Public AI visibility report

signalshield.ioAI visibilityNeeds Work

This site has a useful foundation, but important gaps still limit AI readability.

Key strengths include sitemap and structured data, while plain-text page access and page structure need attention.

Recommended next step

add content negotiation for Accept: text/markdown on the homepage and return a markdown representation with Content-Type: text/markdown.

Keep the HTML response for regular browser requests.

// signal breakdown

8 signals AI systems depend on

The homepage is reachable, but robots.txt contains AI crawler restrictions for GPTBot, ChatGPT-User, ClaudeBot, Claude-Web, PerplexityBot, and Google-Extended.

Recommendation

Next step: Review AI crawler Disallow rules and keep only the paths that should be excluded from AI crawler access; serve a non-empty HTML homepage with a canonical link tag.

The robots.txt file was found, but it contains formatting issues.

Recommendation

Next step: Fix robots.txt syntax issues so each rule uses Field: value format, directives appear under a User-agent, and Sitemap entries use absolute URLs.

The llms.txt file exists but is missing one or more expected quality signals.

Recommendation

Next step: Publish /llms.txt as text or markdown with more than 200 characters, markdown headings, and at least one absolute URL.

The sitemap.xml file is valid and contains URL entries.

The homepage returned HTML when requested with Accept: text/markdown, so the server appears to ignore markdown content negotiation.

Recommendation

Next step: Add content negotiation for Accept: text/markdown on the homepage and return a markdown representation with Content-Type: text/markdown. Keep the HTML response for regular browser requests.

The homepage HTML is missing important title, metadata, structure, content, or link text signals.

Recommendation

Next step: Shorten the meta description to 160 characters or fewer. Add exactly one h1 element that describes the page topic. Add missing semantic elements: main, article, nav, footer. Add visible body copy after script and style removal so the page has at least 200 words.

Valid JSON-LD structured data was found with core Organization or WebSite schema.org types.

Recommendation

Next step: Consider adding robots noai/noimageai directive, Content-Signal robots.txt directive so AI systems can consistently discover content usage preferences across robots.txt, HTTP headers, and HTML metadata.
