This plugin improves your website page load speed substantially by replacing embedded YouTube videos, or YouTube links with a clickable preview image. The image is the original thumbnail from YouTube and features the play button, so users can click to play video and at that moment all necessary JavaScript will be loaded. It increases your website page load speed, especially on the sites with multiple YT video embeds
