Happy page views
63%
12% unhappy · 75 rated
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
Taps and clicks on this element respond slowly
button.add-to-cart
p75 INP is 625 ms over 9 page views, mostly on /articles/7/. 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.

CLS got 46% worse than the previous 7d

This element makes the page jump as it loads
div.ad-slot
p75 CLS is 0.10 on the 7 page views where it shifted, mostly on /articles/7/.
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 75 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 | 61 | 1.95 | 43.4 s | 54% |
| Needs improvement | 10 | 0.50 | 28.3 s | 69% |
