title: What does Interstitial timeout mean in admob?
body: <p>When I create an Interstitial ad unit in the Admob page, it asks to input an <code>Interstitial timeout</code>: </p>
  
  <blockquote>
    <p>Determine how long to display the interstitial ad. Valid range is 3 to 10 seconds and must be a whole number.</p>
  </blockquote>
  
  <p>But as far as I know Interstitial ads only close when we touch the close button or when we press the back button on Android phone right? So what is it? </p>
