Description
This rule determines if a given href on <a> element is pointing to an external URL and marks for manual verification when the destination URL pointing to a different location than the current page.
Examples of correct code for this rule:
<p>Find the documentation <a href="product-swedish.html" hreflang="sv">about product</a>.</p>How to fix it
Links that pointing to a location in a different language than origin should have an attribute hreflang and specify the language code.
Additionally you can use CSS to display link destination language.
a[hreflang]:after {
content: " [" attr(hreflang) "]";
}Note: don’t use flags to indicate languages! Flags represent countries, not languages.
