A viral video can attract millions of views and for those that get videos to go viral it is often a case of good luck, good timing and having the right people see it. If you want to try your luck:
Post the video on Facebook, Tweet it and throw it up on social bookmarking sites like Reddit. In addition add it to other video sharing sites like Vimeo and DailyMotion and add a good viral video title. The goal is to get eyeballs on your video, get people to share it and find bloggers to write about it. Keep in mind that daily there are thousands of videos uploaded and high competition. If your video isnt good it wont go viral. Good Luck.
