> 4 WCAG criteria fully tested. 22 different tests
There are 4 WCAG principles with 12-13 guidlines, each having at least one success criteria. There are about 60 success criteria, so 22 different tests are far from 100%. I've also encountered many subjective decisions and screen reader quirks. It's probably much better than fully-automated tools (like pa11y or axe), but it still takes a lot of experience to find and fix all accessibility issues. I suggest lowering the "100%" claim.

Yeah, so I just marked your email address as spam. I never subscribed for any newsletter and there isn't any unsubscribe button either in your mail nor your website. Just stop.
