I’d stick with Amazon if I were you. All of my Amazon sites only have Amazon affiliate links. If you use Google Adsense display ads on your site, you’re literally taking people away from your site for the sake of just a few cents with these type of ads. If you direct them just to Amazon, then you have a greater chance of earning more money from that click.
It is important to note, however, that StudioPress is now a subsidiary of WPEngine which is the company that actually does the web hosting on which StudioPress’s Genesis framework runs. The affiliate program only works with choosing the StudioPress framework and themes, not the actual hosting on WPEngine. WPEngine has a separate affiliate program for its hosting services, which yes, is a bit confusing.
Hey Amos, great question. The length of your review blog posts will depend on the specific keyword you’re targeting and the competition. I would Google the term and look at who’s ranking in the top 10, then check how long these articles are. I use a free Chrome extension called Word Counter Plus which makes it easy. Once you see how long competitor articles are, make yours longer and higher quality. 🙂
If you have built up an email list, you could also promote your affiliate offers via email promotions. Just make sure you build up a relationship with your audience first instead of going for the hard sell straightaway. The emails you send out must contain your affiliate links to products so when your audience click through. the sale is attributed to you. 
However, affiliate marketing isn’t just about marketing your partners’ goods, or at the very least it can be about much more than that. Affiliate marketing is also an opportunity to create your own website or some other form of content and get paid to do so, because you’ll be running ads and providing other links to things your audience will genuinely want to buy, at least if you combine your affiliates and your interests correctly.
It doesn’t let the link influence its decision of whether to include or omit anything it deems worthy of inclusion, as to do so would damage its trust rating. There’s a lot you can learn from taking this stance. Remember, your site should be built with your visitors in mind, not profit. Take care of your visitors and the profits will take care of themselves!
Thank you very much. I signed up to a few here and I am very grateful to you for making all of this valuable information available – you have saved me time. I could not sign up to Shopify as it just kept on reloading page to SIGN IN and not create a new account – confusing. VigLink does not allow a new account sign up either.. Rakuten did not say if they charge to be apart of their affiliate prog and actually there is no sign up for that option. If you can help me with these three prog’s… Read more »
