What to fix first
/p/* pages are slow to show their main content
p75 LCP is 5.23 s over 6 full page loads; 67% took over 4 s. Most of the time goes on the image starting to load late.
Try: The browser finds the LCP image late: don't lazy-load it, give it fetchpriority="high", and make it discoverable in the HTML (or preload it).

The server is slow to respond on /p/*
p75 time to first byte is 2.82 s over 6 page loads, so nothing can appear before then. Most of the time goes on waiting for the server.
Try: The server takes long to start sending the page: cache the HTML (at the CDN if you can) or speed up the code and database queries behind it.

Slow page loads cost you engagement
Page views whose main content took over 4 s got 63% less engaged time and 64% fewer clicks than ones that loaded in under 2.5 s (11 slow vs 75 fast). This mixes all pages; filter to one path pattern to check it holds within a page type.

#onetrust-accept-btn-handler
p75 INP is 306 ms over 16 page views, mostly on /. Most of the time goes on running the event handler.
Try: The event handler itself is slow: do less work in it, or yield (scheduler.yield / setTimeout) before the heavy part.

ul.product-grid
p75 CLS is 0.13 on the 14 page views where it shifted, mostly on /.
Try: Reserve its space before it arrives: width and height (or aspect-ratio) on images and embeds, a min-height for content inserted later, and font-display with matched fallback metrics for web fonts.

Does speed cost engagement?
Page views grouped by their own LCP. If slower pages get fewer clicks and less reading, that's the cost of slowness.
