Priority fixes for 3ceni.by
Ordered by impact and by how common each practice is among peers.
Priority 1 · Harden
Certificate has more than 14 days left
Observed: The certificate from GlobalSign nv-sa was due to expire on 2026-11-05 (13 days after the check).
Why it matters: An expired certificate makes browsers show a full-page warning. Renewing well ahead of expiry leaves time to fix a failed renewal.
What to do: Automate renewal with ACME (for example Let's Encrypt or your CDN's managed certificates) and add a renewal review to your release calendar so any certificate inside 21 days of expiry gets attention.
>99% of E-Commerce & Marketplaces peers do this. Limit: Certificate and protocol were observed from one vantage point; CDNs can present different certificates by region.
Priority 2 · Accelerate
Static files cached for 30 days or more
Observed: A same-site stylesheet or script was cacheable for 1 days, short of the 30-day benchmark.
What to do: Give versioned (fingerprinted) CSS, JavaScript, fonts and images Cache-Control: public, max-age=31536000, immutable, and change the file name whenever the content changes.
60% of E-Commerce & Marketplaces peers do this.
Priority 3 · 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.
85% of E-Commerce & Marketplaces peers do this.
Priority 4 · Accelerate
No render-blocking scripts in <head>
Observed: The homepage <head> loaded 66 external scripts 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.
44% of E-Commerce & Marketplaces peers do this.
