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.

Alt-text quality across 38 unique image(s).
VerdictImagesShareWhat it means
Redundant / meaningless25%Phrases like "image of…" or bare values like "photo" add nothing.
Too short25%A single character or word unlikely to convey the image's meaning.
Looks good3489%Present, plausible, no red flags (still worth a human spot-check).
