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 52ms (99% good INP, 76% good CLS), compared with a 48ms median INP (99% good INP, 79% good CLS) on the 153,590 sites (72.3%) 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, 72.3% load without a blocking cookie wall (99% good INP, 48ms median) and 27.7% present one (99% good INP, 52ms median).
