structured-data.invalid-json

What to change

A 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. An error is a problem that keeps a page out of search or out of answers, or breaks how it shows there. Each finding takes 15 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.invalid-json

Or from an assistant, with the MCP tool seo_audit_page:

{
  "url": "https://example.com",
  "rules": [
    "structured-data.invalid-json"
  ]
}

To leave it out of an audit, pass --disable structured-data.invalid-json on the command, or disableRules: ["structured-data.invalid-json"] to a tool.
