I see alot of new people are jumping on this band wagon. Might I be a small voice of reason for just a moment? Amazon pays every 90 days. Google and Amazon hate MFA[mazon] sites. Amazon LOVES to make you work your lil butt off as an affiliate then on that 90th day, either take away all your earnings or ban your account. Google will probably sandbox/deindex your site if they manually review it. Google might do it anyway when their crawler sees that all your content is taken from Amazon (not as likely but it happens).
Consider this a warning for those short on cash and/or time. Make sure your entire marketing career does not depend on this one project (as it so often does when you're starting out). Don't put any time or money into this unless you're willing to risk losing it all. IM is about risks and the greatest risk takers are usually the richest, but it's hard to risk alot if you only have a little.
The best way to do this is to build unique content on a daily basis and then slowly add more and more amazon products. Try adding two to three products a day with unique 400-500 word articles written about each one. That's the key to long term success here. If you look like MFA[mazon] you will be treated like a MFA.
Anyway, just my $.02 for those why may not know.
