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 1,592 sites (16.6%) with a cookie wall, median INP rises to 95ms (93% good INP, 85% good CLS), compared with a 78ms median INP (96% good INP, 93% good CLS) on the 7,978 sites (83.4%) without one.
Understanding cookie consent walls
If your site requires a consent banner, render it as a fixed overlay (position: fixed) with inlined critical CSS so it cannot shift layout, keep its text concise so it does not hijack LCP, and yield to the main thread between closing the banner and booting third-party analytics tags on click. Across all audited sites, 83.4% load without a blocking cookie wall (96% good INP, 78ms median) and 16.6% present one (93% good INP, 95ms median).
