body: <p>Is there anyway to install an extention without visiting to google app store? 
  For example I want visitors, can install my extention just one clicking a facebook ad or a banner?</p>
  
  <p>Is it possible? </p>
  
  <p>I read some article that mentioning about to verified site ownership to do this. But I want to make advertisement on facebook so I wouldn't be owner of the web page...</p>
  
  <p>Does anyone have information on this subject?</p>
