It's been about a year since I was really active in affiliate sales through Amazon, having lost faith in the same-o-same-o conversion rates. I think somewhere along the lines I forgot that I need to be more responsible for the traffic driven to them in the first place.
A few, recent, CSS tweaks, a little repositioning and viola! a 1.05% increase in Amazon Affiliate Sales. Right where it counts too, high-end electronics. Nothing better than seeings a single sale bring in 50.00+.
On a hunch, I also redesigned and repurposed a long dead domain of mine, cheatfu.com. On hour of tweaks and a bit of original/lazy CMS construction and we're at $1.00 Adsense revenue. I've said it before, a buck a day adds up. Besides, it was literally doing nothing, zilch.
Don't lose faith in yourself, your design or ingenuity
