Priority fixes for bluewin.ch
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
HTML compressed
Observed: The homepage HTML (1956 KB) was delivered without gzip, Brotli or zstd compression.
Why it matters: Compression usually shrinks HTML several times over, so the first bytes of the page arrive sooner on slow connections.
What to do: Enable Brotli or gzip for text responses (HTML, CSS, JavaScript, JSON, SVG) at the CDN or origin.
97% of News & Media peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

Priority 2 · Harden
DMARC policy enforces quarantine or reject
Observed: The DMARC policy for bluewin.ch was p=none, which asks receivers to take no action on failing mail.
What to do: Publish DMARC with p=none and a reporting address first, fix any legitimate senders that fail SPF or DKIM alignment, then move to quarantine and finally reject.
37% of News & Media peers do this.
Priority 3 · Accelerate
No render-blocking scripts in <head>
Observed: The homepage <head> loaded 2 external scripts without async or defer.
What to do: Add defer to scripts that need the DOM, async to independent ones such as analytics, or move them to the end of the body.
On Next.js: Use the next/script component with an appropriate loading strategy.
42% of News & Media peers do this.

Priority 4 · Enable
Structured data present
Observed: The homepage had no JSON-LD structured data.
What to do: Add JSON-LD for your organization and main content types, then test it with Google's Rich Results Test.
76% of News & Media peers do this.
