Well-known endpoints AI agents look for. Detected here means an agent can discover and connect to your service automatically.

What we measured Content requires JavaScript rendering

Your page requires JavaScript to render content. Most AI agents don't execute JavaScript, so they see an empty page.

How to implement

Use server-side rendering (SSR) or static site generation (SSG) to ensure content is available in the initial HTML response.

Paste into a coding agent to make the fix

What we measured No Markdown for Agents support detected

Your site doesn't support Markdown for Agents. This Cloudflare standard lets AI agents request content in markdown format, reducing token usage by ~80%.

How to implement

Implement one or more: (1) Respond to Accept: text/markdown with markdown content. (2) Serve .md URLs (e.g., /page.md). (3) Add <link rel="alternate" type="text/markdown"> tags. (4) Add Link HTTP headers for markdown discovery.

Paste into a coding agent to make the fix

What we measured No sitemap found

No sitemap found. A sitemap helps AI agents discover all pages on your site.

How to implement

Create a /sitemap.xml listing all your public pages. Most CMS platforms can generate this automatically.

Paste into a coding agent to make the fix

What we measured Content ratio: 0.7% (1747 content chars / 257996 HTML bytes)

Your page has a low ratio of actual content to total HTML. Much of the page weight is markup, scripts, or styles rather than content.

How to implement

Move CSS to external stylesheets, remove inline styles, minimize JavaScript, and ensure the HTML focuses on content structure.

Paste into a coding agent to make the fix

What we measured 3 semantic elements, 267 divs (ratio: 1%)

Your page relies heavily on <div> elements. Semantic elements like <section>, <nav>, <header>, <footer>, and <aside> provide meaningful structure for AI agents.

How to implement

Replace generic <div> containers with appropriate semantic elements. Use <section> for thematic groups, <nav> for navigation, <header>/<footer> for page/section headers and footers.

Paste into a coding agent to make the fix

What we measured No Content-Signal found (robots.txt or HTTP headers)

No Content-Signal directives found. These tell AI agents how they may use your content (search indexing, AI input, training data). The recommended location is robots.txt.

How to implement

Add Content-Signal to your robots.txt: User-agent: *\nContent-Signal: search=yes, ai-input=yes, ai-train=no. You can also add it as an HTTP header on markdown responses.

Paste into a coding agent to make the fix

What we measured no <h1>

Your heading structure has issues (skipped levels or multiple h1 tags). A clean hierarchy helps AI agents understand content organization.

How to implement

Ensure you have exactly one <h1> per page, and headings follow sequential order: h1 > h2 > h3. Don't skip levels (e.g., h1 directly to h3).

Paste into a coding agent to make the fix

What we measured 2/3 OG tags present

Missing or incomplete Open Graph tags. OG tags help AI agents (and social platforms) understand your page title, description, and image.

How to implement

Add og:title, og:description, and og:image meta tags to your page's <head>.

Paste into a coding agent to make the fix

What we measured 116/1104 elements with inline styles (10.5%)

Many elements have inline style attributes. These add noise for AI agents extracting content.

How to implement

Move all inline styles to CSS classes in your stylesheet. Use utility CSS frameworks like Tailwind if you need many unique styles.

Use our API to get this programmatically (coming soon)

This JSON is for internal use — unlike the Markdown and llms.txt files, it's not meant to be uploaded to your site. Save it as a baseline to track your score over time, share it with your dev team, or integrate it into your CI/CD pipeline.

Want a second opinion?

Cloudflare runs a free scanner too, and it asks a different question. It scores what your site publishes for agents to call — MCP server cards, Agent Skills, API catalogs, DNS records. We score whether an agent can reach, read and understand your content. A site can do well on one and poorly on the other, so expect two different numbers: they are answers to two different questions, and both are worth knowing.
