Cookie count on Wix sites
<0.1% of audited sites (2) set zero cookies on initial load and pass LCP at 100% (0.9s median), whereas the 4.3% setting 6 or more cookies pass at 87% (1.4s median).
57.7% of Wix sites use 3 to 5 cookies cookie count, and 95% of those sites have a good LCP, against 94% of all Wix sites.
LCP pass rate
Sites with 3 to 5 cookies cookie count have a good LCP most often: 95%, against 94% of all Wix sites. Sites with 6 or more cookies cookies have it least often, at 87%.
Cookie count usage
3 to 5 cookies is the most used: 57.7% of Wix sites.
The four LCP phases
Across the four LCP sub-parts in Chrome's field data, the largest gap between 3 to 5 cookies and 6 or more cookies sits in resource load delay: 435 ms median for 3 to 5 cookies against 524 ms for 6 or more cookies. Overall median field LCP is 1.1s for 3 to 5 cookies (TTFB 390 ms, load delay 435 ms, load duration 106 ms, render delay 150 ms) versus 1.4s for 6 or more cookies.
Cookie count per framework
React sets the cookie count to 3 to 5 cookies on 58% of its sites, and 94% of React sites have a good LCP, against 94% of all sites.

Does the framework explain the cookie count difference?
On React, 95% of sites with 3 to 5 cookies cookie count have a good LCP, against 94% of React sites with 1 to 2 cookies. Within React, sites with 3 to 5 cookies and 1 to 2 cookies have a good LCP about equally often.
How cookie proliferation signals CDN bypass and tracker bloat
High cookie counts reflect two compounding problems: origin Set-Cookie headers that force CDNs to bypass full-page HTML caching, and heavy marketing/ad-tech tags firing during page load. Across 2 sites (<0.1%) setting zero cookies, 100% pass field LCP at a 0.9s median, compared with 87% (1.4s median) on the 4.3% (241) setting 6+ cookies.
Understanding cookie count
Avoid setting session or personalization cookies on anonymous landing pages so CDN edge caches can serve full HTML without Set-Cookie bypasses, and gate marketing cookies behind consent interaction. Across all audited sites, <0.1% set zero cookies (100% good LCP, 0.9s median) versus 4.3% setting 6+ cookies (87% good LCP, 1.4s median).
