Epilogue: The Numbers After 6 Months
After applying everything:
Before
- Average page size: 2.8MB
- Image percentage: 82%
- LCP: 3.4s
- Mobile Lighthouse: 62
After
- Average page size: 420KB (85% reduction)
- Image percentage: 48%
- LCP: 1.2s (64% improvement)
- Mobile Lighthouse: 94
User feedback changed. "Pages load faster now" comments appeared. Nobody complained before, but improvements brought praise.
Image optimization is respecting users. Users on 3G, with data limits, on slow devices. Not sending them unnecessary megabytes. That was it.
