Priority fixes for myheritage.se

Ordered by impact and by how common each practice is among peers.

1. Priority 1 · Harden

   HSTS kept for at least a year

   Observed: Strict-Transport-Security was sent with a max-age of 30 days, below the one-year benchmark.

   Why it matters: HSTS tells browsers to use HTTPS for your host on every later visit, which removes the window where a first HTTP request can be intercepted.

   What to do: Send Strict-Transport-Security on HTTPS responses. Start with a short max-age (for example 300 seconds), confirm every subdomain works over HTTPS, then raise it in steps to 31536000. Add includeSubDomains only when all subdomains are HTTPS. HSTS preload is optional and hard to undo; hstspreload.org itself does not recommend it by default.

   On Amazon CloudFront: Attach a response headers policy with Strict-Transport-Security to each distribution.

   43% of Family & Heritage peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

2. Priority 2 · 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.

   67% of Family & Heritage peers do this.

3. Priority 3 · Accelerate

   Modern image formats in use

   Observed: The homepage had 6 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.

   25% of Family & Heritage peers do this.

4. Priority 4 · 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.

   On Amazon CloudFront: Select HTTP/3 in the distribution's supported HTTP versions.

   31% of Family & Heritage peers do this.
