Image SEO Checklist (12 Steps)

TinyForge Blog · Image optimization guides

1. Descriptive file names — red-running-shoes.webp not IMG_4821.jpg.
2. Alt text — describe the image for users and crawlers. Include keywords naturally.
3. Compress — smaller images load faster; speed is a ranking factor.
4. Right format — WebP/AVIF for photos.
5. Responsive images — use srcset + sizes.
6. Lazy loading — loading="lazy" below the fold.
7. Dimensions — set width/height to avoid CLS.
8. Captions — optional but help context.
9. Image sitemap — include images in your XML sitemap.
10. Structured data — ImageObject / Product images.
11. CDN + caching — serve from edge, long cache headers.
12. Contextual placement — place images near relevant text.

Run your images through TinyForge to handle steps 3 and 4 in seconds.
