In a fictional example, “event lighting” names a product category. “Temporary lighting where power sockets are unavailable” describes a practical condition that can change which solutions fit. The latter may provide useful advertising context, but only if the offer actually meets that condition.
Working with constraints in ChatGPT context hints therefore means choosing the limitation that explains the customer’s decision. It does not mean collecting as many details as possible. OpenAI’s targeting documentation describes hints as additional context about ads. They are not exact-match keywords and do not guarantee delivery in a particular conversation. A customer requirement written in a hint therefore does not become an enforced rule about who can receive the ad. This method concerns choosing which need the draft should describe.
Distinguish requirements from preferences
A requirement means that the offer does not suit the task if the condition is unmet. A preference can influence selection without excluding alternatives. In a fictional lighting case, having no power socket may be a requirement. A preferred housing colour may be a preference unless a specific situation makes it necessary.
Ask what the customer would do if the condition were unmet. Could a different arrangement still work, or would the offer fail to support this task? The answer helps distinguish a decision criterion from an adjective that merely sounds specific.
Do not automatically turn the product’s strongest feature into the customer’s requirement. A product being easy to carry does not prove portability matters in the researched situation. Check the task and product evidence separately before connecting them.
Write the condition without solving it immediately
First write “the customer has no power socket at the place of use”. Do not immediately replace that with “the customer needs our battery-powered solution”. The first sentence leaves room to investigate duration, setup and other conditions. The second jumps directly to selling.
Next, verify the actual offer. What use is intended? Which conditions apply? Are accessories or preparation required? This guide does not establish technical limits for a real lighting product. It identifies the questions to answer before approving a requirement-led hint.
Use the hint evidence check to connect the condition with current product documentation. A requested capability remains a request until the offer’s support has been confirmed.
Choose the condition that matters most in this description
A task may have several simultaneous requirements. That does not mean one hint needs to contain the entire specification. Choose the condition that best explains relevance, then check that an omitted requirement does not make the sentence misleading.
| Task in the fictional example | Condition to assess | Editorial decision |
|---|---|---|
| Light at a temporary location | No socket where illumination is needed | Possible central context if supported |
| Light throughout the event | Required operating duration | Verify rather than assume |
| Match other equipment | Preferred housing colour | Keep only if it changes suitability |
The most important condition may be the one that stops the draft being used. If the necessary duration is unsupported, a cordless design alone is insufficient. Rewrite the description around another situation or choose a different offer.
Review the combination of requirements
Two conditions can be reasonable separately but incompatible within the same offer. Easy movement and extended operation, for example, may require checking the specific arrangement. Do not combine the strongest capabilities of different models or packages into one imagined product.
Confirm that the correct version is being advertised. If an accessory is necessary, the meaning of the hint should match the way the offer is presented. The compatibility guide addresses the particular questions that arise when a requirement concerns other equipment.
Keep a short internal note of the conditions checked together. A later writer can then understand why the final wording is narrower than the initial idea. A removed detail should not return simply because it sounds persuasive.
Establish whether the customer can change the condition
Not every practical obstacle is fixed. In the fictional lighting case, the organiser might move the activity closer to a socket, split use into shorter sessions, or change the installation position. Ask what that adjustment requires and which parts of the task it changes. A condition can be negotiable without being unimportant.
Keep the original requirement separate from the accepted alternative. “No socket in the preferred location” describes a different situation from “no access to mains power anywhere on site”. The first may permit several solutions. The second narrows the options more firmly. If the customer accepts moving the activity, the writer should not continue presenting battery operation as the only relevant solution.
Record who confirmed that an adjustment is possible. A salesperson suggesting an extension cable does not establish that the customer’s site or working method permits one. The suggestion can become a follow-up question, but it should not silently become an assumption in the advertising brief.
Which constraint anchors the description?
- No socket on site
Possible context for a verified solution.
Checkpoint - Full required duration
Unknown support blocks a broad promise.
Reconsider - Possible adjustment
Moving the activity changes the requirement only once the customer confirms it is possible.
Checkpoint
Let a decisive requirement determine the draft’s status
Give each proposed situation a clear decision. A confirmed requirement met by the offer can anchor a hint. An unknown requirement needs investigation. An unmet requirement rules out that particular use case, even when the other features fit well.
If lighting is needed throughout an event but operating duration is unverified, do not simply write “cordless event lighting” and treat the problem as resolved. The broader description can conceal the same gap. Verify the duration or choose another supported situation. Equally, do not treat wording such as “not for long events” as a negative keyword or as assurance that those needs will be excluded from ad delivery. The negative wording review separates a customer’s obstacle from an attempted delivery restriction.
Once the central requirement is selected, the hint specificity guide can help refine the detail level. Before that stage, the working note needs the customer’s condition, the offer’s confirmed support, and any adjustments the customer can actually make. It should also identify the case where the combination fails. A requirement then provides a reason for an editorial decision rather than decorative detail in a longer sentence.
Use the targeting and relevance overview to place the requirement in the campaign brief. The condition explains suitability; any restrictions on where or to whom ads may be delivered need separate handling.
