Using Optimizely on Dynamic Sidebars (all pages)

[#1]

Hi

I'm using Optimizely for a wordpress website. I would like to run some tests on the sidebar but I want to make it available on all pages that have that sidebar. 

When I create an experiment on optimizely it asks the URL where I'll run the experiment, however in this case it won't be a unique URL, but every single page (around 500) that use the same sidebar. 

How can I do that?

Have you looked into setting up custom tags on the pages and building an audience of these users?
