For all the people that are saying this method is dead: No method ever dies, you just have to adjust it according to the current climate. So, if there are people with just surveys, what you do is set up your own fake "video streaming site", and just embed the videos. You obviously still direct traffic to your main site, and when people click on the other fake site you made, they can watch the video. What you do for monetising is 30 minutes or so down the film, you bring up the survey. By this point, people would not want to flip to another site and would just fill it out. I know this seems harder, but I guarantee you people will be stealing your fake "video streaming site" as a way to watch for their own site, so you'd get traffic like that as well.
Another way you could do it is if you upload the videos to megavideo or w/e yourself, some of these video streaming sites actually pay you for uploading and getting views, so that's another way for some earnings.
You could also try and get their emails i.e. with a username system, and then you can attempt some email marketing.
There are tonnes of ways to twist the basis of this method, you just need to be able to think outside the box. Now please don't go spamming the methods I just wrote, instead, try and think of twists of the twists that I wrote.
