Happy page views
58%
11% unhappy · 132 rated
13% 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 39% worse than the previous 24h
p75 CLS is now 0.11. The Vitals tab shows when it changed and which pages it changed on.
CLS over time →
This element makes the page jump as it loads
div.ad-slot
p75 CLS is 0.31 on the 19 page views where it shifted, mostly on /c/keyboards/.
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.

ul.product-grid
p75 CLS is 0.26 on the 13 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.

Tablet visitors get a much slower INP
p75 INP is 321 ms on tablet against 157 ms on desktop. Tablet is 15% 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.

Taps and clicks on this element respond slowly
button.add-to-cart
p75 INP is 347 ms over 16 page views, mostly on /c/keyboards/. 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.

header.site-header
p75 CLS is 0.16 on the 22 page views where it shifted, mostly on /c/software/. 1 more element that shifts is in the Vitals tab.

Based on 132 page views. Findings need at least 5 measured page views each, so more show up as traffic grows (try the 30d range).
Trend

|---|---|---|---|---|
| Mobile | 60 | 1.53 s | 200 ms | 0.10 |

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 | 126 | 1.63 | 36.2 s | 61% |
| Needs improvement | 6 | 0.67 | 27.0 s | 55% |
