5 Shopify mistakes kill conversions

Short summary

Shopify stores lose 30-50% of sales to fixable technical issues: bloated hero images slow LCP, excessive apps inject scripts, missing caching wastes server time, absent trust signals kill checkout conversion, and localization gaps lose international revenue. Each issue has a concrete fix: compress images to WebP, audit apps quarterly, use cache blocks, add security badges and return policy, and enable Markets. These optimizations can increase conversion by 20-40%.

• •Hero image optimization (WebP compression) reduces LCP from 3-5s to <1s on mobile
• •Audit installed apps quarterly; each app adds script load and slows checkout
• •Enable Markets for currency/localization; estimated 20-40% international conversion lift
