What we find on almost every site we check

When we audit local business websites, the same gap shows up on nearly every one - and schema is the worst of it.

Every single one had 5-star Google reviews - and not one had the review schema that makes star ratings show up in search.

Most had no structured data at all - one scored an F, with zero schema on the entire site.

Almost none had FAQ or question-based content, so AI engines had nothing to cite.

When the schema was there, it often didn't match the visible content - which gets it ignored.

We hand-verify every finding before we report it, because audit tools - ours included - throw the occasional false positive. The numbers above are issues we confirmed in the page source, not just tool flags.

Schema markup is structured data - code that spells out what a page is about in a format machines read perfectly. Get it right and you become eligible for rich results and AI citations. Leave it out and engines have to guess.

What the schema checker finds

RankBuddy reads the structured data on your page and reports:

Which schema types are present - LocalBusiness, Organization, FAQPage, Article, Product, Service, Person, and more.
What's missing - the schema types your kind of page should have but doesn't.
Whether it matches your content - schema that contradicts what's visible on the page gets ignored or penalized.

Why schema matters more in 2026

Structured data was always good for SEO. Now it's also one of the clearest signals that decides whether ChatGPT, Perplexity, and Google AI Overviews will cite your business. AI engines lean on schema to confirm what a page is and who it's about - and most sites still don't have it, which is exactly the opening for the ones that do.

From "missing schema" to pasted-in fix

Finding out you're missing LocalBusiness schema doesn't help much if you then have to hand-write JSON-LD. RankBuddy writes it for you - populated with your real business details - so adding schema is a copy and paste. Want the full picture? Run a free SEO audit or check your AI visibility.

Schema markup questions

What is a schema markup checker?

A schema markup checker reads the structured data (usually JSON-LD) on a page and tells you which schema types are present, whether they are valid, and what is missing. Schema is the code that tells Google and AI engines exactly what your business, products, reviews, and FAQs are.

How do I check if my website has schema markup?

Paste your URL into RankBuddy. It detects the schema on your page, lists the types it found (like LocalBusiness, Organization, FAQPage, or Article), and flags the ones you should have but do not. You do not need to read any code.

Why does schema markup matter for SEO and AI?

Schema helps search engines show rich results and helps AI systems understand and cite your business accurately. Pages with clear structured data are markedly more likely to be surfaced in AI answers, because the engine can trust what the page is about. Schema that matches your visible content is one of the strongest AI-visibility signals.

Can RankBuddy write the schema for me?

Yes. On paid plans, RankBuddy generates the exact JSON-LD for your business - filled in with your details - so you can copy and paste it into your page head. No coding required.
