Ad groups help organize your campaigns into focused themes and include context hints, which help determine how your ads are matched to relevant conversations in ChatGPT.
Each ad group contains:
Ad group title
Context hints: describe the conversations, topics, or keywords where your products or services may be relevant; these hints guide matching but are not exact-match targeting rules
Maximum CPC bid, for campaigns with a Clicks objective; for campaigns with a Reach objective, this field does not apply
Writing effective context hints
Context hints help ChatGPT understand the types of conversations your ads should be eligible for.
Think of context hints as broad thematic signals, not exact keyword matching.
Good context hints:
Describe the user intent or topic area
Stay closely related to your ad group theme and ads within the ad group
Write context hints that describe the types of questions, needs, or situations a user might bring to ChatGPT, rather than just listing standalone keywords
Prioritize relevance over broad coverage
