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

- Serves crawlers the same content. A crawler and a browser receive comparable responses.
Machine-readable surface16 / 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. /llms.txt is served and its structure matches the spec.
- 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. No Content-Signal directive. Policy is expressed only as allow or deny.
- Agent card published. No agent card at /.well-known/agent-card.json.
Content structure13 / 30
- Organization schema. No Organization JSON-LD. Agents cannot reliably attribute this site to an entity.
- WebSite schema. No WebSite JSON-LD.
- Additional structured data. Also declares: WebPage.

- Single top-level heading. 1 h1 element found.
- Semantic landmarks. Uses main, nav.
- Dateline declared. No machine-readable date. An agent cannot tell how current this page is.
- Authorship declared. No declared author. An agent quoting this page has nobody to credit.
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 at or ahead of every cohort it belongs to, which usually means the ceiling is the platform rather than the site. 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 | 73 | 1 | 0 |
| Sites behind Cloudflare | 64 | 1132 | 9.0 |
| The whole index | 61 | 2567 | 12.0 |
What would move this score

Extraction profile

Crawler policy
Read from arkoselabs.com/robots.txt. A crawler is listed as blocked when the rules deny it the site root. This operator names 1 AI crawler 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.
