seo-images.SKILL.mdname: seo-images description: Use when optimizing images for SEO — alt text, filenames, formats, lazy loading, responsive sizing. user-invocable: false related-skills: seo, seo-schema, seo-technical
<objective> Checks image SEO fundamentals: descriptive `alt` text (empty only for decorative images), kebab-case descriptive filenames, modern formats (WebP/AVIF with JPG/PNG fallback), `loading="lazy"` on below-fold images, responsive `srcset`/`sizes`, explicit `width`/`height` to prevent CLS, ImageObject schema, and file-size/quality targets per image role (hero/content/thumbnail). </objective>
Image SEO
Checks
- All `<img>` have descriptive `alt` (empty `alt=""` only for decorative)
- Filenames: kebab-case, descriptive (`red-running-shoes.webp` not `IMG_1234.jpg`)
- Formats: WebP/AVIF with JPG/PNG fallback
- Lazy loading: `loading="lazy"` on below-fold images
- Responsive: `srcset` + `sizes` for different viewports
- Dimensions: `width` + `height` set to prevent CLS
File Optimization Targets
| Type | Format | Max size | Quality | |------|--------|----------|---------| | Hero | AVIF/WebP | 200 KB | 75-80 | | Content | WebP | 100 KB | 75 | | Thumbnail | WebP | 30 KB | 70 |
