title: Breadcrumbs on current page
body: <p>I have currently implemented my breadcrumbs like this:</p>
  
  <pre><code>&lt;div itemscope itemtype="http://data-vocabulary.org/Breadcrumb"&gt;
      &lt;a href="HOME URL" itemprop="url"&gt;
          &lt;span itemprop="title"&gt;HOME TITLE&lt;/span&gt;
      &lt;/a&gt; &gt; 
  &lt;/div&gt;
  &lt;div itemscope itemtype="http://data-vocabulary.org/Breadcrumb"&gt;
      &lt;a href="1ST LEVEL URL" itemprop="url"&gt;
          &lt;span itemprop="title"&gt;1ST LEVEL TITLE&lt;/span&gt;
      &lt;/a&gt; &gt; 
  &lt;/div&gt;
  &lt;div itemscope itemtype="http://data-vocabulary.org/Breadcrumb"&gt;
      &lt;span itemprop="title"&gt;CURRENT TITLE&lt;/span&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>As you can see, I haven't specified a url for the current page, which would be redundant. 
  But when I try the <a href="https://developers.google.com/structured-data/testing-tool/" rel="noreferrer">Google testing tool</a>, I get an error saying that the url is missing for the current page breadcrumb.</p>
  
  <p>Given that, I have three options that I can think of.</p>
  
  <p>I specify a url for the current page:</p>
  
  <pre><code>&lt;div itemscope itemtype="http://data-vocabulary.org/Breadcrumb"&gt;
      &lt;a href="HOME URL" itemprop="url"&gt;
          &lt;span itemprop="title"&gt;HOME TITLE&lt;/span&gt;
      &lt;/a&gt; &gt; 
  &lt;/div&gt;
  &lt;div itemscope itemtype="http://data-vocabulary.org/Breadcrumb"&gt;
      &lt;a href="1ST LEVEL URL" itemprop="url"&gt;
          &lt;span itemprop="title"&gt;1ST LEVEL TITLE&lt;/span&gt;
      &lt;/a&gt; &gt; 
  &lt;/div&gt;
  &lt;div itemscope itemtype="http://data-vocabulary.org/Breadcrumb"&gt;
      &lt;a href="CURRENT LEVEL URL" itemprop="url"&gt;
          &lt;span itemprop="title"&gt;CURRENT TITLE&lt;/span&gt;
      &lt;/a&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I just display the current page title without including it in the structured data markings:</p>
  
  <pre><code>&lt;div itemscope itemtype="http://data-vocabulary.org/Breadcrumb"&gt;
      &lt;a href="HOME URL" itemprop="url"&gt;
          &lt;span itemprop="title"&gt;HOME TITLE&lt;/span&gt;
      &lt;/a&gt; &gt; 
  &lt;/div&gt;
  &lt;div itemscope itemtype="http://data-vocabulary.org/Breadcrumb"&gt;
      &lt;a href="1ST LEVEL URL" itemprop="url"&gt;
          &lt;span itemprop="title"&gt;1ST LEVEL TITLE&lt;/span&gt;
      &lt;/a&gt; &gt; 
  &lt;/div&gt;
  &lt;span&gt;CURRENT TITLE&lt;/span&gt;
  </code></pre>
  
  <p>I don't display the current level in the breadcrumbs (I don't want to do that I must say):</p>
  
  <pre><code>&lt;div itemscope itemtype="http://data-vocabulary.org/Breadcrumb"&gt;
      &lt;a href="HOME URL" itemprop="url"&gt;
          &lt;span itemprop="title"&gt;HOME TITLE&lt;/span&gt;
      &lt;/a&gt; &gt; 
  &lt;/div&gt;
  &lt;div itemscope itemtype="http://data-vocabulary.org/Breadcrumb"&gt;
      &lt;a href="1ST LEVEL URL" itemprop="url"&gt;
          &lt;span itemprop="title"&gt;1ST LEVEL TITLE&lt;/span&gt;
      &lt;/a&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>What do you think it's best I should do?</p>
