Priority fixes for flash.pt
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
HTTP/2 negotiated
Observed: The TLS handshake selected http/1.1 instead of HTTP/2.
Why it matters: HTTP/2 sends many files over one connection, which speeds up pages with lots of images, styles and scripts.
What to do: Enable HTTP/2 on your CDN or server. Most CDNs do this by default.
94% of News & Media peers do this. Limit: Certificate and protocol were observed from one vantage point; CDNs can present different certificates by region.
Priority 2 · Accelerate
Static files cached for 30 days or more
Observed: A same-site stylesheet or script was cacheable for 7 days, 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.
Priority 3 · Accelerate
Modern image formats in use
Observed: The homepage had 111 images and none used WebP or AVIF.
What to do: Serve WebP or AVIF with a JPEG or PNG fallback, either through an image CDN or by generating both formats at build time.
44% of News & Media peers do this.
Guide: AVIF, WebP, JPEG, and PNG: Choose the Right Image Format
Priority 4 · Enable
Canonical URL declared
Observed: The homepage did not declare a canonical URL.
What to do: Add a self-referencing canonical link to every indexable page, using the final https:// URL.
89% of News & Media peers do this.
