Link Checker does just what it sounds like it does: it checks your links. Specifically, it verifies that a URL linking to Amazon.com is tagged correctly (or not). You can only earn referral fees through links tagged appropriately with your Associate ID or Tracking ID, so if you’re building your own links or modifying ones you’ve pulled from Associates Central or Amazon.com, use this tool to ensure you’ve constructed things properly.

If you’re itching to go far beyond links to include product descriptions, images, pricing, reviews, similar-product suggestions, and more in your content, the Product Advertising API is for you. This tool gives advanced users real-time access to the aforementioned product attributes, as well as to searching and sorting functionality — all for display on your own site! This is an advanced tool and can be a little too much for some users’ needs, so if you think you’re in that bucket, stick with SiteStripe. For those looking for lots more access, though, it’s a great solution.

If you have international readers — and most everyone on the internet does — you definitely need OneLink. This is a script you install on your site, that redirects your Amazon links to a user’s local Amazon marketplace. So for example, if you’re based in the US and you link to a specific book’s Amazon.com page on your site, a UK-based reader will be redirected to that book’s Amazon.co.uk page when they click. Of course not all products will be available in all markets — you can set your redirect preferences to Close Match or Exact Match. (Sub-tool alert: learn which corresponding products are available in other geographies by entering a product URL in the “Check matching products” section of the OneLink page.)

With OneLink installed, visitors can view your recommended products within their usual Amazon account, and see localized pricing and shipping information — without any additional steps. Note: to effectively add the OneLink code to your site, you first need to link your account with your international Associate account. Don’t worry: there’s a tool for that (see below).

If you’re a WordPress user, you know that for almost every website feature or bit of functionality you can dream up, a plugin exists to make it possible (and often, painless). It’s probably no surprise, then, that there’s an official Amazon Associates Link Builder WordPress plugin. Don’t let the name fool you — you can do a lot more than build links with this tool.

The primary purpose of the plugin is to build HTML shortcodes for displaying product-related content that would otherwise take a lot of coding know-how (and also a lot of access to Amazon product data — which the plugin gets through the above-mentioned Product Advertising API!). Via the plugin, you can build and display content as complex as image carousels and product grids (and a lot more), complete with real-time geo-targeted product info, with just a few clicks — no coding required.
