How to test ChatGPT ads, starting from your business listing

ChatGPT now shows labelled ads, and since May 2026 advertisers can buy them through OpenAI’s self-serve Ads Manager. It’s a new channel with few reliable benchmarks, so treat it as a test: small budget, clear tracking, and a fair comparison with what already works.

1. Know what you’re buying

ChatGPT ads are sponsored placements, labelled as ads and kept separate from ChatGPT’s answers. OpenAI opened a beta self-serve Ads Manager at ads.openai.com in May 2026, first with cost-per-impression buying, then cost-per-click and conversion-focused bidding. Availability started with US businesses; check Ads Manager for your country.

2. Claim your business listing first

Claim and complete your profile in Business Hub before you advertise, so people who see your ad and then ask ChatGPT about you get accurate details. The two are connected: eligible US ecommerce and online service businesses can create a Business Agent and sponsor it as the destination for their ads.

3. Pick one offer and one question

Choose the offer you sell best and the question a buyer would ask ChatGPT right before needing it, such as how to fix a problem you solve. The ad should answer that moment, not describe your company.

4. Choose where people land

Send clicks to a landing page that matches the ad word for word, with one clear next step, or to your Business Agent if you’re eligible and it can answer buyers’ questions well.

5. Set up tracking before you spend

Use the conversion tracking Ads Manager offers, add UTM tags so ChatGPT ad visits show up separately in GA4, and make sure every inquiry or sale can be traced back to the ad.

6. Set a test budget you can afford to learn with

Early advertisers report lower click rates than Google search and limited reporting, so pick a fixed amount for two to four weeks. Published minimums and price benchmarks differ between sources, so check the current numbers in Ads Manager rather than relying on blog figures.

7. Compare it fairly

Judge the test on cost per qualified lead or cost per sale, next to your Google or Microsoft Ads results for the same offer. Clicks and impressions alone don’t tell you whether it worked.

8. Scale, adjust or stop

If ChatGPT brings qualified leads at a cost you can live with, raise the budget step by step. If not, change one thing, such as the question, the ad or the landing page, and test again, or put the money back into channels that already pay back.

Practical notes

What I’ve learned and use in practice, checked against current benchmarks and official checklists on 10 November 2026. Experience and benchmarks, not guarantees.

  • Early advertisers report click rates well below Google search and limited reporting: you can’t see the conversations your ads appeared in.
  • Targeting can miss, with ads shown for unrelated topics; one study found about 1 in 7 ads appeared for the wrong topic.
  • Large brands have reported better early results than small advertisers, so keep a first test small and compare it with your other channels.

Before you start

Ads speed up what already works. If people who find you can’t yet understand and buy your offer, or you can’t track an inquiry to a sale, fix that first. The ads readiness check helps you decide.
