What share of Shopify sites pass Core Web Vitals compared with other ecommerce platforms?

How do Shopify sites rank on Core Web Vitals against other platforms?

Wix leads the six platforms tracked at 81% of mobile origins passing the Core Web Vitals assessment, with Shopify second at 76%, 339,538 of 445,297 tested origins, then Squarespace at 71%, BigCommerce at 63%, Magento at 45% and WooCommerce at 39%, in HTTP Archive's September 2026 data, computed by Deploi.

Which Core Web Vital separates the platforms most?

Loading speed splits the platforms most. In HTTP Archive's September 2026 mobile data, 88% of Shopify origins pass the loading check (LCP), against 85% for Wix, 84% for BigCommerce, 78% for Squarespace, 58% for Magento and 43% for WooCommerce, computed by Deploi.

How do the platforms compare on responsiveness?

Responsiveness separates the platforms least: each of the six platforms tracked passes INP on at least 84% of the mobile origins rated on it in HTTP Archive's September 2026 data, computed by Deploi. Squarespace and BigCommerce lead at 97%, Wix passes 93%, WooCommerce 91%, Shopify 87% and Magento 84%.

Which platforms keep page layouts stable?

Of the six platforms tracked, Wix passes the layout stability check (CLS) most often, at 98% of tested mobile origins in HTTP Archive's September 2026 data, computed by Deploi. Shopify passes at 92%, Squarespace at 89%, WooCommerce at 89%, BigCommerce at 73% and Magento at 71%.

How many origins sit behind each platform's rate?

The pass rates rest on very different group sizes in HTTP Archive's September 2026 mobile data: 542,541 tested WooCommerce origins, 445,297 Shopify, 177,709 Wix, 89,052 Squarespace, 32,325 Magento and 11,660 BigCommerce. Each rate is good origins over tested origins, computed by Deploi, so the smaller groups carry more uncertainty.

Does moving platforms improve a site's Core Web Vitals?

The data cannot say whether a replatform improves speed. HTTP Archive's September 2026 mobile data show 76% of Shopify origins and 39% of WooCommerce origins passing the Core Web Vitals assessment, but platforms host different kinds of sites, so a pass rate describes the sites on a platform. It does not measure what a platform does to any one site.

How is the pass rate computed?

A pass rate is origins with a good rating divided by origins tested, computed by Deploi from HTTP Archive's Tech Report for September 2026, mobile, worldwide. The overall rate is the Core Web Vitals assessment, which needs good LCP and CLS plus good INP where an origin has INP data. That is why 339,538 Shopify origins pass overall, 76% of 445,297, while 324,684 are rated good on INP.
