Ecommerce Image Optimization Checklist (2026)
Ecommerce SEO performance is heavily image-bound. Product grids, galleries, and hero banners can quickly destroy LCP and conversion. Use this checklist to systematize your optimization process.
Checklist
- Convert high-traffic product images to WebP or AVIF fallback sets
- Set explicit width/height to prevent CLS
- Compress hero and first-grid images more aggressively
- Lazy load below-the-fold gallery assets
- Write descriptive alt text with product modifiers
- Use meaningful file names before upload
- Create separate mobile image variants for key templates
- Audit category pages for oversized decorative banners
- Track LCP on top revenue templates weekly
- Recompress legacy catalog uploads quarterly
