Happy page views

13% unhappy · 1.1k 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
Slow page loads cost you engagement
Comparing like with like (the same page type), page views whose main content took over 4 s got 53% less engaged time and 74% fewer clicks than ones that loaded in under 2.5 s. Based on 28 slow page views across 1 page type.

This element makes the page jump as it loads
ul.product-grid
p75 CLS is 0.25 on the 109 page views where it shifted, mostly on /c/pc-builds/.
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 →
Tablet visitors get a much slower INP
p75 INP is 264 ms on tablet against 161 ms on desktop. Tablet is 11% 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.

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 |

| Needs improvement | 65 | 0.88 | 23.5 s | 58% |
