Automated and manual

You need a combination of automated and manual testing to check accessibility on certain digital assets because automated testing will only catch 30% of accessibility issues. Automated tools can’t test pages that require a login or VPN, so you need to manually test those pages. There aren’t automated testing tools for videos, so they need to be manually checked, too.

• Automated testing: Checker tools like Siteimprove and WAVE.
• Manual testing: Humans perform the checks and typically find more issues than automated testing.

Check out Siteimprove's Accessibility 101 webinars (MyAccess login required) for an introduction to combining automated and manual testing.
