Priority fixes for minkou.jp
Ordered by impact and by how common each practice is among peers.
Priority 1 · Enable
Mobile viewport configured
Observed: The homepage had no viewport meta tag, so phones may render it zoomed out.
Why it matters: Without it, phones render the page at desktop width and shrink it, which makes text tiny and hard to use.
What to do: Add <meta name="viewport" content="width=device-width, initial-scale=1"> and check the layout on small screens.
93% of Ratings & Reviews peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.
Priority 2 · Accelerate
Modern image formats in use
Observed: The homepage had 29 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.
37% of Ratings & Reviews peers do this.
Guide: AVIF, WebP, JPEG, and PNG: Choose the Right Image Format
Priority 3 · Harden
DMARC policy enforces quarantine or reject
Observed: The DMARC policy for minkou.jp was p=none, which asks receivers to take no action on failing mail.
What to do: Publish DMARC with p=none and a reporting address first, fix any legitimate senders that fail SPF or DKIM alignment, then move to quarantine and finally reject.
37% of Ratings & Reviews peers do this.
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.
78% of Ratings & Reviews peers do this.
