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
CLS got 538% worse than the previous 24h
p75 CLS is now 0.05. The Vitals tab shows when it changed and which pages it changed on.
CLS over time →
/articles/* pages are slow to show their main content
p75 LCP is 3.97 s over 13 full page loads; 23% took over 4 s. Most of the time goes on waiting for the server.
Try: Most of the time passes before the HTML arrives: cache pages at the edge/CDN or speed up the server.
LCP by page and element →
This element makes the page jump as it loads
div.ad-slot
p75 CLS is 0.18 on the 5 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.
CLS by element →
Based on 20 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 | 15 | 2.40 | 37.6 s | 54% |
| Needs improvement | 2 | 1.00 | 32.0 s | 77% |
| Poor | 3 | 0.33 | 17.2 s | 42% |
