structured-data.site-name-missing

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. Info is a best practice: worth doing, rarely urgent, and --no-info leaves it out. Each finding takes 1 point 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.site-name-missing

Or from an assistant, with the MCP tool seo_audit_page:

{
  "url": "https://example.com",
  "rules": [
    "structured-data.site-name-missing"
  ]
}

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

• Infostructured-data.missing-recommendedA structured data item is missing properties Google recommends for richer results.
• Warningstructured-data.invalid-dateDate properties in structured data that are not ISO 8601.
• Infostructured-data.retired-typeThe page has structured data for a rich result Google no longer shows: FAQPage, HowTo, SpecialAnnouncement, ClaimReview, the sitelinks search box's SearchAction, Estimated Salary (Occupation), Learning Video (LearningResource on a VideoObject) or Book Actions (ReadAction, BorrowAction on a Book).
• Warningstructured-data.invalid-valueA structured data value is in a form Google cannot use: a price with a currency symbol or a decimal comma, a currency that is not an ISO 4217 code, a rating outside its scale, a breadcrumb trail with fewer than two items, odd positions or crumbs without a URL, or an availability, itemCondition, eventStatus, eventAttendanceMode or employmentType that is not one of the values Google lists.
• Infostructured-data.relative-urlA URL in JSON-LD (url, image, logo, item, sameAs, ...) is relative. JSON-LD does not resolve these properties against the page URL, and Google documents only absolute URLs.
• Infostructured-data.dangling-idJSON-LD refers to an object by "@id" that no object on the page defines, so a reader of this page gets the id and none of the object's properties.
• Warningstructured-data.paywall-invalidPaywalled content markup Google cannot use: isAccessibleForFree is false but hasPart names no paywalled section, or the section's cssSelector is not a .class selector (warning); no element in the HTML has that class (info). Without it, Google cannot tell a paywall from cloaking.
• Infostructured-data.self-serving-reviewAn Organization or LocalBusiness on its own site carries aggregateRating or review markup about itself. Google shows no review stars for such self-serving reviews, also when a widget adds them.
