Priority fixes for passeportsante.net
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
HTML compressed
Observed: The homepage HTML (404 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.
90% of Fitness & Health peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

Priority 2 · 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.
62% of Fitness & Health peers do this.
Priority 3 · Accelerate
HTTP/3 advertised
Observed: The homepage did not advertise HTTP/3 through an Alt-Svc header.
What to do: Turn on HTTP/3 at your CDN. Browsers fall back to HTTP/2 automatically, so the risk is low.
29% of Fitness & Health peers do this.
Priority 4 · Recover
Nameservers spread across providers
Observed: All nameservers for passeportsante.net belong to a single operator.
What to do: Treat this as an advanced step. Add a secondary DNS provider through zone transfers or a multi-provider setup, then test changes carefully, since both providers must stay in sync.
9.9% of Fitness & Health peers do this.
