Just a little bit of savvyness...
My mate was on youtube and came across a guy who was mad into reviewing gadgets of various kinds. He had around 20,000 subscribers and most of his videos had views in the hundreds of thousands.
Also, none of the gadgets he was reviewing had affiliate links in them - this guy knew nothing about affiliate marketing, he just loved making these vids.
My mate contacted him and offered to give him a couple of hundred dollars if he'd do a review of his product and post it out to his subscribers.
The youtube guy was stoked and totally went for it.
6 months later this one video made my mate well over 50k. That's $50,000 just from sending out one email.
Pretty crazy huh. These extreme results aren't likely to happen too often but it just shows that thinking outside the box is the key to traffic generation!
