Guess this could go just about anywhere, but this is what I've started doing with adwords.. Watch the morning news. If you are lucky, they might have a part of the show where they talk about some new item that came to the market. JUMP ON IT I've got it down to the point where as soon as I see the news cast I can get an ad created in less than 5 minutes. By the time I get to my day job, there are already impressions and clicks. I've been able to snap up buy keywords on specific items on the cheap, with either myself or one other competitor. Finding an affiliated company that sells the item is a different subject. Now back to your regularly scheduled program....
the main problem with this is that you are trying to market a product you are not familiar with. Your best bet and most success will come from marketing a product you enjoy yourself. If you really love bicycles, then find bicycle affiliate programs and begin marketing from there. Don't dive into items and product you have no lingo on. What if the news announces a new product, you jump on it, and then it fails market penetration, or the company flops. You will end up losing more money than you expect.
