title: Hreflang tags on both English and German versions of a website?
body: <p>I'm working on a multi-language website, English and German. I'm using the <code>hreflang</code> tags below on the German website.</p>
  
  <pre><code>&lt;link rel="canonical" href="https://www.website.com/de"&gt;
  &lt;link rel="alternate" href="https://www.website.com/en" hreflang="x-default" /&gt;
  &lt;link rel="alternate" href="https://www.website.com/de" hreflang="de" /&gt;
  </code></pre>
  
  <p>Is it necessary to do the same on the English website? Currently the English website isn't using <code>hreflang</code> tags</p>
