Public AI visibility report

sublern.proAI visibilityNeeds Work

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

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

Recommended next step

publish an AI guidance file as text or markdown with more than 200 characters, markdown headings, and at least one absolute URL.

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.

// signal breakdown

8 signals AI systems depend on

The homepage resolves, connects, returns HTTP 200 OK, exposes a canonical URL, and is not blocked by robots.txt.

Signal weight

Evidence

robots.txt allows crawler access and includes Sitemap references.

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.

Signal weight

10/10

Pass

Evidence

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

Signal weight

0/15

Fail

Evidence

url: https://sublern.pro/
acceptHeader: text/markdown
status: 500

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

7/10

Warn

Evidence

url: https://sublern.pro/
quality: partial
score: 71

Recommendation

Next step: Shorten the title tag to 70 characters or fewer. Add missing semantic elements: article.

Structured data was found, but it is missing core Organization or WebSite schema, contains invalid JSON-LD, or only uses non-JSON-LD formats.

Signal weight

5/10

Warn

Evidence

url: https://sublern.pro/
quality: partial
hasStructuredData: true

Recommendation

Next step: Prefer valid JSON-LD and include Organization or WebSite schema.org types in valid JSON-LD for clearer AI interpretation.

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

Signal weight

0/5

Fail

Evidence

url: https://sublern.pro/
hasContentSignals: false
hasContentSignalHeader: false

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.
