Showing Ads Based on Tag/Category

This is a relatively old topic, but wondered if anyone knows how to set up conditional ad serving based on category, tag, or something else using Google’s DFP?

This old topic describes how to do it more manually – https://www.ads-software.com/support/topic/show-bannersads-based-on-category?replies=6
But that’s not practical with 100s of tags and special once-in-a-while tags we might want to use.

Since I use Google DFP, I *think* there’s way to somehow pass the tag names or category names into DFP and let Google do the conditional work. But I’ve got no idea what I’m doing in there.

So, this might move outside of wordpress and into DFP expertise, but any links or experts out there would be much appreciated!
