Tools · Schema Grader

Is your Schema.org markup any good?

Most schema tools just check whether JSON-LD exists. This one grades it. Enter a URL, get a letter grade per Schema type and overall — required vs. recommended vs. quality, with the specific properties you're missing. Free, no signup.

We fetch the page, pull out every application/ld+json block, and grade each typed entity against a rubric of required, recommended, and quality checks. Usually finishes in 5–15 seconds.
