Audio hits 90%+ completion 1, highest of any format. But no click path exists 2. The only bridge is IP-matching listener IPs to advertiser pixels 3 — probabilistic, household-level, broken on ~40% of mobile-carrier IPs. Promo codes catch only ~15%. The gap between completing and proving action defines this format 26.
