Supports All Amazon Associates Locales

Includes Germany, Japan, Italy, Spain, UK, US, Canada, France, Australia, India, China, Mexico and Brazil.

Works without JavaScript

Some visitors turn off JavaScript in their browsers for security reasons and most ads including Google Adsense will not show up to them. But this one works!

Automatic Insertion in Posts and Feeds

Just check where you want the product links to appear with auto-insert.

  • Static Contents Conversion – If you want the product link to be static, it is possible. This means if you deactivate the plugin, the converted contents will remain.
  • Detailed Visibility Criteria – You can enable/disable product links on the pages you want or do not want by post ID, taxonomy, page type, and post type.

Auto Link Conversion

Hyper links to Amazon products in posts and comments can be transformed into your associate links. This is useful if your site allows guests to post contents that include Amazon links.


Place the widget in the sidebar and select the unit you created. The product links will appear in where you want.

  • By Units – choose the created units to display in the widget.
  • Contextual Search – with this, you don’t have to create a unit. It will automatically searches products relating to the currently displayed page contents.

Shortcode and PHP Function

Insert the ads in specific posts and pages with the shortcode. If you want to insert in the theme template, use the PHP code the plugin provides to produce the outputs.

Filter Unwanted Products

If there are some items you don’t want to display, you can create a black and white list by description, title, and ASIN.

Custom Buttons

Visitors more likely click buttons than regular text hyper links. Define your custom buttons and insert it to the unit output.

Export Ads into External Sites with Feed

By subscribing to the product feed produced with the units you create as RSS or JSON, you can import them from other sites.

If you have a web site that can display RSS feed contents, just create a WordPress site somewhere with this plugin and fetch the feed from the site. If you are an App developer, you can just display the items from the feed without programming an API client.

Various Unit Options

  • Image Size – The size of thumbnails can be specified. It supports up to 500 pixel large with a clean resolution.
  • Sort Order – Shuffle the product links so that the visitor won’t get bored as it gives refreshed impression.
  • URL cloaking – You can obfuscate the link urls so it helps to prevent being blocked by browser Ad-blocking add-ons.
  • and more.

Customize Outputs

Besides the Item Format unit option which lets you design the output of a unit, you can create a custom template. This gives you freedom of customization and lets you achieve more advanced and detailed design.

Unit Types

  • Category – pick your category that matches your site topic.
  • Product Search – create a unit of a search result.
  • Item Look-up – display specific products.
  • Similarity Look-up – display similar products.
  • URL – list items from an external web source.

How to Create Own Template

Step 1

Copy an existing template that is located in ...wp-content/plugins/amazon-auto-links/template and rename the copied folder.

Step 2

Remove the files besides style.css and template.php as other files are optional.

Step 3

Edit style.css and template.php to customize the layout.

Step 4

Create a folder named amazon-auto-links in your theme’s folder. If you are using Twenty Thirteen, the location would be ...wp-content\themes\twentythirteen\amazon-auto-links.

Step 5

Move the working folder(the copied one) to it (the amazon-auto-links folder you just created).

Step 6

The plugin will automatically detect your template and add it in the template listing table. So activate it.

Upgrading V1 to V2

When upgrading v1 to v2, a few options will be lost. That includes:

  • Sidebar widget
  • The positions of the inserting area

These options need to be reconfigured.

How to Obtain Access Key and Secret Key

An access and secret keys are required to perform API requests. We need to deal with additional two separate Amazon services apart from Amazon Associates.

For detailed instructions, please refer to the To register as a Product Advertising API developer section.

Step 1 – Create a Product Advertising API Account

Before you create an access key, you have to make sure you have singed up with Amazon Product Advertising API.

Step 2 – Sign up with Amazon Web Service

Next, create an account with Amazon Web Service( At the top right pull-down menu, you can navigate to My Account/Console -> Security Credential.

Step 3 – Create an Access Key

In the Security Credentials page, find the section named Access Keys (Access Key ID and Secret Access Key) and click on that.

Then press the Create New Access Key button to create a key. Don’t forget to keep the secret access key as well. Amazon has changed the policy not to let the user to obtain the secret key later on.

Also note that at the point that an access key is issued, if you have not created an account with Product Advertising API, the key will be invalid. If that happens, delete the created access key and go back to the previous step.

You can check if your access key is valid or not with Scratchpad.


  • Embedding Links below Post
  • Widget Sample
  • Setting Page (Selecting Categories)
  • Setting Page (Creating New Category Unit)
  • Setting Page (Selecting Templates)



  1. Upload amazon-auto-links.php and other files compressed in the zip folder to the /wp-content/plugins/ directory.
  2. Activate the plugin through the ‘Plugins’ menu in WordPress.

Getting Started

  1. Go to Dashboard -> Amazon Auto Links -> Add Unit by Category.
  2. Configure the options and select categories.
  3. After saving the unit option, go to ‘Manage Units’ to get the shortcode or if you check one of the insert option, the links will automatically appear in posts or feeds depending on your choice. The widget is available in the Appearance -> Widgets page as well.


Do I need Amazon Associate ID to use this plug-in?

Yes. Otherwise, you don’t get any revenue. You can get it by signing up for Amazon Associates.

Do I need Amazon Access Keys?

For the Category and Tag unit types, no, you don’t need them. However, for the search unit type, you need them as the plugin uses Amazon API. However, for the Search unit type, and for some items such as %image_set% in the Item Format option, setting up API keys is required.

Yes, all unit types require Amazon access keys (as of v3.8.2). You need to issue a pair of keys on either the AWS site or the Amazon Associates page.

For that, you need to have an account with Amazon Product Advertising API. The keys can be obtained by logging in to Amazon Web Services and you need to get Access Key ID (public key) and Secret Access Key (private key).

More detailed instruction, please refer to the To register as a Product Advertising API developer or How to Obtain Access Key and Secret Key section.

What does a Unit mean?

A unit is a set of rules that defines how Amazon products should be displayed.

When you display Amazon products, you would specify a unit and the plugin will generate outputs based on the rules defined for the unit.

What would be the benefit to upgrade to the pro version?

With the pro version, unlimited numbers of units can be created. Also the number of categories per unit, the number of items to display per unit are unrestriceted as well. Please consider upgrading it. Amazon Auto Links Pro As of Pro 2.0.6, links can be displayed in multiple columns.

I get a blank white page after adding a unit to the theme. What is it? What should I do?

It could be the allocated memory capacity for PHP reached the limit. One way to increase it is to add the following code in your wp-config.php or functions.php
define( ‘WP_MEMORY_LIMIT’, ‘128M’ );
The part, 128M, should be changed accordingly.

I want to display product links horizontally in multiple columns. Is it possible?

Yes, with Pro!

I have a feature request. Would you implement that?

Post it in the support section. If it is feasible, it will be included in the to-do list in the Other Notes section.

I get Amazon product links everywhere on the site after creating some units. How can I restrict them to certain pages?

Go to Dashboard -> Amazon Auto Links -> Manage Auto-insert. There turn off unnecessary auto-insert items. You can edit their definitions and define where units should be displayed.

My credentials do not seem to be authenticated. How can I check if my access keys are the correct ones?

Try Scratchpad to make sure your keys work there as well.


Great Plugin and Awesome Support

This plugin is very easy to use! And Michael is very quick to respond to requests! I love that I can now link my readers to Amazon smile - they get to donate to a charity and I still get the commission! Win-win!

Excellent plugin and great support

We are using the plugin in a directory and it works very well. It's easier than ever to show your affiliate links in several places on the templates, without all the hassle of doing it manually. Highly recommended!
