Your site doesn't have an llms.txt file. This is the emerging standard for helping AI agents understand your site structure.
How to implement
Create an /llms.txt file following the llmstxt.org specification. Include a site description and links to your key pages.
Your page doesn't use <article> or <main> elements. These semantic containers help AI agents identify the primary content area and ignore navigation, sidebars, and footers.
How to implement
Add a <main> element around your page's primary content, and use <article> for self-contained content blocks like blog posts or product descriptions.
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.
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.
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.
Some images lack descriptive alt text. Good alt text helps AI agents understand image content and context.
How to implement
Add descriptive alt attributes to all images. Describe what the image shows, not just 'image' or 'photo'. For decorative images, use alt="" (empty).
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.
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.
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 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.
