Not all channels are equal out of the gate. Sequence tests to find traction fast without burning cash.
Match channel to how people buy your product: problem-aware (search), solution-curious (social), or impulse (UGC + influencers).
Start with paid social for scale and paid search for intent capture. Layer creator whitelisting once message/offer wins.
Use frequency caps, placement exclusions, and negative keywords from day one. Protect brand terms with a low bid.
After you have a working hook and landing page, creators add scale and social proof. Pay for content rights, not just posts.
A channel graduates when it hits target CAC for two weeks with stable creative. If not, pause it and recycle angles elsewhere.
