An experienced buyer may be new to a particular product category. A daily user may know every detail without ever having purchased the product personally. When a ChatGPT ad is intended for “beginners” or “experts”, the brief therefore needs to define the relevant knowledge. Otherwise the copy may explain the obvious or omit the distinction that determines whether the offer fits.
Knowledge level here is an editorial choice about what the copy assumes. It is not a claim that an advertiser can identify every reader’s competence. OpenAI’s targeting documentation describes hints as additional context, not exact-match keywords or a delivery guarantee. This guide concerns making an advertising brief understandable at the appropriate level.
Knowledge level becomes a useful writing choice once the customer task is clear. The targeting and advertising overview explains how that task connects to the offer the copy must describe.
Define the decision the reader needs to make
Start with the decision presented by the offer. For a fictional three-dimensional modelling course, the question might be whether it suits someone who can already create basic objects. For a service in the same field, the question may instead be whether the customer has material that can be developed.
Write down the knowledge required for that specific decision. “Understands basic concepts” is vague. “Can distinguish a completed drawing from an early sketch” is easier to assess. You do not need a complete competence profile, only the knowledge affecting the offer’s meaning.
For training, compare this with the actual course prerequisites. Simple ad language must not make an advanced course appear suitable for someone without the necessary foundations.
Separate vocabulary from task understanding
A reader can recognise a technical term without understanding how it affects a choice. Another may understand the problem well while describing it in everyday language. These are different gaps and should not be treated as interchangeable.
In a fictional acoustic consulting offer, one customer may know the word reverberation but remain uncertain about the appropriate assessment. Another may say that speech blurs together in a meeting room without using the technical term. Both can have a relevant need to understand the service.
First describe the task through the needs brief. Then mark the words needed to distinguish this offer from another. A technical term that changes the service scope may need to remain, accompanied by a short explanation.
Create two knowledge profiles without stereotypes
| Question | Less category knowledge | More category knowledge |
|---|---|---|
| What needs explanation? | The task the service helps address | The specific part of the task it covers |
| What must remain visible? | Important prerequisites | Differences in method, version or scope |
| What might be unnecessary? | Multiple undefined terms | A lengthy account of a familiar basic problem |
The table describes copy needs, not types of people. Experts also benefit from clear writing. Someone new to a category does not need a patronising tone. The aim is to choose the explanation that supports the current decision.
Do not mistake a confident tone for knowledge. A person may sound certain while misunderstanding a condition. Research should investigate how they describe and perform the task, rather than how professional their answer sounds.
Write the core offer, then choose its explanation
Preserve the same verified offer across knowledge variants. In the acoustic example, the core may be a specific assessment of a meeting room. A less familiar reader may need to understand which everyday problem the assessment investigates. A knowledgeable reader may need the assessment’s precise scope.
Do not broaden the service to make the wording sound simple. “We make your room work” is not merely a clearer version of a bounded assessment. It changes the promise. A short description of the actual work is often more useful than a general outcome word.
If a central term has several meanings, use the ambiguity review. Establish its meaning in this task before carrying it into contextual descriptions for the ad. Adding more technical detail does not help if the key term remains unresolved.
Choose the level before choosing a variant
For the fictional acoustic service, an internal brief might say: “The reader recognises the meeting-room problem but does not know what an assessment covers.” The leading message then needs to explain the work offered. Another brief might say: “The reader has commissioned an assessment before and is comparing its scope.” Distinguishing included work from separately commissioned work becomes more useful for that decision.
Choose between these descriptions using evidence about the current customer task. Do not let colleagues’ own professional knowledge automatically set the level. When evidence is missing, start with a concrete account of the work and check whether a reader understands it. Keep the assumed level marked as a working hypothesis until that interpretation has been examined.
Choosing assumed knowledge is a different decision from translating every technical term. First decide what the reader needs explained; then choose the words. Two variants that replace “reverberation” with a simpler expression while leaving the same question about scope unanswered have not yet resolved the knowledge-level choice.
One assessment, different explanations
- Less prior knowledge
The reader knows the problem but needs the assessment’s purpose explained.
- More prior knowledge
The reader knows the process and needs to compare what is included.
- Shared boundary
Assessment does not mean installation.
Checkpoint
Inspect the conclusion a reader draws
Ask someone with the intended prior knowledge to read the draft and explain what is offered, who it suits and what happens next. Do not only ask whether the copy is clear. A quick yes does not show whether the interpretation is accurate.
If the reader describes a broader promise than the brief intends, revise the wording. If they understand the offer but struggle with one term, a short explanation may be enough. If the whole decision is unfamiliar, the selected advertising task may be too far along in the process.
Record the type of misunderstanding. This makes feedback useful for the next draft. “Too technical” gives less direction than “the reader thinks installation is included, although the offer only covers assessment”.
Finish the brief with one sentence naming the knowledge assumed and another stating what the ad must explain. Check that the explanation has not changed the offer. The copy should be respectful to a less familiar reader and precise for a more knowledgeable reader, even when one of those levels determines the leading message.
Sources and scope
Determine which knowledge an ad can assume so the offer is understandable without losing technical distinctions that affect suitability.
