Welcome to the Q&A Forum

I have a pretty big directory site using Wordpress with lots of "locations", "features", "listing-category" etc.... Duplicate Content: https://www.thecbd.co/location/california/ https://www.thecbd.co/location/canada/ referring URL is www.thecbd.co is it a matter of just putting a canonical URL on each location, or just on the main page? Would this be the correct code to put: on the main page? Thanks Everyone!
