Happy page views

11% 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
INP got 19% worse than the previous 24h
p75 INP is now 203 ms. The Vitals tab shows when it changed and which pages it changed on.

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 | 59 | 1.63 | 42.3 s | 63% |
| Needs improvement | 5 | 0.80 | 30.8 s | 54% |
