Performance & Core Web Vitals
Speed is conversion. Web Shop Manager builds fitment-driven stores on a modern, headless-capable stack — and we don’t launch one below a 90 PageSpeed score. Fast pages rank better, convert better, and cost less to acquire customers for.
A 90+ launch gate, not a someday goal.
A 90+ PageSpeed score is our launch gate, not an aspiration
Most platforms treat performance as something you chase after launch. We treat it as a gate: a WSM 6.0 store does not go live until it scores in the 90s on mobile. That discipline forces every lever — image handling, fonts, code-splitting, caching, and a fast edge — to be right before a single customer arrives. Performance stays strong as long as a site is not loaded with third-party scripts that break it, and we give clients documentation to add those safely.
- Every WSM 6.0 store launches at a 90+ mobile PageSpeed score
- Built on a modern, headless-capable Next.js stack with incremental static rendering
- Images, fonts, and code tuned for Core Web Vitals out of the box
- Served from a global edge CDN so pages load close to the shopper
Engineered for Core Web Vitals
- Largest Contentful Paint kept under 2.5s with eager-loaded hero images and a fast server response
- Interaction to Next Paint kept responsive by code-splitting and deferring non-critical JavaScript
- Cumulative Layout Shift controlled with reserved image dimensions and size-adjusted fonts
- Right-sized, modern-format images served automatically to every device
Smart rendering and caching
- Incremental Static Regeneration serves cached pages instantly while refreshing them in the background

Performance FAQs
Core Web Vitals are performance signals Google uses to evaluate page experience. Faster LCP, low CLS, and strong INP typically correlate with better usability, higher conversion, and stronger technical SEO signals.
WSM 6.0 uses a Next.js storefront deployed to edge infrastructure. Server rendering and incremental builds reduce time-to-render, and Next.js handles image, font, and code optimization to keep pages fast as catalogs grow.
Performance is a technical SEO factor and also affects engagement. Faster storefronts tend to reduce bounce and improve user experience, which supports organic visibility over time.
Large catalogs can create performance risk when pages are built dynamically on every request. WSM’s storefront uses pre-rendering and incremental regeneration patterns so category and product pages remain fast even as SKU count grows.
Images often drive LCP and layout shift. Next.js image optimization and consistent sizing reduce CLS and improve load performance, especially on mobile.
Typically no. Performance is engineered into the stack with server rendering, edge delivery, and built-in optimization rather than relying on a patchwork of caching plugins.
