[plugin: Amazonify] Where to place code?

I have thrown code just about everywhere possible without any positive (or negative) effects. My goal is to place a right-sided widget using the following code: [amazonify]:omakase:300:250[/amazonify]

Since I am inexperienced, it is my understanding that Amazon will take a look at my site and then recommend the best products. I really need help guys, if someone could.
