10% of these page views were in-app (soft) navigations. Those report INP and CLS, but browsers only measure LCP, FCP and TTFB on full page loads, so those three cover fewer page views.
What to fix first
Slow page loads cost you engagement
Comparing like with like (the same page type), page views whose main content took over 4 s got 57% less engaged time and 67% fewer clicks than ones that loaded in under 2.5 s. Based on 43 slow page views across 4 page types.

Mobile visitors get a much slower INP
p75 INP is 281 ms on mobile against 143 ms on desktop. Mobile is 49% 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.

This element makes the page jump as it loads
ul.product-grid
p75 CLS is 0.14 on the 57 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.

Taps and clicks on this element respond slowly
button.add-to-cart
p75 INP is 213 ms over 56 page views, mostly on /c/headsets/. 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.

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.
| LCP | Page views | Clicks per view | Engaged time | Avg scroll |

| Good | 525 | 1.67 | 33.4 s | 56% |
| Needs improvement | 51 | 0.88 | 22.1 s | 57% |
