Priority fixes for klook.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
Modern image formats in use
Observed: The homepage had 79 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 Cloudflare: Cloudflare Polish can convert images to WebP.
41% of Travel Bookings & Trip Planning peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.

Priority 2 · Accelerate
No render-blocking scripts in <head>
Observed: The homepage <head> loaded 2 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 Travel Bookings & Trip Planning peers do this.

Priority 3 · Accelerate
Offscreen images lazy-loaded
Observed: The homepage had 79 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.
62% of Travel Bookings & Trip Planning peers do this.
Priority 4 · Accelerate
HTTP/3 advertised
Observed: The homepage did not advertise HTTP/3 through an Alt-Svc header.
What to do: Turn on HTTP/3 at your CDN. Browsers fall back to HTTP/2 automatically, so the risk is low.
On Cloudflare: Enable HTTP/3 (with QUIC) under Speed > Optimization > Protocol Optimization.
33% of Travel Bookings & Trip Planning peers do this.
