What to fix first
Mobile visitors get a much slower INP
p75 INP is 505 ms on mobile against 78 ms on desktop. Mobile is 57% 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.

#onetrust-accept-btn-handler
p75 INP is 573 ms over 11 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
div.ad-slot
p75 CLS is 0.14 on the 7 page views where it shifted, mostly on /search/.
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 83 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 |

| Needs improvement | 8 | 0.88 | 17.5 s | 69% |
