What WCAG level do you audit against?

We typically audit against <strong>WCAG 2.1 Level AA</strong>, which meets most enterprise, legal, and regulatory requirements. Level AAA criteria can be reviewed selectively when required.

How do you approach accessibility audits?

What’s your ARIA usage policy?

Which screen readers do you test with?

How do you measure Core Web Vitals?

Lab vs. field data — which matters more?

What are acceptable performance budgets?

What’s your approach to rolling out fixes?

How often should accessibility compliance be re-verified?

Do you support ongoing monitoring and governance?
