What it is
Weight, mobile, accessibility, SEO — where the money leaks. One signal is not a verdict. The score is the whole weighted set, not any single line of it.
How it is weighted
12 points is mid-weight: real evidence, not a smoking gun. On its own it moves the number a few points.
What to do about it
Give every image a real alt (empty alt if decorative), every icon-only button an accessible name, and every interactive element a keyboard path and a visible focus ring. Use a button, not a div with onclick.
Where it fires
Of the homepages we scan as worked examples, this signal fired on 2:
- tailwindcss.com 75/100 — 2 images with no alt, 1 icon-only buttons with no accessible name. Adding these requires knowing why they matter.
- bbc.com 10/100 — 67 images with no alt. Adding these requires knowing why they matter.
