You can use affiliate links after the fact. You don’t have to decide upon building a WordPress site that you’re going to optimize it with Amazon affiliate links. You can decide down the road that you want to give affiliate marketing a try and, consequently, revisit old content, embed affiliate links within it, and start generating revenue that way--especially if your old content is finally starting to take off.
However, if you’re running an e-commerce site, conducting product testing and reviews, or offer Amazon product coupons, then you probably will want to use a WordPress Amazon affiliate theme. To be clear, these themes aren’t usually made specifically for Amazon affiliates. Instead, what you’ll want to look for are e-commerce or multi-purpose WordPress themes that are:
The AAWP plugin conversion and CTR is amazing! Once I started to use the plugin on all my sites, I saw an immediate increase in commissions. It also makes my sites look much more professional. I love tapping into the Amazon API to pull images, make my own charts and tables plus I know I am abiding by Amazon's TOS. AAWP is a must have tool for anyone running Amazon affiliate websites!
My 10-year-old son brought home a book from our park’s free library box. It was a biology textbook – teachers edition. He said it looked interesting and hey, it was free (having no idea you could sell it). I scanned it in my Amazon seller app and realized it was worth around $150. He was so excited. We listed it for sale for $130 and it sold! Going to tell him, he just made $130!
I recognize that the list above is short; however, that’s because Amazon affiliate marketing really doesn’t require a specialized theme in order for it to work well (unless it’s one of the unique cases noted in the themes above). Instead, you’re better off using WooCommerce if you want to build a full affiliate store or simply stick to the WordPress theme you currently have and add affiliate plugins to the mix.
