Priority fixes for flashcourier.com.br
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
HTML compressed
Observed: The homepage HTML (339 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 · 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.
61% of Postage & Courier Services peers do this.
Priority 4 · Enable
Social preview image set
Observed: The homepage had no og:image, so shared links may show without a preview image.
What to do: Add Open Graph tags, including og:image with a 1200 x 630 image.
50% of Postage & Courier Services peers do this.
