I'm embedding YouTube videos in a widget (http://www.betterdonatebutton.com) to help non-profits raise money. Unfortunately, some of them are not technically inclined enough to turn off ads that display over their videos.
How do I embed a YouTube video and specify that I prefer no ads to be displayed?
?rel=0
at the end of the src in the iframe. For example:src="https://www.youtube-nocookie.com/embed/hello8675309?rel=0"
