Sure, I've worked with gaming companies that have run ads on Taboola and Outbrain, but I've never seen either of those channels represent a meaningful amount of spend for a gaming company. It takes a lot of work to iterate into performant a. creatives and b. targeting on those channels and the funnel tends to be very inefficient. When I have seen this be profitable (at low-ish scale), the games were core with very deep monetization.
