What pricing models are available?
ChatGPT Ads currently support two buying models: CPC (Clicks objective) and CPM (Views objective). The choice should be based on the business goal, not habit from other platforms.
| Objective | Buying model | Best fit | Main risk |
|---|---|---|---|
| Clicks | CPC | Traffic, leads, sales, content visits | Paying for clicks before proving quality |
| Views | CPM | Awareness, launch visibility, category education | Optimizing for exposure without action signal |
What is a realistic first test budget?
A realistic first test budget is the amount required to collect enough click and conversion signal without risking too much spend on an unproven channel. Frame the first test as answering whether specific conversation themes produce qualified traffic — not proving immediate profitability.
Use this formula for a click-based test: Test budget = target clicks × expected CPC
| Target clicks | $3 CPC | $4 CPC | $5 CPC |
|---|---|---|---|
| 100 clicks | $300 | $400 | $500 |
| 250 clicks | $750 | $1,000 | $1,250 |
| 500 clicks | $1,500 | $2,000 | $2,500 |
| 1,000 clicks | $3,000 | $4,000 | $5,000 |
How should you choose CPC or CPM?
| Situation | Better starting objective | Reason |
|---|---|---|
| Lead generation audit offer | Clicks | Need landing-page visits and lead quality data |
| Ecommerce product collection | Clicks | Need product-page engagement and purchases |
| Brand launch | Views | Need exposure more than immediate action |
| New category education | Views | Users may not be ready to click yet |
| Retargeting-style comparison content | Clicks | Need to test high-intent traffic |
How do daily budgets work?
OpenAI documentation says daily budgets are treated as average daily budgets. Starting June 9, 2026, spend may exceed the daily budget on a given day, but OpenAI says it will not spend more than twice the daily budget on a single day or seven times the daily budget over a week.
| Daily budget | Possible max single-day spend | Weekly spend cap (7× rule) |
|---|---|---|
| $25 | $50 | $175 |
| $50 | $100 | $350 |
| $100 | $200 | $700 |
| $250 | $500 | $1,750 |
| $500 | $1,000 | $3,500 |
What should you calculate before launching?
Calculate the break-even conversion rate before launching. This prevents overreacting to CPC or CPM before you know what the economics require.
Formula: Required lead conversion rate = CPC ÷ value per lead
| Avg CPC | Value per qualified lead | Required qualified lead rate |
|---|---|---|
| $3 | $100 | 3.0% |
| $4 | $100 | 4.0% |
| $5 | $100 | 5.0% |
| $5 | $250 | 2.0% |
How should ecommerce advertisers model cost?
Ecommerce advertisers should model contribution margin, not revenue. A $100 order at 40% gross margin can support a different acquisition cost than the same order at 10% margin.
| AOV | Gross margin | Gross profit | Max CAC at break-even |
|---|---|---|---|
| $75 | 40% | $30 | $30 |
| $150 | 45% | $67.50 | $67.50 |
| $300 | 50% | $150 | $150 |
| $800 | 35% | $280 | $280 |
What can different budget levels answer?
| Budget range | What it can answer | What it cannot answer reliably |
|---|---|---|
| $250–$500 | Setup, approval, tracking, early click quality | Profitability by audience or product |
| $500–$1,500 | CTR, CPC range, landing-page fit, early conversion signal | Long-cycle ROAS or LTV |
| $1,500–$5,000 | Stronger creative and ad group comparisons | Full incrementality |
| $5,000+ | Better funnel and revenue analysis | Guaranteed scale |
