How do I use GPT to write ads that are accurate?

Use GPT to draft and compare messages from a verified brief, not to invent the offer. The strongest workflow separates facts, creative options and launch approval. A fluent headline is still a draft until its claims, destination and platform requirements are checked.

What should go into the brief?

Provide the audience, customer problem, product or service scope, confirmed price conditions, delivery limits, approved proof, tone, destination and prohibited claims. Mark unknown information explicitly. Use public or authorised business material; do not upload private customer correspondence simply to make an example more detailed.

A reusable prompt

Using only the approved facts below, draft three distinct advertising angles for this audience. For each, give the customer problem, headline, supporting copy and matching landing-page section. List every factual claim with its source. Mark missing information as unknown. Do not invent results, discounts, urgency or guarantees. Do not publish or change a campaign.

Then supply the actual facts, intended language and channel. This is a writing prompt, not a mechanism for purchasing paid placement inside ChatGPT.

Review the output in two passes

1. Check truth: price, scope, dates, availability, evidence and rights.
2. Check usefulness: can the reader tell what is offered, for whom and what happens next?
3. Check distinctness: each variant should test a real angle rather than changing synonyms.
4. Adapt the approved copy to the current platform fields and policies.
5. Review the Bulgarian translation with a native speaker and inspect the real mobile ad and page.

How do I judge the drafts?

Score clarity and factual support before stylistic preference. A developer or decision model can flag missing sources and policy risks, but it cannot certify profitability from wording alone. After publication, compare verified outcomes using an agreed test design. Keep the original brief and rejected claims so a later automation does not silently reintroduce them. For paid placement in ChatGPT, follow the separate official-platform preparation guide; for production, see the agentic workflow.
