title: Adsense scripts references - single or multiple copies per page
body: <p>I'm currently using adsense code on the page as it was generated by Adsense->New Ad Unit. </p>
  
  <pre><code>&lt;script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"&gt;&lt;/script&gt;
  &lt;ins class="adsbygoogle"
       style="display:block"
       data-ad-client="ca-pub-XXXXXX"
       data-ad-slot="XXXXX"
       data-ad-format="auto"&gt;
  &lt;/ins&gt;
  &lt;script&gt;
  (adsbygoogle = window.adsbygoogle || []).push({});
  &lt;/script&gt;
  </code></pre>
  
  <p>There are three ad blocks per page, so I'm referencing adsbygoogle.js three times.</p>
  
  <p>I've tried to remove all but the first reference to adsbygoogle.js and it seems to work just fine.</p>
  
  <p>So the question is - is it safe to use just a single reference to Adsense javascript, both in terms of risk of breaking the functionality and violating adsense TOS?</p>
