Happy page views

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 45% less engaged time and 93% fewer clicks than ones that loaded in under 2.5 s. Based on 16 slow page views across 1 page type.

CLS got 32% worse than the previous 7d
p75 CLS is now 0.05. The Vitals tab shows when it changed and which pages it changed on.

LCP got 17% worse than the previous 7d
p75 LCP is now 2.01 s. The Vitals tab shows when it changed and which pages it changed on.

Tablet visitors get a much slower INP
p75 INP is 275 ms on tablet against 174 ms on desktop. Tablet is 16% 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
header.site-header
p75 CLS is 0.15 on the 24 page views where it shifted, mostly on /articles/1/.
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
div.gallery > button.next
p75 INP is 223 ms over 19 page views, mostly on /articles/1/. 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.

Based on 173 page views. Findings need at least 5 measured page views each, so more show up as traffic grows (try the 30d range).

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 | 146 | 1.83 | 35.9 s | 58% |
| Needs improvement | 11 | 0.73 | 15.7 s | 55% |
