How Many Websites Use JSON-LD Structured Data?
46% of the websites we scanned carry JSON-LD structured data on their homepage.
The other 54% carry no JSON-LD at all. Markup written as Microdata or RDFa is not counted, so adoption of structured data in any form is somewhat higher.
Based on 6,586 homepages of public websites (Tranco ranks 1,000 to 100,000, drawn at random), scanned 5 to 12 November 2026. See the full edition.

What it means
Why this number matters
Structured data is machine-readable markup, usually JSON-LD, that tells search engines what a page is about: the organization behind it, a product, an article, its FAQs.
Google uses structured data for rich results and to understand which entity a site belongs to. A homepage without any leaves search engines and AI answers to guess the organization's name, logo and profiles.
Check your own site: the free Structured Data Validator reads the JSON-LD on one of your pages and checks each node.
Named groups
How specific groups of sites compare
Our crawl studies measure the same topic on small, named lists of sites, with their own check and method, so their shares are not directly comparable to the figure above.
- Article and FAQPage structured data among public SEO and web-performance guide articles from software vendors and developer publications
58% of the 33 public SEO and web-performance guide articles from software vendors and developer publications publish Article or FAQPage structured data on the page itself. (n = 33)
- Article and FAQPage structured data among public B2B SaaS homepages
5% of the 44 public B2B SaaS homepages publish Article or FAQPage structured data on the page itself. (n = 44)
Methodology
How this was measured
Scanned the homepage of each site in KinetixSEO's research sweep, a seeded random draw of public sites, between Nov 5, 2026 and Nov 12, 2026 with one unchanged version of the scanner, and counted the 6586 distinct sites on which the "No structured data found" check could run. A site counts once however often it was scanned, and counts as affected if any of its scans showed the issue.
The draw, its seed and the scanner version are public on the edition page, so anyone can redraw the same sites. Only aggregate counts are published — no per-site result.
Every edition
Edition history
Each edition is a new random draw of sites, so a change between editions is partly sampling noise.
| Edition | Share | Sample size |
|---|---|---|
| November 2026 | 46% | n = 6,586 |
| October 2026 | 48% | n = 3,028 |
