We periodically update accessibility checks to account for changes in regulations and align as closely as possible with W3C standards. The following checks within our existing guidelines were updated on June 14, 2018.
These checks should not be confused with new guidelines for WCAG 2.1.
If you want to read more about Siteimprove’s collaboration with W3C and partners including work on WCAG 2.1 please see “FAQ on WCAG 2.1 - The new standard for Accessibility”.
You may notice a deviation in the number of issues and/or occurrences of issues associated with the checks below.
