Priority fixes for booknet.ua

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

1. Priority 1 · Accelerate

   Static files cached for 30 days or more

   Observed: A same-site stylesheet or script was cacheable for 3 days, short of the 30-day benchmark.

   Why it matters: Returning visitors and later page views reuse cached files instead of downloading them again.

   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.

   49% of Literary & Knowledge peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

2. Priority 2 · Accelerate

   No render-blocking scripts in <head>

   Observed: The homepage <head> loaded 11 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.

   48% of Literary & Knowledge peers do this.

3. Priority 3 · Accelerate

   Modern image formats in use

   Observed: The homepage had 80 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.

   31% of Literary & Knowledge peers do this.

4. Priority 4 · Accelerate

   HTTP/3 advertised

   Observed: The homepage did not advertise HTTP/3 through an Alt-Svc header.

   What to do: Turn on HTTP/3 at your CDN. Browsers fall back to HTTP/2 automatically, so the risk is low.

   47% of Literary & Knowledge peers do this.
