This grade belongs to zerohour.uk. It is based on a bounded sample of up to 3 connected public pages plus public evidence. It is not a grade for any one page.

Automated EcoMark v3 approximation using technical crawl evidence, DNS, public policy/identity signals and a Green Web hosting check. Browser Run was blocked or incomplete, so the normal public HTML response was used instead. Analysis quality: good.

Algorithm v3 · Raw evidence

Improve

Start with these changes.

1

efficiency

Add long-lived cache headers to versioned static assets.

Lighter pages consume less bandwidth and device work and remain usable on slower connections.

2

sovereignty

Avoid concentrating most third-party delivery in one provider ecosystem.

A more portable and less concentrated stack gives organisations more control over technology and jurisdiction.

3

privacy

Move commonly used assets and services first-party where practical.

Minimising tracking and third-party disclosure reduces profiling and unnecessary visitor data exposure.
