Priority fixes for cartier.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
Static files cached for 30 days or more
Observed: A same-site stylesheet or script was cacheable for 30 days, short of the 30-day benchmark.
Why it matters: Returning visitors and later page views reuse cached files instead of downloading them again.
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.
On Cloudflare: Use Cache Rules to set edge and browser TTLs for static file paths.
60% of E-Commerce & Marketplaces peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.
Priority 2 · Accelerate
Modern image formats in use
Observed: The homepage had 240 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.
47% of E-Commerce & Marketplaces 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 240 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 E-Commerce & Marketplaces peers do this.
Priority 4 · Enable
At most one redirect to the homepage
Observed: The homepage was reached after 2 redirects.
What to do: Point every alternate address (http, www or apex, old paths) straight to the final URL in a single redirect.
98% of E-Commerce & Marketplaces peers do this.
