Happy page views

16% 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
LCP got 50% worse than the previous 30d
p75 LCP is now 2.36 s. The Vitals tab shows when it changed and which pages it changed on.

#onetrust-accept-btn-handler
p75 INP is 291 ms over 9 page views, mostly on /articles/3/. 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 0.22 on the 10 page views where it shifted, mostly on /articles/3/.
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 |

| Needs improvement | 6 | 0.83 | 22.3 s | 49% |
