Site speed directly affects SEO, conversions, and ad performance. If your pages feel slow, start with this checklist focused on Core Web Vitals and real-world mobile performance.

1. Optimize Above-the-Fold Images First

Compress hero images, use modern formats, and load exact display sizes. Large unoptimized images are still the most common cause of poor Largest Contentful Paint scores.

2. Delay Non-Critical JavaScript

Defer scripts that are not needed for the initial render, especially analytics plugins, chat widgets, and heavy third-party embeds. This reduces main-thread blocking and improves Interaction to Next Paint.

3. Reduce Layout Shift

Set fixed dimensions for images, videos, and ad placeholders so content does not jump while loading. Stable layouts improve user trust and reduce accidental clicks.

4. Cache Static Assets Aggressively

Use long cache headers for versioned CSS, JS, and image assets, and serve files through a CDN close to your visitors. Proper caching can dramatically speed repeat visits.

5. Monitor Core Web Vitals by Page Type

Track homepage, service pages, and blog templates separately in Search Console and performance tools. Fixing the slowest template usually gives the largest site-wide SEO lift.

Speed optimization is not a one-time project. Treat it as a monthly maintenance task to protect rankings and conversions.
