Core Web Vitals Optimization for eCommerce & D2C — Faster, Better-Converting
Google’s Core Web Vitals directly impact your search rankings, page experience and conversion rate. Slow websites lose traffic, SEO visibility and revenue — especially on mobile.
We optimize CWV for Shopify stores, headless commerce, PWAs, Next.js storefronts and high-performance D2C brands to deliver fast loading, stable layouts and smooth interactions.
USP bullets:
- Improve LCP, CLS, INP & TTFB
- Mobile-first performance optimization
- Shopify & Headless performance engineering
- Image, JS & theme optimization
- Better SEO, lower bounce rate, higher conversions
