How to fix it
Add a short, literal description to each image's alt attribute. Decorative images should have an empty alt attribute rather than none.
When it is not a problem
Decorative images should carry an empty alt attribute rather than a description, so a template that writes filenames into alt text is worse than one that leaves it blank.
How Rankelle handles it
- SeverityWarning. It costs traffic or clarity without stopping anything, which is where most real work lives.
- DetectionDetected on a single page while crawling it, then grouped with the other pages under the same URL pattern.
- GroupingEvery page with this finding under the same URL pattern becomes one cause, with a confidence taken from how much of the pattern is affected. 400 of 400 is a template; 6 of 14 is phrased as a question.
- LandingThe affected URLs stay under cheap watch. When this finding is gone from all of them, the fix is marked landed without anyone reporting the deploy.
- VerdictAt landing, comparable untouched URLs are frozen as a control set. Twenty-eight days later the two are compared, and the fix can come back as having done nothing.
