Make it fast - shippingszn launch readiness

How quickly your pages load and respond. Fast feels professional and confident; slow feels broken and amateur — even if everything technically works.

People bail on slow pages, and they bail fast — most users give up on a site that takes longer than three seconds. Fast sites also rank better in search.

Owner verification required: Performance depends on live assets, hosting cache headers, network waterfalls, and Core Web Vitals. The scanner cannot prove real mobile load speed from checklist content alone.

The Launch Fix Kit keeps scan-specific findings, file and line evidence, AI-builder punch-list tasks, and verification steps tied to the paid report.

Compress and resize images before uploading. Use modern formats (webp, avif). Don't serve a 5MB photo when 200KB looks identical.
Set up caching headers on static stuff (images, fonts, CSS) so returning visitors don't re-download everything.
Run your homepage through https://pagespeed.web.dev — aim for 90+ on mobile.
Avoid loading huge JavaScript bundles. If you're using a framework, lazy-load anything that isn't needed for the first paint.
Use a CDN (Cloudflare's free tier works great) so people far from your server still get fast loads.
