When embedding videos from YouTube, the YouTube player will show related videos any time the video is paused or when it completes.
By default, YouTube itself picks these videos, which means you may very well see a competitor's videos after showing your own.
Not ideal.
If you add ?rel=0 to the Youtube URLs, Google will still show related videos, but it will restrict them to;
This means that if you add the video to a playlist by itself, then no related videos will appear because Google can't find any to display. This is labor intensive to setup for a lot of videos, but it's an easy hack to implement.
Uses video overlays during the pause and completion states to mask the related videos. In the future we may expand these panels to allow for branding and CTAs.

Another means is to use a 3rd party player like Plyr.io, which can play video from YouTube and Vimeo as well. It's free, customizable and styleable.
