Priority fixes for visir.is

Ordered by impact and by how common each practice is among peers.

1. Priority 1 · Accelerate

   HTML compressed

   Observed: The homepage HTML (591 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.

2. Priority 2 · Harden

   TLS 1.3 negotiated

   Observed: The TLS connection negotiated TLSv1.2.

   What to do: Enable TLS 1.3 on your CDN or server. Keep TLS 1.2 available for older clients unless you have checked your audience.

   93% of News & Media peers do this.

3. Priority 3 · Accelerate

   Static files cached for 30 days or more

   Observed: A same-site stylesheet or script was cacheable for 0 seconds, short of the 30-day benchmark.

   What to do: Give versioned (fingerprinted) CSS, JavaScript, fonts and images Cache-Control: public, max-age=31536000, immutable, and change the file name whenever the content changes.

   60% of News & Media peers do this.

4. Priority 4 · Harden

   HSTS kept for at least a year

   Observed: The homepage response did not include a Strict-Transport-Security header.

   What to do: Send Strict-Transport-Security on HTTPS responses. Start with a short max-age (for example 300 seconds), confirm every subdomain works over HTTPS, then raise it in steps to 31536000. Add includeSubDomains only when all subdomains are HTTPS. HSTS preload is optional and hard to undo; hstspreload.org itself does not recommend it by default.

   35% of News & Media peers do this.
