Average
out of 100
Blueprint Bryan Johnson's Longevity Mix page has a strong structural foundation — clear product naming, a founder-anchored value prop, 722 reviews, a well-designed subscribe-and-save module, and a solid upsell section — but it is being severely undermined by a catastrophic mobile performance score of 17/100 that will cause most cold paid traffic to bounce before the page even loads. Social proof lacks depth (no photo reviews, no press bar), and the absence of lifestyle video is a missed opportunity for a brand whose entire identity is built on Bryan Johnson's personal data and protocol. Fix mobile performance first; everything else is secondary.
Top Finding
PSI mobile score of 17/100 is catastrophic: LCP 18.1s, FCP 8.4s, CLS 0.387, TBT 850ms. A first-time cold visitor on mobile will stare at a blank or partially loaded screen for 8+ seconds before seeing any content. This alone will kill a significant share of paid traffic.
