structured-data.missing-context
A JSON-LD item has no @context or a context other than schema.org.
What to change
Set "@context": "https://schema.org" on every top-level JSON-LD object.
The documentation on developers.google.comA finding of this rule on a page carries the exact edits for that page: the markup it quotes, and what to write instead.
When it runs
Runs on every SEO audit: of a page, a crawl, a build directory or HTML. A warning is a problem that costs a page ranking, clicks or citations. Each finding takes 5 points off the page's score.
The severity here is the rule's usual one: a finding can be raised or lowered when the page gives a reason.
Run it, or skip it
Check a page for this rule alone, after a fix for instance:
npx @rivi-software/agentic-seo-check audit https://example.com --rule structured-data.missing-context
Or from an assistant, with the MCP tool seo_audit_page:
{
"url": "https://example.com",
"rules": [
"structured-data.missing-context"
]
}
To leave it out of an audit, pass --disable structured-data.missing-context on the command, or disableRules: ["structured-data.missing-context"] to a tool.
