Priority fixes for clickpost.jp
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
HTML compressed
Observed: The homepage HTML (68 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.
85% of Postage & Courier Services peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

Priority 2 · 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.
74% of Postage & Courier Services peers do this.
Priority 3 · Harden
DMARC policy enforces quarantine or reject
Observed: No DMARC record was found at _dmarc.clickpost.jp.
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.
52% of Postage & Courier Services peers do this.
Priority 4 · Enable
XML sitemap discoverable
Observed: No sitemap was listed in robots.txt or found at /sitemap.xml.
What to do: Generate an XML sitemap of canonical URLs, reference it in robots.txt and submit it in Google Search Console.
69% of Postage & Courier Services peers do this.
