My guess is that you are sending extremely untargeted traffic. My conversion rate for Amazon is about 5% ... And on some products it's even better. Amazon can definitely convert at high levels. It's all about putting the right products in front of the right people.
Agreed. People always bash the 1-day cookie but it's totally possible and profitable.... Wait, nevermind. It's definitely NOT and nobody should use amazon unless you're shopping.
Strange ... it seems your links are correct. I see your affiliate id. Is the traffic from Search engines? If the origin of the clicks is in some guaranteed hits....forget any serious conversion rate. I have around 800 visitors per day and i am making 80-150 sales / month with science fiction.
It is hard to get conversions on Amazon. I'm a newbie to it and have only got one successful conversion thus far.
I think you niche is too.........unnatural lol! I think you should change your niche to something better but let the UFO site stay live. Maybe some weirdo might buy something.
