Playables in UAC tROAS campaigns

Yay or Nay ?

Are playables actually tap into new unreachable inventory as oppose to when using only banner, video, text assets ?

Has anyone been able to experience actual performance improvement by using Playables ?

Yes, playable ads can genuinely unlock additional inventory in UAC tROAS campaigns. I've seen cases where they improved ROAS and contributed a significant share of voice, although those cases were quite rare.

My experience is from about five years ago, so it may not be fully relevant today. Given the current landscape, I'm also not convinced that investing in playable ads for UAC would yield a better return than allocating that budget to AppLovin.

i never saw them getting spend on AUC tbh and I have tested them multiple times

For me, playables tend to work much better in DSPs either as standalone ads or IECs (interactive endcards)
