AI systems — including ChatGPT, Claude, and Perplexity — weight source credibility when deciding whether to cite content. Anonymous content with no identified author, team, or organization scores lower on the E-E-A-T signals (Experience, Expertise, Authoritativeness, Trustworthiness) that both Google and LLMs use to rank citation-worthy sources. Missing Person or Organization schema (schema-org vocabulary) means structured authority data is absent from the machine-readable layer entirely. For AI-generated answers, attribution-free content is harder to trust and less likely to appear in citations — regardless of content quality.
High because absent authorship signals directly reduce AI citation rates; content without traceable authority is systematically deprioritized by LLMs evaluating source trustworthiness.
Add at least one authorship signal to your site. An about page with real names and roles is the highest-ROI option. Pair it with Organization schema in your root layout.
// app/layout.tsx — add to <head> via next/script or a JSON-LD component
<script type="application/ld+json" dangerouslySetInnerHTML={{ __html: JSON.stringify({
"@context": "https://schema.org",
"@type": "Organization",
"name": "Your Company Name",
"url": "https://example.com",
"founder": {
"@type": "Person",
"name": "Jane Smith"
}
})}} />
For blog posts, add a visible byline and a matching author field in Article/BlogPosting schema. Both the human-visible signal and the machine-readable schema contribute independently to AI citation scoring.
ID: geo-readiness.authority-expertise.authorship-signals
Severity: high
What to look for: Count all authorship signals in the codebase. Check for: author bylines on blog or content pages, a team page with real names, an about page identifying the creators, Person or Organization schema with author data, visible "written by" or "maintained by" indicators. Enumerate each signal type found and where it appears.
Pass criteria: Count all distinct authorship signal types. At least 1 of the following 5 signal types must be present: (1) author bylines on blog/content pages, (2) a team or about page with real names and roles, (3) Person schema with author data, (4) Organization schema with a real company name, (5) visible "written by" or "maintained by" indicators. Report: "X of 5 authorship signal types found: [list types]".
Fail criteria: 0 of 5 authorship signal types found. The site gives no indication of who created it, who maintains it, or who is behind the product. Anonymous content with no attribution.
Skip (N/A) when: API-only projects with no content beyond auto-generated API docs.
Detail on fail: "0 of 5 authorship signal types found — no about page, no team page, no bylines on blog posts, no author schema, no attribution text. Anonymous content is harder for AI systems to trust." or "Blog posts exist but have no author attribution — 0 of 5 signal types present"
Remediation: AI systems consider authorship when evaluating source credibility. Add attribution:
// About page or footer
<p>Built by [Your Name/Team], [brief credentials or background].</p>
// Blog post byline

An about page with real names and relevant background is the strongest signal.
