We have a series of category pages on our e-comm site. Each page can be sorted/filtered different ways. With each sort/filter the URL changes. How can I test the variations of this same URL to a single audience? I have tried setting up as A/B test, but the page delivery only allows for a single URL. I have tried using experience targeting, where I can add additional pages, but since the audience is the same, I can't add a second experience with the same audience but different URL.
I would switch back to A/B activity type. In regards to your previous statement: "I have tried setting up as A/B test, but the page delivery only allows for a single URL." That is not completely accurate. While you will only be able to designate one primary URL you do have the ability to specify additional URL parameters (By clicking "+Add template Rule") that can satisfy the URL requirement take a look at the screen-shot below where I demonstrate how to set this up. Additionally instead of is you can use contains to cast a wider net.
