What to fix first
Slow page loads cost you engagement

/search/ pages are slow to show their main content
p75 LCP is 2.51 s over 1100 full page loads; 9% took over 4 s. Most of the time goes on waiting for the server.
Try: Most of the time passes before the HTML arrives: cache pages at the edge/CDN or speed up the server.

Mobile visitors get a much slower INP
p75 INP is 287 ms on mobile against 134 ms on desktop. Mobile is 47% of your page views.
Try: Test on a real mid-range phone or with CPU throttling: big images, heavy JavaScript and third-party scripts cost far more there.

Tablet visitors get a much slower LCP
p75 LCP is 2.92 s on tablet against 2.03 s on desktop. Tablet is 14% of your page views.
Try: Test on a real mid-range phone or with CPU throttling: big images, heavy JavaScript and third-party scripts cost far more there.

#onetrust-accept-btn-handler
p75 INP is 219 ms over 175 page views, mostly on /search/. Most of the time goes on running the event handler.

ul.product-grid
p75 CLS is 0.11 on the 98 page views where it shifted, mostly on /search/.
