ChatGPT Ad Creative: Formats, Specs & What Converts

ChatGPT Ad Creative

ChatGPT runs two ad formats in 2026: banner ads that appear at the bottom of answers, and product feed ads for ecommerce brands with a connected catalogue. Both are clearly labelled as sponsored, visually separated from the response, and never influence what ChatGPT says.

The formats look simple. A logo, a title, a line or two of copy, a link. That simplicity is exactly why creative discipline matters more here than on any other paid channel: there is nowhere to hide. This guide covers the specs for both formats and the copy patterns that actually convert.

TL;DR: ChatGPT Ad Formats in 2026

  • Banner ads in answers. A single sponsored unit below a relevant response: small advertiser logo, ad title, body text, click-through link.
  • Product feed ads. Shoppable cards showing product name, price, image, and details, pulled from a connected catalogue.
  • Headline spec. Around 30 characters, capped at 36.
  • Body copy spec. Roughly two sentences, around 19 words, with at least one specific number.
  • CTA spec. Name the action or offer. "Start free trial", not "Learn more".
  • Tone rule. Flat, calm, direct. Hype reads as out of place next to ChatGPT's voice.
  • One unit per response. Users see a single ad unit when there is a relevant match, so there is no position two.

Format One: Banner Ads in Answers

The core unit. When a user's conversation matches an advertiser's targeting, a sponsored card appears below the end of ChatGPT's response. The unit contains a small advertiser logo, an ad title, body text, and a click-through link. It is labelled as sponsored and sits visually apart from the answer.

Two properties shape everything about how you write for it.

It appears after a complete answer. Your ad is not competing with other ads for attention. It is competing with the completeness of the answer above it. The user has already been helped. Your ad has to add something: a specific product, a concrete offer, a next step the answer could not provide.

There is one slot. OpenAI shows a single ad unit below a response when there is a relevant match. Winning the auction means being the most relevant advertiser for that conversation, not the highest bidder. Creative relevance is a delivery lever, not just a conversion lever.

Format Two: Product Feed Ads

For ecommerce brands, ChatGPT shows shoppable product cards inside relevant conversations: product name, price, image, and key details, pulled directly from a connected catalogue rather than written manually.

Setup runs through a product feed uploaded via SFTP, with a catalogue minimum of around 1,000 products as of mid-2026. Titles, descriptions, prices, and images come straight from the feed, which makes feed hygiene the creative work: clean product titles, accurate attributes, and strong images determine how the cards render. The full walkthrough is in the product feed ads guide.

If you sell physical products at catalogue scale, run both formats. Banner ads capture category research ("what should I look for in a standing desk"), feed ads capture product-level intent ("best standing desk under $500").

The Specs That Matter

From testing across live campaigns, the numbers that hold up:

Headlines: around 30 characters, capped at 36. Short enough to scan in a single glance. The best-performing headlines name the product category and one differentiator. "CRM built for 10-person teams" beats "Transform your sales process".

Body copy: two sentences, roughly 19 words. And at least one specific number: a price, a percentage, a count. Specificity reads as credible next to an AI answer. Vagueness reads as filler.

CTA: name the action or the offer. "Start free trial", "Get 20 per cent off", "Book a demo". Never "Learn more". The user has just finished learning; the ad's job is to offer the next step.

What Converts: Five Creative Patterns

Match the conversation's register. ChatGPT's voice is calm and considered. Ads written in social-media hype voice (pattern interrupts, vague superlatives, exclamation marks) underperform consistently. Write like a knowledgeable colleague making a recommendation.

Lead with the specific, not the brand. Users in ChatGPT are mid-research. "HIPAA-compliant CRM with audit logs from $49" gives them a reason to click. "The world's leading CRM" does not.

Rewrite, never port. Winning Meta and Google creative depends on mechanics that do not exist here: scroll interruption, keyword match, visual noise. Flatten your winners before testing them. The angle can survive the move; the execution cannot.

Ship distinct angles, not rewordings. OpenAI's system matches title and copy variations to more conversations, so multiple genuinely different angles per audience hint outperform five versions of the same line. Price angle, outcome angle, credibility angle, speed angle: each one unlocks different conversations.

Align the landing page to the conversation. The click should feel continuous. If the ad appeared under a conversation about pricing, the page should answer pricing questions above the fold. A generic homepage after a specific conversation reads as bait and switch, and post-click experience feeds back into delivery over time.

Henry walks through the full creative playbook on screen: format anatomy, hook patterns, real examples, and how to brief a first round of ads. The fastest way to calibrate your eye before writing.

Testing Creative Without Burning Budget

Structure each audience hint with three to five distinct angles at launch. Give the auction 72 hours untouched, then read the data weekly. Below 0.35 per cent CTR after 50 clicks, pause the ad. Between 0.35 and 0.68 per cent, iterate the weakest element (usually the headline). Above one per cent, feed it budget and build the next variant from its angle.

Creative iteration is where campaigns are won on this platform, because the auction rewards relevance. A better ad does not just convert more clicks. It wins more auctions at a lower effective cost, a dynamic covered in the pricing guide.

Getting the Creative Done For You

Writing for a new format takes reps. Focal is a ChatGPT Ads agency that drafts, tests, and ships creative for the format daily: hooks, angles, and copy built for conversational placement rather than repurposed from Google or Meta scripts, with competitor research refreshed weekly.

Frequently Asked Questions

What do ChatGPT ads look like?

A single sponsored card below the end of a ChatGPT response: small advertiser logo, title, body text, and a link. Ecommerce brands can also show shoppable product cards with name, price, and image pulled from a connected catalogue. All ads are labelled as sponsored and do not affect ChatGPT's answers.

What are the ChatGPT ad specs?

Headlines around 30 characters (capped at 36), body copy of roughly two sentences and 19 words with at least one specific number, plus a CTA that names the action. Product feed ads pull creative directly from your catalogue feed.

Are there video ads on ChatGPT?

Not in 2026. The current formats are the banner unit in answers and product feed cards. OpenAI has said it plans to expand formats as the pilot grows.

Can I reuse my Meta or Google ad creative on ChatGPT?

The angles can carry over; the execution cannot. Hype hooks, vague superlatives, and exclamation marks underperform next to ChatGPT's calm register. Rewrite winners flat and direct before porting them, and test them as new creative rather than assuming past performance transfers.
