Every week someone asks me the same thing: “Should I put money into ChatGPT Ads or wait?” Forums and marketer groups are split: some call it the next Google, others say they threw money away. The truth sits in the middle, and it depends a lot on your business.
I’m Alonso Jiménez, a Retail Media account director. I manage campaigns on Amazon, Walmart, Target, Instacart and Mercado Libre every day, for brands in the US, Mexico and Latin America. Here’s my no-fluff take: what works, what doesn’t yet, what the public data says, and a quick quiz to tell whether you should test it today.
⚡ THE ESSENTIALS IN 20 SECONDS
- ChatGPT Ads is worth testing if you measure properly, your product gets researched before purchase and your margin can carry $3–5 clicks.
- It’s not worth it without a pixel, with a poorly converting site, or if you expect Amazon Sponsored Products performance.
- Prices dropped fast and measurement improved, but advertisers still want proof of return.

My short verdict: yes, as a controlled test
Are ChatGPT Ads worth it?: worth it as a test channel for brands that can measure conversions and whose customers research before buying. Not yet a channel for your main sales budget.
My stance is the same one I had with TikTok Ads or Amazon DSP when they launched: whoever tests early and measures well learns cheaper. But testing isn’t scaling. It belongs in your experiments budget, not your sales budget.
What works (the real advantages)
People tell ChatGPT their whole problem. You reach a question, not a single word.
100,000+ advertisers have tried it, but many categories are still wide open, especially in Latin America.
Self-serve manager, CPC, pixel, Conversions API, catalogs and custom audiences.
From $25 a day per campaign, without the pilot’s six-figure minimum.
89 countries, including Mexico and most of Latin America.
Criteo and Pacvue are technology partners, so it can plug into your retail media stack.
What doesn’t yet (the honest drawbacks)
- Low CTR. During the pilot, Adthena measured 0.91% vs 6.4% on Google Search.
- Young measurement. Pixel and API only exist since May 2026, and many advertisers haven’t set them up right.
- Less control. No keywords, and OpenAI decides whether to show one product or a carousel.
- Only part of the user base. Free and Go users see ads; Plus, Pro and business plans don’t.
- Flexible daily budget. A single day can spend double your setting.
What the data and advertisers say
| Data point | Source |
|---|---|
| CPM fell from $60 at launch to $25 in some categories within about nine weeks. | Digiday |
| 100,000+ advertisers have run campaigns; available in 89 countries. | OpenAI, Oct 21, 2026 |
| Many advertisers want stronger measurement before raising budgets. | AdExchanger |
| Criteo reported AI-referred conversion rates approaching twice traditional search in some retail categories. | PPC Land, citing Criteo |
| Walmart saw in-chat checkout convert three times worse than sending users to its site. | March 2026 reports |
My read: ChatGPT traffic looks like good quality when it lands on the right page, but it takes volume and measurement to prove it. Be wary of anyone promising a fixed ROAS on ChatGPT Ads at this stage.
Who it’s for and who it isn’t
| Should test | Better wait |
|---|---|
| Brands with considered products (beauty, tech, home, supplements). | Impulse or very low-price products. |
| Ecommerce with a clean feed and a pixel installed. | Stores with no measurement or analytics. |
| High-ticket services (B2B, education, finance). | Businesses with razor-thin margins. |
| Brands that already win on Amazon and want to get in earlier. | Brands still struggling to control ACOS on marketplaces. |
Quiz: should you test ChatGPT Ads today?
Answer five questions and I’ll tell you what I’d do in your shoes.
Agency secrets before you decide
What I tell clients when they ask if they should get into ChatGPT Ads.
Decide on day one: “in 14 days, if CPA isn’t below twice Google’s, I pause.” Without a date, tests turn into fixed costs.
Fund it from experiments, not from Amazon. Don’t starve what already sells.
Track branded searches on Amazon and Google during the test. ChatGPT may influence a purchase that closes elsewhere.
February’s numbers no longer apply. Look for data from the last 60 days.
Before paying, see what ChatGPT says about your category. If it already recommends you, content may matter more than ads.
New channels reward people who measure and punish people who get excited. What has worked for me: enter early with a little, learn fast, and scale only when the numbers ask for it.
Conclusion: test it with a method, not with faith
ChatGPT Ads is worth testing if you have the basics: measurement, a good landing page and margin for a pricey click. If not, fix that first; it pays off on every channel. To start right, follow the series: launching your first campaign, how much it costs and ChatGPT Ads for ecommerce.

Frequently asked questions
Are ChatGPT Ads worth investing in?
Worth it as a controlled test if you can measure conversions and your product is researched before purchase. Not yet a channel for your main budget.
Do ChatGPT Ads work in Mexico and Latin America?
Yes. ChatGPT Ads has been available in Mexico since August 2026 and expanded to 14 more Latin American countries in October 2026.
Is ChatGPT Ads better than Google Ads?
Today Google has more volume and a higher CTR; ChatGPT has less competition and richer conversations. Compare CPA on both with your own data.
How much should I invest to know if it works?
Enough to read conversions: at a $4 CPC, about 300 clicks would be $1,200. Run your numbers in the calculator in my pricing guide.
Do ads influence ChatGPT’s answers?
According to OpenAI, no. Ads are separate, labeled and don’t change the answer.
