Happy page views

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
/articles/* pages are slow to show their main content
p75 LCP is 4.71 s over 21 full page loads; 33% took over 4 s. Most of the time goes on the image starting to load late.
Try: The browser finds the LCP image late: don't lazy-load it, give it fetchpriority="high", and make it discoverable in the HTML (or preload it).

Slow page loads cost you engagement
Page views whose main content took over 4 s got 74% less engaged time and 83% fewer clicks than ones that loaded in under 2.5 s (10 slow vs 20 fast). This mixes all pages; filter to one path pattern to check it holds within a page type.

Key presses in this element respond slowly
#search_input
p75 INP is 373 ms over 3 page views, mostly on /c/software/. 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.

Taps and clicks on this element respond slowly
nav.toc > a.toc-link
p75 INP is 318 ms over 3 page views, mostly on /search/. 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.

This element makes the page jump as it loads
ul.product-grid
p75 CLS is 0.13 on the 3 page views where it shifted, mostly on /articles/109/.
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.

Based on 35 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 | 20 | 1.75 | 49.9 s | 53% |
| Needs improvement | 5 | 1.20 | 15.7 s | 61% |
