Why structured data counts twice
For classic SEO, structured data is what makes a page eligible for rich results: the star ratings, FAQ accordions, and breadcrumbs that make a listing stand out. A page without it can still rank, but it ranks as plain text and doesn't get the enhancements that lift click-through.
For GEO, structured data does something subtler but increasingly important: it removes ambiguity for an AI engine. Instead of inferring that a block of text is a product with a price, the engine reads it stated explicitly in JSON-LD, which makes the page safer to summarise and cite. seo·check scores structured data in both contexts because it pays off in both.
What the check tells you
seo·check looks at the served HTML for JSON-LD and marks the check pass or fail, then factors it into both your SEO and GEO category scores so a page with none shows up as a clear, fixable gap with a one-line reason. It's the difference between a page a machine has to interpret and one that introduces itself.
As with the rest of the audit, it's a read-only check: seo·check tells you whether your structured data is there and counts it toward your scores, but it can't edit your markup. You add or correct it on your own site, then re-run to confirm it's detected.
Page with structured data vs. without
| No structured data | JSON-LD present | |
|---|---|---|
| Search engine read | Plain text, must infer | Page type stated explicitly |
| Rich results | Unlikely | Eligible (ratings, FAQ, breadcrumbs) |
| AI engine parsing | Guesswork | Confident, unambiguous |
| seo·check SEO score | Flagged gap | Counts in your favour |
| seo·check GEO score | Flagged gap | Counts in your favour |
frequently asked
What kind of structured data does seo·check check for?
It detects JSON-LD, the format Google and AI engines prefer, and reports whether your page carries it, then folds that into both your SEO and GEO scores.
Why does structured data matter for AI search specifically?
It tells an AI engine what the page is without it having to guess from raw HTML, which makes the page easier to parse and safer to cite. That's why seo·check counts it in the GEO score as well as the SEO one.
Does seo·check fix or generate my structured data?
No. It's a checker: it detects whether JSON-LD is present and scores it, but it won't write markup for you. You add or correct it on your own site, then re-run the check.
Is the structured data check free?
Yes. It's part of the free report, with no account or paid tier.
