Priority fixes for businessinsider.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Harden
TLS 1.3 negotiated
Observed: The TLS connection negotiated TLSv1.2.
Why it matters: TLS 1.3 removes legacy cipher suites and completes the handshake in fewer round trips, so it is both safer and faster for new connections.
What to do: Enable TLS 1.3 on your CDN or server. Keep TLS 1.2 available for older clients unless you have checked your audience.
93% of News & Media peers do this. Limit: Certificate and protocol were observed from one vantage point; CDNs can present different certificates by region.
Priority 2 · Accelerate
Modern image formats in use
Observed: The homepage had 154 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.
44% of News & Media peers do this.
Guide: AVIF, WebP, JPEG, and PNG: Choose the Right Image Format
Priority 3 · Accelerate
Offscreen images lazy-loaded
Observed: The homepage had 154 images and none used loading="lazy".
What to do: Add loading="lazy" to images below the fold. Do not lazy-load the main hero image, because that delays the largest visible element.
72% 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 198-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.
