Testing & Remediation

How to test: *If your site includes content that is iframed in, you need to ensure that each of those sub-components have also correctly defined the language. How to remediate: For an english site, use the "lang="en-US"" attribute. If you have a different version of your site in other languages, implement the hreflang tag attribute for each alternative language you have.
