Meta Tags

Weight: 8% of your AX score. This check verifies AI-specific meta tags, discovery link elements, identity links, and OpenGraph metadata in your HTML <head>.

Few AI meta tags

ax-audit checks for 5 AI meta tags. You have fewer than 3. Add the missing ones to your <head>:

<meta name="ai:summary" content="Brief description of this page for AI agents" />
<meta name="ai:content_type" content="website" />
<meta name="ai:author" content="Your Name" />
<meta name="ai:api" content="https://your-site.com/.well-known/openapi.json" />
<meta name="ai:agent_card" content="https://your-site.com/.well-known/agent.json" />

These meta tags give AI agents quick access to page-level metadata without parsing JSON-LD or fetching external files.

No AI meta tags

Your page has none of the 5 AI meta tags. This is a significant penalty (-25 points). Add at least ai:summary, ai:content_type, and ai:author as a starting point. See the code block in the section above.

Missing llms.txt alternate link

Add a <link> element in your <head> pointing to your llms.txt:

<link rel="alternate" type="text/plain" href="/llms.txt" title="LLM-optimized content" />

This allows AI agents parsing HTML to discover your llms.txt without relying on robots.txt or Link headers.

Missing agent.json alternate link

Add a <link> element pointing to your Agent Card:

<link rel="alternate" type="application/json" href="/.well-known/agent.json" title="Agent Card" />

No rel="me" identity links

rel="me" links verify your identity across platforms. They help AI agents connect your site to your profiles on GitHub, Twitter, LinkedIn, etc.:

<link rel="me" href="https://github.com/yourname" />
<link rel="me" href="https://twitter.com/yourname" />
<link rel="me" href="https://linkedin.com/in/yourname" />

This is part of the IndieWeb identity verification standard and is increasingly used by AI agents to verify author identity.

No OpenGraph meta tags

OpenGraph tags (og:title, og:description, etc.) are primarily for social sharing but AI agents also use them as a structured data fallback:

<meta property="og:title" content="Your Page Title" />
<meta property="og:description" content="Page description" />
<meta property="og:url" content="https://your-site.com/page" />
<meta property="og:type" content="website" />
<meta property="og:image" content="https://your-site.com/og-image.png" />
