Public AI visibility report

github.comAI visibilityPoor

This site is difficult for AI tools to read right now.

Key strengths include AI guidance file, while plain-text page access and sitemap need attention.

Recommended next step

make the homepage respond successfully to requests with Accept: text/markdown, either by serving markdown directly or by adding a markdown variant URL with correct content negotiation.

Why monitor after one scan?

AI visibility changes when teams ship new pages, edit pricing or docs, update sitemaps, or change crawler rules. Weekly monitoring catches those silent regressions before answer engines and agents start reading stale or broken signals.

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.

robots.txt contains AI-crawler path blocks 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.

The llms.txt file was found and includes the expected text, length, heading, and URL signals.

Evidence

sitemapUrls: [https://github.com/sitemap.xml]

Recommendation

Next step: Publish a valid XML sitemap at /sitemap.xml and reference it from robots.txt so crawlers and AI systems can discover important URLs.

The homepage could not be fetched with a markdown Accept header.

Signal weight

0/15

Fail

Evidence

url: https://github.com/
acceptHeader: text/markdown
status: 406

Recommendation

Next step: Make the homepage respond successfully to requests with Accept: text/markdown, either by serving markdown directly or by adding a markdown variant URL with correct content negotiation.

The homepage has some semantic HTML signals, but one or more title, metadata, heading, landmark, content, or link text checks need improvement.

Signal weight

6/10

Warn

Evidence

url: https://github.com/
quality: partial
score: 57

Recommendation

Next step: Shorten the meta description to 160 characters or fewer. Use exactly one h1 element and move secondary section titles to h2-h6. Add missing semantic elements: article.

No JSON-LD, Microdata, or RDFa structured data was found on the page.

Signal weight

0/10

Fail

Evidence

url: https://github.com/
quality: none
hasStructuredData: false

Recommendation

Next step: Add JSON-LD structured data with Organization or WebSite schema so AI systems can identify the site owner or website entity.

Content-Signal directive not detected in headers, HTML metadata, or robots.txt.

Signal weight

0/5

Fail

Evidence

Recommendation

Next step: Add the standard directive 'Content-Signal: ai-train=no, search=yes, ai-input=yes' to robots.txt, HTML metadata, or HTTP headers so AI systems can discover content usage preferences.
