Cape Diablo page as we captured it
Captured live from the storefront, scored from the outside, the way a customer sees it.
57

Average

out of 100

Cape Diablo has a clean, well-structured product page with solid above-the-fold clarity and a compelling promotional offer, but the page is critically undermined by a PSI mobile score of 27 — an 18-second LCP will bleed the majority of cold mobile traffic before the page even loads. Social proof is thin relative to the brand's claimed 700k+ customers, with no photo reviews or press mentions visible. Fixing mobile performance is the single highest-leverage action available.

Top Finding

PSI mobile score is 27/100. LCP of 17.6s and TBT of 3,900ms are catastrophic — a first-time cold visitor on mobile will stare at a blank or partially loaded page for nearly 18 seconds before the hero image fully renders. FCP at 4.8s means even the first paint is painfully slow.
