title: How do you Defer Parsing of JavaScript for YouTube video on a WordPress site?
body: <p>I just today realized that of my 1.2 MB site (per GTMetrix), 550k of it is a YouTube video.</p>
  
  <p>My web site is a WordPress site, and the current video loads in an iframe.</p>
  
  <p>I want my site to load faster... And not sure how to proceed. If I can make the YouTube video not load until clicked, and just have a thumbnail there instead, it seems like that would be the right play?</p>
