ChatGPT Ads Context Hints: The Complete Guide
Context hints are the targeting engine behind ChatGPT Ads. They describe which conversations your ad shows up in — not what people type, but what they are trying to solve. This guide explains how they work, what separates a great hint from a wasted one, and gives you ready-to-use examples you can adapt today.
What is a ChatGPT Ads context hint?
In OpenAI Ads Manager, campaigns are structured as Campaign → Ad Group → Ad. At the ad group level you write a context hint: a short description of the conversations where your ad should appear. The platform then matches ads to relevant ChatGPT conversations and shows them as labeled ads beneath the answer.
The key idea: ChatGPT Ads targets situations, not searches. A person rarely types "buy magnesium" into ChatGPT — they ask "which magnesium is best for sleep, glycinate or citrate?" The hint tells the system to show a supplement ad inside that specific comparison conversation.
Context hints vs keywords
| Keyword targeting (Google) | Context hint (ChatGPT Ads) |
|---|---|
| Matches the search query a user types | Describes the conversation and decision a user is in |
| Captures existing demand — people actively searching | Reaches mid-research users who have not searched yet |
| Literal words, match types, negatives | Situational description, one to two sentences |
That is why ChatGPT Ads works well for research and consideration traffic — users in the middle of deciding, before they ever open a search engine.
What makes a good context hint
A good hint describes a specific situation: who the user is, what they are comparing, and the decision they are still weighing. If you can picture the exact conversation, the hint is probably specific enough.
E-commerce / Supplements
“Users comparing magnesium supplements for sleep, deciding between glycinate and citrate forms, and reading about third-party testing.”
SaaS
“Small business owners comparing email marketing tools, frustrated with deliverability, and weighing pricing against features like automation and segmentation.”
Agencies
“Marketing agency owners researching how to run ChatGPT ads for clients, new to OpenAI Ads Manager, and looking for campaign structure and tracking guidance.”
Home Services
“Homeowners comparing HVAC replacement quotes, unsure between heat pump and furnace, and reading about installation costs and rebates.”
Bad context hints (and why they fail)
- "magnesium, sleep, supplements, best magnesium, magnesium for sleep" — a keyword list, not a situation.
- "coffee, coffee beans, best coffee" — too broad, no problem or decision described.
- "our amazing product, quality, great value" — describes the ad, not the conversation it should appear in.
How to write a context hint: the formula
1Who
Describe the type of person (homeowner, agency owner, SMB marketer).
2What they are doing
The research task or stage — comparing, deciding, troubleshooting.
3The decision point
The specific choice they are weighing (glycinate vs citrate, heat pump vs furnace).
4The signal
Something concrete they are reading or checking (third-party tests, rebates, pricing).
Combine the four pieces into one to two sentences. OpenAI recommends a single focused hint per ad group — test different situations as separate ad groups rather than stuffing everything into one hint.

- Writing a keyword list instead of a situation description.
- Describing your product features instead of the user’s conversation.
- Trying to cover every audience in one hint — split them into separate ad groups.
- Ignoring the decision point (what the user is still comparing).
- Not testing: context hints, like all targeting, need iteration to find winners.
