Myth: Native and display are separate channels with separate audiences.

Myth: Native and display are separate channels with separate audiences.
Wrong. Much 'native' is display inventory wearing a costume, often the same users, same exchanges. Diagnose the overlap:
— Run both channels with identical conversion tracking and an overlap report
— Check the supply path — does your 'native' DSP source from the same SSPs as display?
— Compare frequency caps; if users hit both, you're double-paying for one person
— Look at placement IDs — 'native' and 'banner' units on one MFA page share a domain
— A/B identical offers across both and compare incrementality, not raw CVR
Supposedly native is a premium, distinct buy. Then why does deduplicating audiences cut your reach 30% with zero conversion loss? You were paying twice to reach the same tired clicker.
