When scaling, is it a good idea to mix direct pop buys with DSP traffic?

[Flavor]

Mixing direct pop buys with DSP traffic can be helpful when scaling because it gives access to more traffic sources. Direct buys often give more control over placements, while DSPs can open up new supply in one place without dealing with many networks. It also helps compare performance between both sides. But it’s important to track each traffic type clearly so you don’t mix results. Start with a small test on each, then increase budget based on what performs better. What do you think about using both methods while scaling pop traffic campaigns?
