I've learnt that some experienced IMs used to effectively promote CPA offers and make quite considerable income with quick videos (animoto style). And what's more - those videos submitted to youtube etc. keep making them money for a long, long time. However, that info might be outdated.
So my question to seasoned CPA marketers - do you find this method of traffic generation still effective these days and if you do - what share (in %) of your other traffic generation methods for CPA this method occupies?
