Image SEO Audit Tool

Signals checked

• Missing, empty, suspicious, duplicate, and overly long alt text values.
• Missing width and height attributes that can cause layout instability.
• Filename heuristics, modern format usage, loading strategy, and srcset coverage.

Crawl risks surfaced

• Flags image assets that appear to load only after JavaScript rendering.
• Calls out weak Open Graph image coverage and preview-image gaps.
• Keeps issue flags exportable at the per-image row level.

Summary

• Total images, alt coverage, empty alt count, suspicious alt count, and lazy-loaded share.
• Separate SEO, accessibility, and performance-related image scores.
• Fast recommendation strip for the highest-value fixes.

Per-image detail

• Preview, source URL, resolved URL, alt, dimensions, format, size bytes, and issue flags.
• Inline issue grouping for missing alt, poor filenames, missing attrs, and heavy assets.
• Structured export designed for handoff to SEO, content, or frontend teams.

Does the audit treat decorative images differently?

Yes. Decorative images can keep an empty alt when the surrounding context makes that intent clear, while content images without useful alt text are flagged.

Why are filename heuristics part of the score?

The filename is not the main signal, but descriptive asset names still help workflow quality, media management, and image-search context.

Can the audit detect JS-rendered images?

The tool is designed to flag likely rendering-only assets so you can decide when a browser-rendered crawl is needed.
