Priority fixes for webmd.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Harden
HSTS kept for at least a year
Observed: The homepage response did not include a Strict-Transport-Security header.
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 Cloudflare: Enable HSTS under SSL/TLS > Edge Certificates > HTTP Strict Transport Security and raise max-age gradually.
43% of Fitness & Health peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.
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.
78% of Fitness & Health peers do this.

Priority 3 · Accelerate
Modern image formats in use
Observed: The homepage had 41 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.
On Cloudflare: Cloudflare Polish can convert images to WebP.

Priority 4 · Harden
Framing restricted
Observed: The homepage did not send frame-ancestors or X-Frame-Options, so other sites may frame it.
What to do: Send Content-Security-Policy: frame-ancestors 'self' (or a list of trusted origins). X-Frame-Options: SAMEORIGIN covers older browsers.
On Cloudflare: Add the header with a response header transform rule.
58% of Fitness & Health peers do this.
