Priority fixes for ddnavi.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
HTML compressed
Observed: The homepage HTML (49 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.
On Amazon CloudFront: Enable Compress objects automatically on the cache behaviour.
94% of Online Publishing peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

Priority 2 · Enable
Mobile viewport configured
Observed: The homepage had no viewport meta tag, so phones may render it zoomed out.
What to do: Add <meta name="viewport" content="width=device-width, initial-scale=1"> and check the layout on small screens.
96% of Online Publishing peers do this.
Priority 3 · Accelerate
Modern image formats in use
Observed: The homepage had 53 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.
38% of Online Publishing peers do this.

Priority 4 · Accelerate
No render-blocking scripts in <head>
Observed: The homepage <head> loaded 1 external script 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.
45% of Online Publishing peers do this.
