Targeting & custom labels

custom_label_0–4 are prompt slots — Signal Packs, HHI matrices, and activation kits are not on platform DCO.

Last updated August 12, 2026

Signal Packs (HHI / weather / geo matrices, Google Ads Editor kits, VAST-per-segment) were a legacy kernel DCO plan. They are not available on platform-api.

What you can do today:

  • Put segment hints in the feed as custom_label_0 … custom_label_4.
  • Reference them in the template: "{{title}} for {{custom_label_0}} shoppers".
  • Slice rowIds so each engage is one audience (still ≤24 variants).
  • Traffic the resulting files yourself in Meta / Google / TikTok.

Compliance, socio-economic suppression, and activation-kit generation are not automated on this path. Targeting execution stays in your ad account.
