Priority fixes for nmas.com.mx
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
Modern image formats in use
Observed: The homepage had 28 images and none used WebP or AVIF.
Why it matters: WebP and AVIF are typically much smaller than JPEG or PNG at similar quality, and images are often the heaviest part of a page.
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 Next.js: The next/image component serves optimized formats automatically.
44% of News & Media peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.

Priority 2 · Harden
DMARC policy enforces quarantine or reject
Observed: The DMARC policy for nmas.com.mx was p=none, which asks receivers to take no action on failing mail.
What to do: Publish DMARC with p=none and a reporting address first, fix any legitimate senders that fail SPF or DKIM alignment, then move to quarantine and finally reject.
37% of News & Media peers do this.
Priority 3 · Accelerate
No render-blocking scripts in <head>
Observed: The homepage <head> loaded 1 external script without async or defer.
What to do: Add defer to scripts that need the DOM, async to independent ones such as analytics, or move them to the end of the body.
On Next.js: Use the next/script component with an appropriate loading strategy.

Priority 4 · Harden
X-Content-Type-Options: nosniff
Observed: The homepage response did not include X-Content-Type-Options: nosniff.
What to do: Send X-Content-Type-Options: nosniff on all responses and make sure each file is served with the correct Content-Type.
On Next.js: Add it in next.config.js headers().
42% of News & Media peers do this.
