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.

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.

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.

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 main content appears late in the HTML document. AI agents may give more weight to content that appears early.

How to implement

Restructure your HTML so that <main> or <article> content appears before sidebars and supplementary content.

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).

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>.

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.
