These four are the schema types that matter for nearly every real website. Service, Product, and Review schema (which our full AEO Score tool also checks) only apply to specific business types - this standalone validator focuses on the universal foundation first.

The most common real cause is invalid JSON syntax inside the script tag - a missing comma or bracket makes the entire block unparseable, so it's treated as absent even though the code is technically present on the page.

Both, to a real degree - it parses the actual JSON-LD and confirms it's valid, structured data of the expected type, not just a text search for a keyword like 'FAQPage' anywhere in the page source.

Yes - any public URL works. Seeing what schema a competitor actually has (or doesn't) is a genuine, honest way to understand a real gap in your own market.

No - schema is necessary infrastructure, not a guarantee. It makes facts about your business machine-readable and verifiable, which measurably helps, but content quality and entity consistency still matter alongside it.

This tool is a focused, single-purpose schema check. The full AEO Score tool runs 21 real checks across schema, on-page fundamentals, AI crawler access, and discoverability files - this is one slice of that larger picture.

It's the real, raw list of every schema type actually found on the page - useful for confirming whether a type you expected but didn't ask about explicitly (like Service or Product) is genuinely there too.

No - it can only fetch genuinely public pages, the same way any AI crawler would encounter your site. A page requiring authentication can't be checked by this or any external tool.

After any real change - a redesign, a CMS migration, a theme update - since these are the real, common moments schema markup silently breaks without anyone noticing in normal visual QA.

Genuinely only blog posts, news content, or similar article-format pages - applying Article schema to a static service page would be inaccurate structured data, which this tool won't reward.

The rate limit exists to keep this a genuinely usable free tool for everyone, not to discourage real, legitimate use - check as many real pages on your own site as you need, spaced across the allowed rate.

The domain checked is recorded for our own internal visibility into how the tool is used, alongside a best-effort location - your specific results aren't shared anywhere.

Organization or LocalBusiness schema first - it's the foundational identity layer everything else builds on, and the one AI systems check most consistently across every query type.

Yes - submit each language version's real URL separately. Schema on your Arabic pages needs to be genuinely present and correct independently, not assumed to carry over from the English version.

AI platforms re-crawl and re-evaluate sources on their own independent schedule, not instantly - a genuine fix here is a real, necessary first step, but seeing it reflected in actual citation can take real time to show up.
