Now see if AI actually recommends you
The free Eudoxia Score check asks AI assistants the questions your customers ask, and shows who they recommend instead of you.
Questions
What does this check?
It reads the JSON-LD structured data on the page, reports blocks that can't be parsed, lists the schema types found, and checks the key fields for common types such as LocalBusiness, Organization, FAQPage, Article, Product, Event and BreadcrumbList.
Does it replace Google's Rich Results Test?
No. It's a quick, plain-English check focused on what matters for AI assistants. Use Google's Rich Results Test and the Schema Markup Validator for full validation.
It found microdata but no JSON-LD. Is that a problem?
Microdata works, but JSON-LD is easier to maintain and is what Google recommends. Our schema and FAQ generators create JSON-LD.
