Unfortunately the main channel for addiction or mental health is display/programmatic for this reason. Especially retargeting.
The display and native exchanges are much less sensitive to this content and it scales easily.
So for Facebook that’s a no brainer to move over to. Some people mention taboola and that’s one of many native networks we use but we buy programmatically, not direct so we aren’t in 5-10+ platforms, performance is better and CPMs are actually cheaper.
You can do display, native, pre roll, connected tv and radio. We handle a couple of big players in this space if you need tips.
Display won’t drive as many calls as search but you can do contextual, very granular targeting and drive a crapload of retargeting which I find superior to Facebook. Calls won’t be as high as Google but similar to Facebook.
