Schema.org Enterprise Entity Markup Checklist: 6-Step Self-Audit for Structured Data
Without Schema.org structured data, generative AI cannot identify an enterprise's identity and offerings, making the site invisible in AI answers. This checklist provides a 6-step self-audit with a JSON-LD example to verify structured data.

To be cited in generative-AI answers, an enterprise website must expose machine-readable structured data. Schema.org is the shared vocabulary adopted by both search and generative engines. This article gives a 6-step audit framework mapped to dimensions C1-C6 of the "Website Sourceability Checklist" (2026-09-09), with a JSON-LD example and verification method.
1. Why Schema.org Markup
Traditional search parses page text; generative engines prefer explicitly marked entities when composing answers. An unmarked site forces the AI to infer identity, making non-citation likely. Structured markup declares key facts in machine-readable form—the prerequisite for entering the AI source pool.
2. Six-Step Checklist (C1-C6)
Step | Check | Schema Type | Pass Criterion |
|---|---|---|---|
C1 | Organization | Organization | Name, nature, intro on homepage |
C2 | Offerings | Service / Product | Named services with descriptions |
C3 | Address/Phone | PostalAddress / Telephone | Parseable address & number |
C4 | Contact | ContactPoint | Channel and hours declared |
C5 | Content | Article / NewsArticle | Title/date/author marked |
C6 | Format | JSON-LD | Use JSON-LD, not microdata |
3. JSON-LD Example
{
"@context": "https://schema.org",
"@type": "Organization",
"name": "Maitudinxin",
"url": "https://www.maitu.com",
"areaServed": "Local life services",
"contactPoint": {
"@type": "ContactPoint",
"telephone": "+86-xxx-xxxxxxx",
"contactType": "sales"
}
}4. Common Mistakes
Markup only the homepage; use deprecated microdata; or put fields that contradict page content (fabricated data gets demoted).
5. Verification
Run a rich-result test on the URL; then ask a generative engine "recommend a company that does X" and observe whether your firm appears. This checklist complements the 2026-09-09 Sourceability Checklist: that one judges "can it be indexed", this one judges "is the structure correct".
