If your site has consistently poor Total Blocking Time scores, which approach should you take to improve this metric?

  • Remove all videos from your site that are 1MB or larger
  • Optimize images and use srcset and sizes attributes to provide the browser multiple image options depending on the user’s device
  • Self-host fonts instead of fetching them from a third party
  • Reduce the total amount of JavaScript loaded on your site while also efficiently loading the site’s JavaScript
