“(no written value proposition above the fold — hero is image + "Shop now")”
A cold shopper from a paid ad sees a photo and a button. Nothing tells them why Gymshark leggings out-perform Lululemon or a $20 Amazon pair. The page assumes brand awareness the ad audience may not have.
“Add a one-line hero headline: "Squat-proof, sweat-wicking gym wear — engineered with athletes, worn by 18M+."”
Names the concrete product benefit (squat-proof, sweat-wicking), the differentiator (built with athletes), and a scale proof. Gives cold traffic a written reason to keep scrolling.
