title: HTML5 semantic tag usage, will search engines respect large wrapping?
body: <p>I was planning to use the <code>&lt;nav&gt;</code> tag for a few things, however, the following occurred to me.</p>
  
  <p>Take the following markup for example:</p>
  
  <pre><code>&lt;nav id="sidebar"&gt;
  
  &lt;div class="links"&gt;
  &lt;a href="/"&gt;&lt;/a&gt;
  &lt;a href="/"&gt;&lt;/a&gt;
  &lt;a href="/"&gt;&lt;/a&gt;
  &lt;/div&gt;
  
  
  &lt;div class="links"&gt;
  &lt;a href="/"&gt;&lt;/a&gt;
  &lt;a href="/"&gt;&lt;/a&gt;
  &lt;/div&gt;
  
  
  &lt;div class="links"&gt;
  &lt;a href="/"&gt;&lt;/a&gt;
  &lt;/div&gt;
  
  &lt;div class="statement"&gt;
  random content here, unrelated to navigation
  &lt;/div&gt;
  
  &lt;div class="randomstuff"&gt;
  unrelated to navigation, but still here
  &lt;/div&gt;
  
  &lt;/nav&gt;
  </code></pre>
  
  <p>Will search engines respect this sort of usage of semantic tags? By that I mean, "ignore" or lower the priority on all content that's wrapped with a nav tag(even divs and such), even if not directly, or even necessarily all navigational content.</p>
  
  <p>Same question for <code>header</code> and <code>footer</code> tags with <code>div</code>s inside.</p>
  
  <p>Thank you in advance for any assistance.</p>
