I have two videos ranked on google and YT. Ranked #1 for the keyword. A song. And a game's trailer. Like Assassing's Creed Trailer and See You Again - Wiz Khalifa Lyrics. They pretty famous. I think they have gone viral. Because I am getting thousands of views every hour. I am already monetizing them with YouTube/AdSense. I need ideas on how to make extra money with these videos. Because sooner or later, their monetizing rights will be taken down by YT. So I want to make use of this VIRAL MOMENT. Thank you.
