## WHAT WAS IMPLEMENTED
|
||||||
|
|
||||||
|
### Phase 5: Content Optimization (10 checks)
|
||||||
|
|
||||||
|
1. **analyze_unoptimized_images()** - Detects large unoptimized images (>500KB)
|
||||||
|
- Fix: Optimize with ImageMagick or plugins
|
||||||
|
- Impact: 30-50% file size reduction
|
||||||
|
|
||||||
|
2. **analyze_webp_conversion()** - Checks for WebP format implementation
|
||||||
|
- Fix: Use Imagify or ShortPixel
|
||||||
|
- Impact: 30-50% smaller files for modern browsers
|
||||||
|
|
||||||
|
3. **analyze_large_assets()** - Finds large unminified CSS/JS files (>100KB)
|
||||||
|
- Fix: Minify with W3 Total Cache or WP Optimize
|
||||||
|

|
||||||
|
|
||||||
|
