I just created an account at TrafficGeyser.com. It cost me $147 for 1 month subscription and I am allowed to upload 500 videos. Each Video will be submitted to 25+ YouTube like websites. Whats the catch? They say that when lot of such videos are posted in different sites, Google sees that as an important video and brings up in the top 10 SERPs for that keyword. I tried some low competition keywords (having results less than 10k when searched with quotes) and found that it works! I have not got any significant traffic or sales yet, but yes I hope that this thing is wonderful and can be used as a white hat traffic driving method.
