Hey @bird@beehaw.org, I'll keep this on the post for now as its generic content at the moment.

There are two ways I'm going to suggest:

#1 Plausible's library

You mentioned using Plausible. did you know that if you include their custom event JS library you can just add class names to existing elements? If you're able to adjust the class names on your site this would be a nice and simple way to do things.

For example:

<button class="single_add_to_cart_button button alt plausible-event-name--Affiliate+Click plausible-event--product=product+name">Buy me</button>

For it to work you need to update your Plausible library to https://your-domain.com/js/script.tagged-events.js

The main issue here is that you have dynamic content being fed back to Plausible at the same time, which this process wouldn't help with unless you can tell you CMS to drop the name of a page's product into the class list. The example above shows what this would look like.

#2 - Custom JavaScript

The other route is just adding in custom JS. We could create a fun little library to add lots of customisation in, but we can keep this quite simple, by pasting the following code at the bottom of a page's body element.

(function(){
  var target_elements = document.querySelectorAll(".single_add_to_cart_button");
  for (var i=0; i<target_elements.length; i++) {
    target_elements[i].addEventListener("click", function(){ plausible("Affiliate Click", { props: {product: document.title} }); })
  }
})();

This code will:

• Look for all elements on the page that own a class name of "single_add_to_cart_button" (they can have other class names too)
• Look through all found, if any, and attach a click listener to those elements
• When a user clicks, the "plausible" function will be called and the desired parameters passed to it

If you want to know more about CSS selectors, W3Schools offers some simple examples to learn from.

You'll notice that this just covers the first of the two examples you gave. For your second example it would be good to have some additional information so that we can refine the click listener. For example, are each of these "link" or "button" elements, such as:

<a href="http://other-domain.com">View on Etsy</a>

If you're happy to DM me an example URL on this site, I can give you a complete example for the second set of click listeners?
