Question: Have you ever had anybody ask about how we can get youtube videos from showing related videos after the end of their videos?
Solution:
Yes, I have. We actually recommend this so that your customers stay focused on your brand and don’t get distracted by other videos.
When you are getting the embed code from the video on YouTube.com, there are options below where you copy the code. Make sure that the box for “Show suggested videos when the video finishes” is not checked.
UPDATE: Since this question was asked, I have talked to our developers and this is now a default feature on the mobile sites!
