Priority fixes for zetteria.jp
Ordered by impact and by how common each practice is among peers.
Priority 1 · Harden
HTTP requests move to HTTPS
Observed: A request to http://www.zetteria.jp/ was not redirected to HTTPS.
Why it matters: Visitors who type the address or follow an old link start on unencrypted HTTP. A redirect moves them to the encrypted site before any cookies or form data are sent.
What to do: Add a permanent (301 or 308) redirect from every http:// URL to the same https:// URL at your CDN, load balancer or web server.
On Amazon CloudFront: Set the viewer protocol policy of each cache behaviour to Redirect HTTP to HTTPS.
96% of Food & Grocery Delivery peers do this. Limit: Measured for the homepage only, from one location, at the time of the check.
Priority 2 · Accelerate
HTML compressed
Observed: The homepage HTML (12 KB) was delivered without gzip, Brotli or zstd compression.
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.
90% of Food & Grocery Delivery 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.
93% of Food & Grocery Delivery 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.
91% of Food & Grocery Delivery peers do this.
