title: Unnecessary to add title on ALL links?
body: <p>I know some SEO, but I have to ask:</p>
  
  <p>Is it unnecessary to add title on a link if there is no optimisation for that word or page (for example a link to a "contact page", wich I don't bother to rank high on Google). Or does google some how value that all links have title?</p>
  
  <pre><code>&lt;a href="/contact" title="Unnecessary title"&gt;Click here to contact us&lt;/a&gt;
  &lt;a href="/contact"&gt;Click here to contact us&lt;/a&gt;
  </code></pre>
  
  <p><strong>My thought is:</strong></p>
  
  <p>Only add title when</p>
  
  <p>a) You want to help the page rank on google.</p>
  
  <p>or</p>
  
  <p>b) If you care about the yellow little hover-message.</p>
