title: Google hreflang language confusion: Do I have to add hreflang for the page ITSELF?
body: <p>On <a href="https://support.google.com/webmasters/answer/189077?hl=en" rel="nofollow">Google's <code>hreflang</code> documentation</a>, in the 2-language example, it says:</p>
  
  <blockquote>
    <p>Imagine you have an English language page hosted at
    <a href="http://www.example.com/" rel="nofollow">http://www.example.com/</a>, with a Spanish alternative at
    <a href="http://es.example.com/" rel="nofollow">http://es.example.com/</a>. You can indicate to Google that the Spanish
    URL is the Spanish-language equivalent of the English page in one of
    three ways:  </p>
    
    <ul>
    <li><p><strong>HTML link element in header.</strong> In the HTML <code>&lt;head&gt;</code> section of <a href="http://www.example.com/" rel="nofollow">http://www.example.com/</a>, add a <code>link</code> element pointing to the Spanish
    version of that webpage at <a href="http://es.example.com/" rel="nofollow">http://es.example.com/</a>, like this:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;link rel="alternate" hreflang="es" href="http://es.example.com/" /&gt;
  </code></pre></li>
    </ul>
  </blockquote>
  
  <p>But in its 3-language example, it says:</p>
  
  <blockquote>
    <p>If you have multiple language versions of a URL, each language page
    must identify all language versions, <strong>including itself</strong>.  For
    example, if your site provides content in French, English, and
    Spanish, the Spanish version must include a rel="alternate"
    hreflang="x" link for itself in addition to links to the French and
    English versions. Similarly, the English and French versions must each
    include the same references to the French, English, and Spanish
    versions.</p>
  </blockquote>
  
  <p>The above is an example for a 3-language site. My website consists of only 2 languages - the default/main ENGLISH and THAI. Do I have to add the tag <strong>for the page itself</strong>? Google's documentation is not clear about this point and in its example for 2-language site, it is not mentioned.</p>
  
  <p>For example, this is what I put in <a href="http://janwawa.com/en/contact.php" rel="nofollow">http://janwawa.com/en/contact.php</a></p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;!-- GOOGLE INTERNATIONAL LANGUAGE TARGETING --&gt;
  &lt;link rel="alternate" hreflang="th" href="http://janwawa.com/th/contact.php"&gt;
  &lt;link rel="alternate" hreflang="x-default" href="http://janwawa.com/en/contact.php"&gt;
  &lt;/head&gt;
  </code></pre>
  
  <p>Is the above correct? Or should I use:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;!-- GOOGLE INTERNATIONAL LANGUAGE TARGETING --&gt;
  &lt;link rel="alternate" hreflang="en" href="http://janwawa.com/en/contact.php"&gt;
  &lt;link rel="alternate" hreflang="th" href="http://janwawa.com/th/contact.php"&gt;
  &lt;link rel="alternate" hreflang="x-default" href="http://janwawa.com/en/contact.php"&gt;
  &lt;/head&gt;
  </code></pre>
