How should I use Google Analytics to setup goals for this?
 

I have a site full of informational articles, as well as a handful of sales copy articles.

What I want to do is, I want to test to see which ones of the sales copy articles work best with each individual informational article.

I include a hyperlink call to action at the bottom of every informational article that sends them to the sales copy pages.

Can somebody give me some tips please on how I can do this?

You can use a number of tools to test which hyperlink call to action works best to generate clicks, from article to sales page, such as with the Calls to Action wp plugin (inboundnow.com), or with Google Optimize.

Google Optimize is free. I use it and Analytics together.
