Google also cares about site speed for search criteria.

5. Copy the HTML code and Place it wherever you want the video to appear on your page.

6. Copy the JavaScript code and paste it on your page once, ideally right before the closing </body> tag.

Note: In case of multiple videos, you have to put HTML codes where you want to display videos, but Javascript code must be included once.

7. Open your page in browser, play the video and enjoy it. Also, it is responsive means mobile/tablet friendly.

How it works:

Instead of loading the full YouTube video player, It displays a thumbnail of YouTube video with play button by default. Thus, there is no heavy loading and no additional HTTP request. It makes the page faster. YouTube video player is loaded when user clicks on play button only.


Here is comparison of regular and optimized YouTube embed.

    1. Did you use locale file in the browser? Because this script worked for me when I put it on my server host.

  1. Simple & amazing. Exactly what I was looking for one of the sites.
    Really appreciate it & I’m grateful for saving my day quickly.
    Best wishes for your endeavors
    Thanks a ton.

  2. This is amazing, thank you so much! There seems to be a small issue on mobile devices. After clicking the play button, the youtube video loads but does not automatically play. The user has to click on the youtube play button. This requires the user to click 2 times to make the video play. Is there a workaround for this? Much appreciated!

  3. you made my day!! My page was too slow and now this will increase speed. Thanks!
    BTW: if anyone is using PrestaShop or Thirty bees CMS, the script creates an error when introducing it in the body (no idea why) but you can solve the problem just using the header instead!! (route: theme/yourtheme/header.tpl)

  4. Thanks for the awesome tool @TechBrij. I have a question for you please.

    We wanted to display the video as a html pop up. Pop up window opens when a user clicked on a page link, and the YouTube video is embedded in the pop up. Problem is once the pop up is closed video start to play from the beginning in background. Visitor can hear the audio, but no video.

    Do you have a fix for this?

    This technique helped to increase our website speed by over 2 seconds by the way!
