Priority fixes for rightmove.co.uk

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 Fastly: Add the header in VCL or a header rule as described in Fastly's HSTS guide.
43% of Real Estate & Property Listings peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

Priority 2 · 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.
77% of Real Estate & Property Listings peers do this.

Priority 3 · 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.
54% of Real Estate & Property Listings 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.
65% of Real Estate & Property Listings peers do this.
