Happy page views
53%
13% unhappy · 30 rated
23% 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 17% worse than the previous 30d
p75 INP is now 246 ms. The Vitals tab shows when it changed and which pages it changed on.
INP over time →
This element makes the page jump as it loads
div.ad-slot
p75 CLS is 0.20 on the 3 page views where it shifted, mostly on /articles/9/.
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 →
Key presses in this element respond slowly
#search_input
p75 INP is 467 ms over 4 page views, mostly on /articles/9/. 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 30 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 | 26 | 1.81 | 38.6 s | 61% |
| Needs improvement | 2 | 1.50 | 27.8 s | 79% |
