Happy page views

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 55% less engaged time and 81% fewer clicks than ones that loaded in under 2.5 s. Based on 638 slow page views across 5 page types.

Tablet visitors get a much slower INP
p75 INP is 273 ms on tablet against 155 ms on desktop. Tablet is 12% 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 217 ms over 1699 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.

#onetrust-banner-sdk
p75 CLS is 0.11 on the 1000 page views where it shifted, mostly on /search/.
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.
| LCP | Page views | Clicks per view | Engaged time | Avg scroll |
