Are automated accessibility tools sufficient?
In short and in plain language
No. Testing tools are important, but they are not enough. They find technical faults, such as missing image text or weak contrast.
They cannot tell if a text makes sense. Keyboard use also needs its own check.
That is why we also assess each rule one by one for your site.
No. Automated testing is an important building block, but not a complete proof. Not all WCAG conformance failures can be detected automatically (WebAIM Million 2026). Tools like axe-core or Lighthouse reliably find technical defects like missing alt attributes or insufficient contrast, but cannot judge meaning and context.
Whether an alt text is meaningful, whether a screen reader's reading order stays logical, whether error messages are understandable, or whether a complex widget is keyboard operable, can only be settled by assessing each criterion and operating the page without a mouse.
That is why our WCAG audit combines measurement with the assessment of every criterion and checks of keyboard operation and screen reader output. Only this mix gives a robust picture of the conformance status.
