ChatGPT Ads creative specs
Title and text limits, image size and format, and the ChatGPT Ads policies that most often get B2B ads rejected, with what IntentBid checks before launch.
A ChatGPT ad is a single card shown under an answer and marked as sponsored. It has four parts: a title, a short text, one square image and a landing page. Your business name and logo (favicon) come from your ChatGPT Ads account, not from the ad.
Specs at a glance
These are the limits at the time of writing. OpenAI is still adding formats, so check the live counter in ChatGPT Ads Manager if something looks different.
| Element | Limit | Recommended | What IntentBid checks |
|---|---|---|---|
| Title | 50 characters maximum | 16–24 characters | 3–50 characters |
| Text (ad copy) | 100 characters maximum | 32–48 characters | 1–100 characters |
| Image | Square (1:1), no larger than 1200 × 1200 px | 1200 × 1200 px | An image is attached, at least 640 × 640 px |
| Image format | PNG or JPG | JPG for photos, PNG for logos and text | PNG, JPG or WebP, up to 1.5 MB |
| Landing page | Reachable, not blocking OpenAI's crawlers | The page that answers the question | Present and valid URL |
Writing the title and text
The person has just read an answer to a question. Your card should feel like the next useful step, not an interruption.
- Title: the outcome or the offer, in plain words. "Close the books in 5 days" works; "The leading finance platform" does not.
- Text: add something the title does not say: who it is for, how it works, or what happens after the click. "Month-end close software for finance teams on NetSuite."
- Don't repeat the title in the text. OpenAI's guidance is that the copy should add new information.
- Write several title and text variations per offer. The system learns which ones fit which conversations.
Choosing the image
- Use one clear subject: the product, a person using it, or a simple visual of the result.
- Keep text on the image to a minimum. The title and text already carry the message, and small text is unreadable at card size.
- Avoid abstract stock art and busy collages. OpenAI asks for images that are simple and relevant to the message.
- Export at 1200 × 1200 px. The Creative studio makes the square from any photo, with a focus point so the subject isn't cropped.
Policies that matter most for B2B
ChatGPT Ads reviews the title, text, image and landing page together. These are the rules B2B advertisers run into most.
No claims your landing page can't back
Ads must be truthful, and OpenAI's ad policies prohibit unfounded claims about capabilities, pricing and outcomes. In practice:
- Every number in the ad ("5-day close", "30% fewer tickets", "from $49") must appear on the landing page, with context.
- "Best", "#1" or "leading" need a named, current source on the page, or leave them out.
- Customer names, logos and awards must be real and allowed by the customer.
- The landing page must describe the same product and offer as the ad. A demo ad that lands on a generic home page is a common reason for rejection.
No images that imitate the chat interface
Ads must be clearly distinguishable from the ChatGPT product experience. Don't use creatives that look like ChatGPT or another OpenAI interface, for example:
- A screenshot or mock-up of a chat conversation, message bubbles or a prompt box.
- Text styled as if the assistant were recommending you ("ChatGPT says…").
- OpenAI logos, the ChatGPT name as a badge, or interface icons.
Showing your own product's interface is fine, including your own chatbot, as long as it can't be mistaken for ChatGPT.
Other common reasons for rejection
- The landing page is broken, redirects somewhere unrelated, or blocks the OAI-AdsBot or OAI-SearchBot crawlers.
- Exaggerated results or fake urgency ("only 2 seats left" when it isn't true).
- Unprofessional or offensive language or imagery.
- Restricted categories (for example financial or health products) without the required qualifications.
Before you launch
The review step in IntentBid checks the title and text length and that an image is attached, and reminds you of the two policy rules above. It can't read your landing page for you, so open it next to the ad and check every claim. See B2B ad copy guidelines for how to write proof that holds up.
