Targeting Guide

ChatGPT Ads Targeting (2026)

No keywords, no problem. The five targeting layers of ChatGPT Ads — context hints, geography, platforms, custom audiences, and landing relevance — and how to combine them.

Layer	What It Controls	How To Use It
Context hints	Conversation situations	The primary lever — describe buying moments, not keywords
Geography	Country → state/DMA/ZIP	Granular in the US; country-level broadly
Platforms	5 app/web surfaces	Target and report each surface separately
Custom audiences	Include / exclude lists	Your own user lists; regional limits apply
Landing relevance	Page ↔ ad match	Relevance-weighted auction rewards tight matches

Stacking the Layers

Start broad, then narrow. Launch with context hints + country targeting and let the auction learn for 7 days. Add platform splits once you see where conversions come from — desktop web and in-app browsers often behave very differently.

Custom audiences come last: exclude existing customers first (saves budget immediately), then test include-lists for high-value segments. Because the auction is relevance-weighted, tighter ad-to-landing matches lower your effective CPC — targeting and creative are one system, not two.

Frequently asked questions

How does ChatGPT Ads targeting work without keywords?

Ads match the topic and intent of the conversation. Context hints describe the buying situations you want; OpenAI matches ads to relevant chats. There is no keyword auction.

What geo targeting is available?

Country targeting everywhere, plus US state, DMA, and ZIP targeting. New accounts may start home-country-only until verification and spend requirements are met.

Which platforms can I target?

Five surfaces: Android app, Android web, desktop web, iOS app, and iOS web — each targetable and reportable separately.

What are custom audiences in ChatGPT Ads?

Advertiser-provided user lists for include/exclude targeting. EEA/Switzerland campaigns face personalization limits — check current guidance.
