Amazing Affiliates is the WordPress plugin that will help to monetize your Amazon Associates affiliated business. With this plugin you can finally monetize your website through the promotion of Amazon products (with Amazon Product Blocks)! Within seconds and without any coding skills!
Amazing Affiliates is designed to automate all the annoying time-consuming processes (i.e. calls through PAAPI5 Amazon Product Advertising APIs). With this plugin you will have more energies and time left to dedicate to the quality content that really matters to your website/blog success.
You just need to copy the link or the ASIN of the Amazon product that you want to display! The plugin will then automatically recognize the product, call the Amazon API for the latest data, create a product in your WordPress database and fill it with a title, image and description and affiliate product link. This product data will remain up to date and can be inserted wherever you want through the Amazon Product Blocks.
Thanks to the automation, you will have more time to dedicate to real content creation! 
Simple, effective and absolutely… amazing, this Amazon affiliate plugin will incredibly simplify your job as a marketer.
Made from Amazon affiliate marketers for Amazon affiliate marketers, this plugin is simply everything you’ve always searched to quickly scale and monetize your business.
And the best part has yet to come, since more exciting features are in development!
<h3>How it Works:</h3>
This plugin allows you to populate your affiliate website with Amazon Product Data taken directly through the Amazon Product Advertising API (PAAPI5).
Product Data in Amazon Cloud => PAAPI5 => Product Data in your website database
(You need Amazon Associates PAAPI5 credentials to use the plugin correctly, you can find them in you Amazon Affiliates Dashboard)
Product Data in your website database => Product Block => Product Displayed in your website Post
The information gathered through the APIs can be beautifully displayed through the “Amazing Product Block”. This particular block can be inserted in the website post content using the visual Gutenberg Editor of WordPress.
The amazon product blocks are designed to work efficiently in both mobile and desktop layouts and are customizable with:
<ul>
<li>Colorful wrappers with editable wrapper titles.</li>
<li>Customizable product titles.</li>
<li>Toggle buttons to show/hide the price and CTA fields.</li>
</ul>
Meanwhile, in the backend part of your website (i.e. your admin panel, in the plugin pages) you can also see the product’s stock availability, price, last update, etc… so that you can easily notice product with issues and promptly substitute them with a valid alternative and not even lose a penny!
While from the settings page you can activate an eye-catching animated banner in the “Amazing Product” Block that triggers whenever there is a certain % of discount set by you. Here you can also set a custom default sitewide text for the CTA button.
