Why the Accept button is often the slowest interaction on the page

When a cookie wall blocks the page on first visit, the visitor's very first tap happens on the consent button. Many Consent Management Platforms (CMPs) synchronously update storage, remove DOM overlays, and initialize Google Tag Manager and marketing pixels inside that click handler. Across 58,718 sites (27.7%) with a cookie wall, median INP rises to 91ms (96% good INP, 87% good CLS), compared with a 85ms median INP (94% good INP, 88% good CLS) on the 153,590 sites (72.3%) without one.
