12% 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 59% less engaged time and 80% fewer clicks than ones that loaded in under 2.5 s. Based on 88 slow page views across 1 page type.

Mobile visitors get a much slower INP
p75 INP is 263 ms on mobile against 153 ms on desktop. Mobile is 51% 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
div.ad-slot
p75 CLS is 0.10 on the 122 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.

p75 INP is 230 ms over 99 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.

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 | 991 | 1.69 | 33.3 s | 57% |
| Needs improvement | 106 | 0.94 | 24.6 s | 55% |
