Baseline Measurement
- Run PageSpeed Insights on mobile and desktop
- Run GTmetrix with a simulated slow connection
- Check Core Web Vitals in Google Search Console
- Record current load times for tracking
Image Audit
- Check largest image file sizes
- Verify all images use WebP or optimized JPEG/PNG
- Check lazy loading is implemented
- Verify explicit width/height on all images
App Audit
- List all installed apps
- Review app performance impact
- Remove unused or replaceable apps
Theme Audit
- Check if theme is the latest version
- Remove unused theme sections and templates
- Minify CSS and JavaScript
- Limit custom fonts to one or two
Technical Audit
- Check server response time
- Verify CDN usage
- Review third-party script loading
- Check for render-blocking resources
Run this audit monthly. Fix the biggest issues first — image optimization delivers the fastest wins.
