Running this check for a client?

A check shows a gap. Closing it is the off-page work we do for SEO agencies, under the agency's name. Send us one client domain: we run the citation test and email you what came back. No charge, and your client is never contacted.

What is schema markup?

Schema markup (JSON-LD) is structured data you add to a page so machines understand it. It tells search engines and AI answer engines what your content means, not just what it says.

Why it matters for AI visibility

Answer engines like ChatGPT, Perplexity and Google AI Overviews prefer sources they can parse with confidence. Clear FAQ, Organization and Product schema makes your pages easier to quote, which means more citations and more visibility.

Which schema should you add first?

Add FAQPage to question-and-answer pages and Organization to describe your organization. Then add Product or Article depending on the page.
