Priority fixes for heraldo.es
Ordered by impact and by how common each practice is among peers.
Priority 1 · Enable
XML sitemap discoverable
Observed: No sitemap was listed in robots.txt or found at /sitemap.xml.
Why it matters: A sitemap helps search engines find new and updated pages, especially on large or frequently updated sites.
What to do: Generate an XML sitemap of canonical URLs, reference it in robots.txt and submit it in Google Search Console.
87% of News & Media peers do this. Limit: Only the standard location was requested, once, at the time of the check.

Priority 2 · Harden
HSTS kept for at least a year
Observed: The homepage response did not include a Strict-Transport-Security header.
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.
35% of News & Media peers do this.
Priority 3 · Harden
Certificate lifetime of 100 days or less
Observed: The certificate from Amazon had a 197-day validity period, longer than the 100-day maximum that applies from March 2027.
What to do: Move to automated issuance and renewal now, while you still have time to test it.
66% of News & Media peers do this.
Priority 4 · Harden
Content Security Policy present
Observed: The homepage response did not include a Content-Security-Policy header.
What to do: Start with Content-Security-Policy-Report-Only to see what would break, tighten the policy over a few weeks, then enforce it.
29% of News & Media peers do this.
