Performance playbook for Next.js launches

Checklists we use for speed, SEO, and analytics before any site goes live.

Ship lean bundles

We aggressively tree-shake icons, lazy-load non-critical blocks, and avoid client components where server components suffice.

Fonts are preloaded with fallbacks to prevent layout shift, and images use next/image with proper sizes.

SEO and analytics are defaults

Metadata is set per page, sitemaps are auto-generated, and robots.txt matches your launch plan.

Analytics is event-based, not pageview-only. We track CTA clicks, form starts, and submissions.

Resilience checks

We run synthetic tests for uptime and measure TTFB from multiple regions to keep the experience GEO-friendly.

Need the playbook? We can apply it to your existing build without a full rewrite.
