Happy page views

16% 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 67% fewer clicks than ones that loaded in under 2.5 s. Based on 10 slow page views across 1 page type.

/articles/* pages are slow to show their main content
p75 LCP is 5.59 s over 24 full page loads; 42% 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).
LCP by page and element →
People arriving from search get a slow first page
p75 LCP of the landing page is 8.54 s for 11 search visits, and 36% of them bounced. It's their first impression, and page experience is one of Google's ranking signals.

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.
