Vantage
Where the request came from. Origins serve differently by geography and IP reputation, so an observation is only comparable with another taken from the same place. Everything here is measured from GitHub runners in the US and EU. More- gha-ubuntu
Policy posture
Whether anyone actually decided. Deliberate means robots.txt names AI crawlers by token. Inherited means it names none, so whatever AI policy exists is a side effect of generic rules. Blanket means one rule for everyone. Absent means no robots.txt at all. More

Agent access22.4 / 45
- Answer-surface crawlers allowed. 5 of 11 blocked: GPTBot, ClaudeBot, Google-Extended, Applebot-Extended, meta-externalagent.
- Secondary crawlers allowed. 3 of 12 blocked: CCBot, Amazonbot, Bytespider.
- Serves crawlers the same content. Requesting as GPTBot returned HTTP 403 and 25 bytes, against 203,867 bytes for a browser.
Machine-readable surface9 / 25
- robots.txt published. robots.txt is present and parseable.
- Sitemap declared in robots.txt. robots.txt points crawlers at a sitemap.
- llms.txt published. No /llms.txt.
- agents.md published. No /agents.md.
- Licence terms declared. No RSL License directive and no licence link relation. Reuse terms are undeclared.
- Granular usage preferences declared. robots.txt carries Content-Signal: search=yes,ai-train=no,use=reference. Preferences are stated per use rather than as a single allow or deny.
- Agent card published. No agent card at /.well-known/agent-card.json.
Content structure25 / 30
- Organization schema. Organization JSON-LD lets an agent resolve who publishes this site.
- WebSite schema. WebSite JSON-LD present.
- Additional structured data. No further JSON-LD types on the homepage.
- Readable without JavaScript. 3,925 characters of text in the server response. Most crawlers do not execute JavaScript.

- Dateline declared. Declares a publication date in machine-readable form.
- Authorship declared. Declares an author or creator that an agent can attribute the page to.
How this compares to its peers
A score out of 100 is not information on its own. Against the sites running the same platform and sitting behind the same edge network, it is: this site is behind at least one of its own cohorts, which usually means the gap is its own to close. Cohorts under 25 measured sites are never published, so every comparison here is against a real group.
| Group | Median score | Sites in group | Difference |
|---|---|---|---|
| This site | 56 | 1 | 0 |
| Sites behind Cloudflare | 64 | 1095 | -8.0 |
| The whole index | 61 | 2638 | -5.0 |

Extraction profile
How cheap this page is for a retrieval pipeline to chunk. Recorded and published, deliberately not scored: it describes a shape rather than a pass or a fail, and compressing it into the grade would destroy the useful part.

Content-Signal
A robots.txt directive expressing granular preferences, for example search=yes, ai-train=no, use=reference. Cloudflare writes it into managed robots.txt, so its spread is partly a measure of Cloudflare rather than of publisher intent. Moresearch=yes,ai-train=no,use=reference
Crawler policy
Read from ydparty04.tv/robots.txt. A crawler is listed as blocked when the rules deny it the site root. This operator names 8 AI crawlers explicitly, which means the policy is deliberate rather than inherited from a wildcard rule.

No mark at this score
The embeddable mark starts at grade B, because offering a graphic nobody would put on their own site is a pretence rather than a feature. The list above is the useful version: for most sites the points are concentrated in two or three changes. How the mark works.
The neutral mark above exists and is free to use if you want to show that the site is independently measured whatever the number says.
