Accessibility
Screen readers support a large number of languages, for each of which they have a library of sounds that allow the words to be pronounced correctly. If a web page indicates which language content should be read, screen readers are able to switch between the various libraries.
A valid BCP 47 language for the <html> element must be indicated in order to be sure that the page's content pronunciation is correct.
If the <html> element of a page has no valid value for the lang attribute, SeoChecker will notify it:
It's important to adopt a valid language code for the <html> element's lang attribute.
For instance:
<html lang=”en”>
