Automated vs Manual Testing for Accessibility

By Kevin Rydberg

Are there tests for accessibility that can not be performed automatically? What are they?

Siteimprove can not test for all accessibility errors. While it can detect many of them, there are some additional tests that can only be done manually. Manual testing should be an integral part of your digital accessibility process/strategy. Ideally, you should be testing with users.

It's also important to note that these checks are different from our warning or review items.
