I run several sites, one of which is mostly gun reviews. I know my audience on that site very well, and I can hand-select Amazon products that will sell. On some pages, I have ads for things like a P-38 can opener. They're around $3 each or $10 for 10. Something like 5% of my traffic clicks that ad, and 70% buys the product. Because it's so cheap, I make only a couple of pennies per sale... but the number of items sold bumps me from the default 4% commission for the month to 6.5% or more without working for it. On other pages I might link to a $400 rifle optic, or a $50 gunsmithing book. Because of all those little sales, I make $26 on that optic instead of $16 - it makes a big difference. I've put Adsense on those pages in the past, and it averages around 10% of the revenue I get from Amazon.
