Duplicate content in product listing

[erangalp]

We have "duplicate content" warning in our moz report which mostly revolve around our product listing (eCommerce site) where various filters return 0 results (and hence show the same content on the page). Do you think those need to be addressed, and if so how would you prevent product listing filters that appearing as duplicate content pages? should we use rel=canonical or actually change the content on the page?

I suggest using rel=canonical on those pages, but be aware that they may still show up in the moz report.

Thanks, David!
