Schema Score
JSON-LD SEO analyzer with a 0–100 completeness score
Schema Score analyzes the JSON-LD structured data on any page in one click. It validates required and recommended fields across 16+ schema types, gives a 0–100% completeness score, flags invalid JSON with line and column, warns about duplicate types, and links straight to Google's Rich Results Test. 100% local, no data collected. Now bilingual (English and Portuguese, auto-detected). Built for SEOs and developers who want to audit structured data fast.
Hey hunters 👋
I'm Daniel, a web developer and SEO. I built Schema Score because I kept manually checking structured data across client sites, and the existing tools either lived on a separate page or buried the answer.
This one is a single click. It tells you how complete your JSON-LD is (0–100%), what required fields are missing per schema type, catches invalid JSON before Google does, and jumps you straight to the Rich Results Test. Everything runs locally, nothing is tracked.
It just shipped bilingual (English and Portuguese, auto-detected, with a manual toggle).
Would love your feedback on which schema types to support next.
