Understanding web pages better
I was under the assumption that Googlebot already used a headless Chrome to index websites for some time.<p>Google used Chrome to generated page preview pictures (at index-time) to show the search terms (mouse over, but this feature is no more, as it seems). Some websites that shows you the user agent displayed the Chrome user-agent in the preview picture, back then (~2 years ago).<p>it was called <i>Instant Preview</i>: <a href="http://googlesystem.blogspot.co.at/2010/11/google-instant-previews.html" rel="nofollow">http://googlesystem.blogspot.co.at/2010/11/google-instant-pr...</a><p>details: <a href="https://sites.google.com/site/webmasterhelpforum/en/faq-instant-previews" rel="nofollow">https://sites.google.com/site/webmasterhelpforum/en/faq-inst...</a><p>Google removed this useful feature in 04/2013 :(<p><pre><code>  As we’ve streamlined the results page, we’ve had to 
  remove certain features, such as Instant Previews.
