G136: Providing a link at the beginning of the nonconforming content that points to an alternate version that does meet WCAG 2.0 at the level claimed


Primary content does not conform to WCAG but alternate versions exist that do conform to WCAG. This technique can only be used if a technology makes it possible to create an accessible link to an alternate version.

This technique relates to:


The objective of this technique is to enable users to access alternate content that does conform to WCAG if the primary content, or the default content that users access from a particular URI, does not conform. The alternate page may make some design or functionality compromises in order to conform but should provide the same content that is available in the primary content.

Placing a WCAG conforming link to alternate content at the top of the page allows users to find the link quickly and move to the alternate version. Each page needs a link to the WCAG conforming version of that page, to ensure users can always find it regardless of where they enter the site.




  1. Identify a page that does not conform to WCAG at conformance Level 1.

  2. Determine if the page contains a link to an alternate version of the page.

  3. Determine if the alternate version conforms to WCAG at conformance Level 1.
