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 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 Content ratio: 5.1% (3136 content chars / 61668 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 8 semantic elements, 74 divs (ratio: 10%)

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.

The blind spot

## You optimized for Google for fifteen years. Now half your traffic decides whether to visit you *before it ever loads your page* — inside an AI answer.

Vibe coders ship fast and skip the boring parts. Kleos is an SEO & AEO scanner that finds the gaps hurting your ranking and keeping you out of ChatGPT, Claude and Perplexity — in one scan.

Measured, not vibes: [Pew Research (2025)](https://www.pewresearch.org/short-reads/2025/07/22/google-users-are-less-likely-to-click-on-links-when-an-ai-summary-appears-in-the-results/) — clicks on regular results nearly halve when an AI summary appears.

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.
