title: Error - Asynchronous adsense code in HTML
body: <p>I'm a blogger and I monetize my blog with adsense. While coding or in fact adding asynchronous code inside <code>&lt;head&gt;&lt;/head&gt;</code>tag of my blog it appears that I have to add it like this:</p>
  
  <pre><code> &lt;script async="async" src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>instead of like this:</p>
  
  <pre><code>&lt;script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>Otherwise it will show me an error. Can anyone explain why? Do you know if I'm allowed to add this (according to adsense)?</p>
