How many websites pass the Jsonld Syntax check?
Based on 596 audited sites · Updated 2026-07-16
95% confidence interval: 48.3%–56.3%
Why This Matters
LLM Discoverability
Syntactically invalid JSON-LD is silently discarded by parsers; even well-intentioned structured data provides zero benefit to AI systems if the underlying JSON cannot be parsed.
SEO Impact
Google's Rich Results Test rejects invalid JSON-LD; syntax errors mean no rich results are eligible, negating the investment made in adding structured data.
What To Do Next
47.7% of audited sites need attention on jsonld syntax (284 of 596 sites are warning or failing).
- Prioritize jsonld syntax on templates that create many URLs, because one template fix can improve a large share of structured data.
- After changing the page, re-run the audit and compare the observed value for this check instead of relying on visual inspection alone.
- Use the 52.3% pass rate as a benchmark: if your site fails here, passing the check moves it closer to the visible majority of crawlable, AI-readable pages.
