Shopify cookie count and the Core Web Vitals
0.1% of audited sites (6) set zero cookies on initial load and pass LCP at 80% (1.6s median), whereas the 58.6% setting 6 or more cookies pass at 95% (1.4s median).
17.5% of Shopify sites use 1 to 2 cookies cookie count, and 98% of those sites have a good LCP, against 96% of all Shopify sites.
LCP pass rate
Sites with 1 to 2 cookies cookie count have a good LCP most often: 98%, against 96% of all Shopify sites. Sites with 6 or more cookies cookies have it least often, at 95%.
Cookie count usage
6 or more cookies is the most used: 58.6% of Shopify sites. 1 to 2 cookies is 17.5% of Shopify sites.
The four LCP phases
Across the four LCP sub-parts in Chrome's field data, the largest gap between 1 to 2 cookies and 6 or more cookies sits in resource load delay: 534 ms median for 1 to 2 cookies against 616 ms for 6 or more cookies. Overall median field LCP is 1.2s for 1 to 2 cookies (TTFB 382 ms, load delay 534 ms, load duration 218 ms, render delay 255 ms) versus 1.4s for 6 or more cookies.
Cookie count per framework
On jQuery, 67% of sites use 6 or more cookies cookie count, and 94% of jQuery sites have a good LCP, against 96% of all sites. On Vue, 65% of sites use 6 or more cookies, and 95% of Vue sites have a good LCP.

Does the framework explain the cookie count difference?
On jQuery, 97% of sites with 1 to 2 cookies cookie count have a good LCP, against 93% of jQuery sites with 6 or more cookies. Within jQuery, sites with 1 to 2 cookies have a good LCP more often. On Vue, 97% of sites with 1 to 2 cookies cookie count have a good LCP, against 94% of Vue sites with 6 or more cookies. Within Vue, sites with 1 to 2 cookies and 6 or more 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 6 sites (0.1%) setting zero cookies, 80% pass field LCP at a 1.6s median, compared with 95% (1.4s median) on the 58.6% (4,831) 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 (80% good LCP, 1.6s median) versus 58.6% setting 6+ cookies (95% good LCP, 1.4s median).
