Priority fixes for seikyoonline.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
HTML compressed
Observed: The homepage HTML (99 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.
97% of News & Media 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.
98% of News & Media peers do this.
Priority 3 · Accelerate
HTTP/2 negotiated
Observed: The TLS handshake selected HTTP/1.1 instead of HTTP/2.
What to do: Enable HTTP/2 on your CDN or server. Most CDNs do this by default.
On Amazon CloudFront: Choose HTTP/2 (or HTTP/2 and HTTP/3) as supported versions on the distribution.
94% of News & Media peers do this.
Priority 4 · Enable
robots.txt published
Observed: No robots.txt file was returned at the site root.
What to do: Publish /robots.txt with any crawl rules you need and a Sitemap: line pointing to your XML sitemap.
98% of News & Media peers do this.
