What to fix first
Slow page loads cost you engagement
Page views whose main content took over 4 s got 58% less engaged time and 83% fewer clicks than ones that loaded in under 2.5 s (14 slow vs 414 fast). This mixes all pages; filter to one path pattern to check it holds within a page type.

This element makes the page jump as it loads
div.ad-slot
p75 CLS is 0.21 on the 50 page views where it shifted, mostly on /.
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.

Taps and clicks on this element respond slowly
nav.toc > a.toc-link
p75 INP is 211 ms over 39 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.

All three Core Web Vitals pass
p75 LCP 1.35 s, INP 149 ms, CLS 0.04: that's Google's "good" for each. Watch "Biggest changes" for regressions.

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 | 414 | 1.65 | 33.4 s | 57% |
| Needs improvement | 21 | 0.76 | 16.1 s | 61% |
