Alt-text quality
Beyond present-vs-missing, each unique image's alt text is classified for quality. Filenames, redundant phrasing ("image of…"), and too-short or too-long values are technically present but unhelpful — the cases a human should rewrite. Decorative and "looks good" are not problems.

What it means
Missing alt
141
2%
No alt attribute — a screen reader may announce the filename.
Filename as alt
1
0%
The alt text looks like a filename (e.g. hero_1234.jpg), not a description.
Redundant / meaningless
138
2%
Phrases like "image of…" or bare values like "photo" add nothing.
Too short
8
0%
A single character or word unlikely to convey the image's meaning.
Too long
405
7%
So long it probably belongs in a caption or a separate description.
Looks good
4386
73%
Present, plausible, no red flags (still worth a human spot-check).
Decorative
918
15%
alt="" or aria-hidden — intentionally not announced. Not a problem.
