title: Schema.org Article Microdata on article page and all links to article
body: <p>I have article pages marked up with schema.org microdata such as the following (simplified):</p>
  
  <pre><code>&lt;div itemscope itemtype="http://schema.org/Article"&gt;
      &lt;div itemprop="name"&gt;My Article Title&lt;/div&gt;
      &lt;div&gt;by &lt;span itemprop="author"&gt;John Doe&lt;/span&gt;&lt;/div&gt;
      &lt;meta itemprop="url" content="/link/to/my-article" /&gt;
      &lt;div itemprop="articleBody"&gt;Article body goes here.&lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I have various pages that link to these article pages, such as archive pages segmented by year and month, tag pages, search results, etc. On all of these pages that have links to articles, should I also add schema.org markup such as this:</p>
  
  <pre><code>&lt;div itemscope itemtype="http://schema.org/Article"&gt;
      &lt;a itemprop="url" href="/link/to/my-article"&gt;&lt;span itemprop="name"&gt;My Article Title&lt;/span&gt;&lt;/a&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Or is that frowned upon and/or penalized by the search engines?</p>
