Display Amazon Associates Links with Minimal Effort

Still manually searching products and pasting affiliate links in WordPress posts? What happens if the products get outdated? With this plugin, you do not have to worry about it nor trouble to do such repetitive tasks. Just pick categories which suit your site and it will automatically display the links of decent products just coming out from Amazon today.

The links are tagged with your Amazon Associate ID. This WordPress plugin supports 18 Amazon locales and works even on JavaScript disabled browsers. Insert the ads as widget or place generated shortcode or PHP code where the links should appear.

If you want to search a specific product, yes, you can do that too. If you are good at HTML and CSS coding and know a little about PHP, you can create your own template! That means you can design the layout.

Display affiliate links along with your posts with this plugin to generate actual income with minimal efforts.

Compatible with PA-API 5!

As of 2019/10/31, Amazon ended PA-API v4 and your site may no longer be able to display Amazon products with old API keys. In that case, regenerate keys on the Amazon Associates member’s area and you are good to go!

Migrate from Amazon Associates Link Builder

Are you looking for an alternative to the discontinued Amazon Associates Link Builder plugin? If so, this plugin can take care of their shortcodes inserted with their Gutenberg block.

Just enable the option and you don’t have to edit thousands of posts to replace the shortcode.

Want to display a selected product in a post?

If you want to simply display your desired specific product in a post, don’t worry. You can do that too. Just paste the product URL in the post editor. No shortcode is required.

Supports All Amazon Associates Locales

Includes Australia, Brazil, Canada, France, Germany, India, Italy, Japan, Mexico, Netherlands, Singapore, Saudi Arabia, Spain, Turkey, United Arab Emirates, United Kingdom, Sweden, and United States. China is supported for the category unit type.

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.

Widgets

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.
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(http://aws.amazon.com/). 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.

ਅਕਸਰ ਪੁੱਛੇ ਜਾਂਦੇ ਸਵਾਲ

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 unit type, no but for other unit types, yes. 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.

Is the plugin compatible with PA-API 5?

Yes. The plugin is compatible with PA-API (Amazon Product Advertising API) 5.0.

I’m migrating from Amazon Associates Link Builder (AALB). Can this plugin display products with their shortcodes?

Yes, enable the option by going to Dashboard -> Amazon Auto Links -> Settings -> 3rd Party -> Amazon Associates Link Builder.

There you also want to set the Template Conversion option. Make sure you enable your desired Amazon Auto Links templates in Dashboard -> Amazon Auto Links -> Templates. Then reload the 3rd Party screen. There you’ll see active templates are listed for the conversion option.

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.

Is the China locales supported?

For the category unit type, yes. But for the search and contextual unit types, no as PA-API 5 does not support it.

good plugin for amazon affiliate business, easy of use and simple. recommend this plugin for all user that want to gain some money using affiliate business

carmelojm 27 ਅਕਤੂਬਰ 2020

Hay algún CSS o HTML para mostrar la lista de productos con un número? Lo que quiero es traer una lista de productos de Amazon y antes del título se muestre un número creciente.

perseusix 26 ਅਗਸਤ 2020

Sehr viel Potential, am Ende zählt aber wie die Produkte optisch angezeigt werden. Diesen Bereich fand ich extrem enttäuschend! Ich habe da schon den Anspruch, dass es gut aussehen soll. Gerade einmal EINE Vorlage ist vorhanden. Wenn man VIEL Zeit hätte kann man selbst EINE erstellen. Man wird dann schon zur PRO-Version gezwungen, doch auch die bringt nur hässliche und völlig überladene Produktanzeigen (laut Screenshots). Der Produktimport mit Kategorien fand ich dagegen sehr gut, deswegen auch zwei Sterne.
