How many live stores have broken tracking.
500 stores scanned in September 2026, sampled at random from certificate transparency logs. Method and exclusions stated in full.
Shopify
6.4%
14 of 219 observed stores had a tag loading and staying silent on at least one page type.
WooCommerce
11.3%
25 of 222 observed stores had a tag loading and staying silent on at least one page type.
Fifty-nine stores were excluded because we could not observe them: 38 served a challenge page, 14 had a consent banner we could not resolve, 7 timed out. Excluding them raises the headline rate. Including them would be wrong.
