Does the math in the post seem plausible to anyone who uses affiliate links? A .001 click-through rate to Amazon seems plausible, but unless I'm mistaken the author of the post is using that a conversion percentage (i.e. a click-through + purchase), which seems way too high to me, by an order of magnitude or more. Does anyone have solid numbers for click-through to purchase rates of affiliate links?
