title: What is the correct use of schema.org SiteNavigationElement?
body: <p>In SEO terms...</p>
  
  <p>Is it best to put the scheme on the parent containing all the links?</p>
  
  <pre><code>&lt;nav itemscope="itemscope" itemtype="http://www.schema.org/SiteNavigationElement"&gt;
      &lt;a href="#"&gt;Link 1&lt;/a&gt;
      &lt;a href="#"&gt;Link 2&lt;/a&gt;
      &lt;a href="#"&gt;Link 3&lt;/a&gt;
  &lt;/nav&gt;
  </code></pre>
  
  <p>...or should each link be considered as it's own element?</p>
  
  <pre><code>&lt;nav&gt;
      &lt;span itemscope="itemscope" itemtype="http://www.schema.org/SiteNavigationElement"&gt;
          &lt;a itemprop="url" href="#"&gt;
              &lt;span itemprop="name"&gt;Link 1&lt;/span&gt;
          &lt;/a&gt;
      &lt;/span&gt;
      &lt;span itemscope="itemscope" itemtype="http://www.schema.org/SiteNavigationElement"&gt;
          &lt;a itemprop="url" href="#"&gt;
              &lt;span itemprop="name"&gt;Link 2&lt;/span&gt;
          &lt;/a&gt;
      &lt;/span&gt;
      &lt;span itemscope="itemscope" itemtype="http://www.schema.org/SiteNavigationElement"&gt;
          &lt;a itemprop="url" href="#"&gt;
              &lt;span itemprop="name"&gt;Link 3&lt;/span&gt;
          &lt;/a&gt;
      &lt;/span&gt;
  &lt;/nav&gt;
  </code></pre>
