Happy page views
48%
11% unhappy · 27 rated
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 38% worse than the previous 24h
p75 INP is now 278 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 0.28 on the 6 page views where it shifted, mostly on /c/mice/.
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 →
Taps and clicks on this element respond slowly
button.add-to-cart
p75 INP is 522 ms over 3 page views, mostly on /c/mice/. 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.

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.
