Priority fixes for thanhnien.vn
Ordered by impact and by how common each practice is among peers.
Priority 1 · Enable
Mobile viewport configured
Observed: The homepage had no viewport meta tag, so phones may render it zoomed out.
Why it matters: Without it, phones render the page at desktop width and shrink it, which makes text tiny and hard to use.
What to do: Add <meta name="viewport" content="width=device-width, initial-scale=1"> and check the layout on small screens.
98% 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 · Accelerate
Modern image formats in use
Observed: The homepage had 60 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.
44% of News & Media peers do this.
Guide: AVIF, WebP, JPEG, and PNG: Choose the Right Image Format
Priority 3 · Harden
DMARC policy enforces quarantine or reject
Observed: No DMARC record was found at _dmarc.thanhnien.vn.
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 4 · Harden
Certificate lifetime of 100 days or less
Observed: The certificate from GlobalSign nv-sa had a 199-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.
