Entity verification — AI cross-references with GBP, LinkedIn, Crunchbase | 44% of UK SMEs missing |
| Person | Author credibility — 3x citation lift with named, credentialed authors | 96% of UK SMEs missing |
| FAQPage | Answer extraction — 350% citation increase | 52% with FAQ content but no schema |
| Speakable | Content extraction signal — 127% citation increase | Under 10% adoption |
The Organisation schema gap
44% of UK SME websites have no Organisation schema at all. Without it, AI platforms cannot machine-read your business name, type, location, or verify your identity across platforms. The sameAs property — which links to your LinkedIn, GBP, and other profiles — is the entity verification layer that AI uses to build confidence in your brand. No Organisation schema means no verifiable entity.
Organisation schema is the identity foundation. Everything else builds on it. A site with FAQPage and Article schema but no Organisation schema has structured content without a structured identity — the AI knows what the content says but has lower confidence in who is saying it.
The Person schema gap
At just 4% adoption, Person schema is the biggest competitive gap in AI search. Content attributed to a named, credentialed author with Person schema is 3x more likely to be cited than anonymous content. Yet 96% of businesses are leaving this advantage on the table.
Person schema is particularly impactful for:
- Professional services — solicitors, accountants, consultants with verifiable qualifications
- Healthcare — practitioners with medical credentials
- B2B — thought leaders with industry expertise
- Content-heavy sites — blogs, publications, and educational content
The FAQ schema gap
52% of sites in our audit had FAQ content visible on their pages — accordion sections, question-and-answer blocks, support pages — but did not implement FAQPage schema. The content exists. The structure exists. The schema is simply missing.
This is the lowest-effort, highest-impact fix available. If your site already has FAQ content, adding FAQPage schema takes minutes and delivers a 350% citation increase. It does not require rewriting content or redesigning pages — just adding the structured data that tells AI platforms "this page contains questions and answers."
The Speakable gap
Speakable schema is used by fewer than 10% of websites despite delivering a 127% citation increase. It marks specific content sections as suitable for direct extraction — effectively telling AI "cite this paragraph." Most web developers have never heard of it, and popular CMS plugins do not include it.
Priority order for implementation
If your site is missing multiple schema types, implement them in this order:
- Organisation schema — the identity foundation (takes 30 minutes to implement)
- FAQPage schema on existing FAQ content — highest citation impact, lowest effort
- Article + Person schema for content — attribute content to credentialed authors
- Speakable on key pages — mark your most citable paragraphs
- HowTo schema on instructional content — structure step-by-step guides
- BreadcrumbList — signal site structure and topic hierarchy
Quick wins
Most of these fixes are quick wins that require no content changes:
- Organisation schema: 30 minutes to write and add to your homepage
- FAQPage schema on existing FAQ sections: 15 minutes per page
- Person schema for your team: 20 minutes per person
- Speakable on key articles: 10 minutes per page
The total investment to close these gaps is typically a few hours of technical work. The impact — measured in AI citation probability — is substantial and immediate.
