Image SEO checks for media-heavy websites and catalog pages
Image SEO becomes meaningful when checks move beyond missing alt text and start looking at patterns across galleries, product grids, and content templates.

Why image SEO is often under-reported
Many checkers still treat image SEO as a binary rule: alt text present or missing. That is too shallow for ecommerce, editorial, and portfolio-style sites where image usage is central to the page experience and search surface.
Signals worth tracking
The strongest image checks look for repeated empty patterns, generic alt text, broken media references, and templates that consistently omit descriptive context for important assets.
- Missing alt text on meaningful assets
- Repeated generic alt text across many pages
- Broken or unresolved image URLs
- Template blocks that insert decorative images without context
Group by page type and asset role
A homepage hero image and a product thumbnail do not carry the same SEO weight. Reports become more useful when they separate primary content images from decorative media and repeated layout assets.
How teams fix it
Most image SEO improvements happen through template changes, media library standards, or feed enrichment. Reporting should connect the issue to those systems so teams can make durable improvements instead of patching one page at a time.
