How to Make Your Site Faster and Sell More

Speed isn't a "nice to have" — it's revenue. If pages feel instant, people browse more, trust more, and buy more. If they lag, they bounce. The upside: a few practical fixes can move your conversion curve quickly.
Why it matters (beyond "tech")
- More sales: Faster pages reduce drop-off and lift conversion.
- Better first impressions: A quick site feels premium and trustworthy.
- SEO lift: Google surfaces faster, stable pages more often.
Quick wins: fix these first
Load what matters first:
- Hero eager, the rest lazy. Show the banner and key visuals immediately; lazy-load images and videos below the fold.
- Preload hero + fonts. Fetch your main hero image and primary web fonts early to avoid "unstyled text" and late banners.
Ship fewer, smaller files:
- Minify & bundle. Compress CSS/JS/HTML and reduce the number of files the browser must fetch.
- Defer non-essentials. Load analytics, chat, and widgets after the page is visible.
Use a CDN + caching:
- Serve assets from a CDN close to each visitor and turn on browser caching so repeat views feel instant.
Modern images:
- Convert to WebP/AVIF, send the right size per device, and lazy-load galleries.
Clean, lean styling:
- Remove unused CSS. Prefer Tailwind (utility-first) or purge tools instead of shipping large, unused Sass bundles.
Smarter rendering:
- Use SSR/SSG (e.g., Next.js) so pages arrive pre-rendered; users see content immediately (no spinner).
What good looks like
- Hero image and headline appear within ~1–2 seconds on mobile.
- Product and category pages don't jitter (stable layout).
- Key flows (home → PLP → PDP → cart → checkout) feel continuous with no heavy pauses.
- Core Web Vitals and Lighthouse in the 90s on your revenue pages.
Make it a habit
Treat speed like SEO: bake checks into your releases, especially after adding apps, tags, or new media. Re-run audits on home, category, product, and checkout pages.
