What the checker reads
01 / Missing alt
Missing alt attributes.
Images with no alt attribute at all — invisible to screen readers and skipped by image search.
02 / Decorative
Decorative vs described.
We tell apart intentional alt="" decoration from images that simply forgot their alt text.
03 / Too long
Alt text length.
Alt text over 125 characters gets truncated by screen readers and reads as keyword stuffing.
04 / CLS risk
Missing width & height.
Unsized images reserve no space in the layout, causing Cumulative Layout Shift as they load.
05 / Table
Every image, listed.
Src, alt value and status for up to 100 images on the page — no guessing which ones need fixing.
06 / Score
One accessibility score.
Alt coverage and layout-shift risk weighted into a single 0–100 image-accessibility score.
