Sometimes your perfect target audience can be defined by a set of specific websites. For those times, allow-listed campaigns are a great option. If you need to be in front of folks who read your specific local news and weather sites because you're promoting a local event, just define what sites you'd like to place your ads on, and we'll get it done! The included sites do need to have ad space to purchase though, so make sure the sites you'd like to advertise on host ads (just visit the sites and see if you see other ads).
