Since 31 August 2026, anyone with a Spanish company and a credit card can open OpenAI’s Ads Manager and buy ads inside ChatGPT. No sales team, no agency partner, no minimum spend. Self-service went live across 31 European markets at once — Spain, Germany, France, Italy, the Netherlands, the Nordics — six months after the US pilot started in February.
I have spent the last two weeks reading the actual documentation rather than the hot takes, and the honest summary is this: ChatGPT Ads is a real channel with real measurement plumbing, and it is also a channel where most of the people who see your ad are on the free tier, in a conversation you cannot see, being matched by a system you cannot audit. Both things are true. The question for a Spanish B2B SaaS or a D2C brand is not «is this the future», it is «what would a €1,500 test have to prove before I put it in the media plan».
This is how I would set that test up, what I would instrument first, and where I expect it to overlap with the Google Search budget you already run.
What actually went live in Spain on 31 August — and what did not
OpenAI’s timeline, from its own announcements: US test on 9 February 2026, logged-in adults on the Free and Go tiers only. Canada, Australia and New Zealand in spring. UK, Mexico, Brazil, Japan and South Korea on 11 August. Then the European announcement on 18 August, with self-serve access through Ads Manager confirmed on 31 August. On 31 August OpenAI also reported the platform had passed a $1 billion annualised run rate in under 200 days — which tells you the US advertisers who got in early did not leave.
What you get in the account today, per the developer docs and the September product email: CPM and CPC bidding plus a conversion-optimised objective; geo-targeting and custom audiences built from hashed emails, phones or mobile ad IDs; a JavaScript measurement pixel, a no-JS image tag and a server-side Conversions API; product-feed campaigns for retailers, which serve in a multi-product carousel; total-budget pacing; and — new on 4 September — an Ads Manager plugin that lets you build and edit campaigns from inside ChatGPT itself.
What you do not get: any view of the conversation your ad appeared in. Advertisers receive aggregate views and clicks, nothing else. That is a deliberate design choice, stated in every OpenAI ads document since February, and it is the single biggest difference between this and a search-terms report.
Who actually sees a ChatGPT ad, and why it changes your forecast
Ads are only shown to users on the Free and Go plans. Plus, Pro, Business, Enterprise and Education accounts never see them, and Free users can opt out of ads in exchange for fewer daily messages. Ads are not served to anyone under 18 or predicted to be, and they are not eligible near health, mental health or political topics.
Read that as a media planner and three things follow. First, the audience skews away from the people who pay for software — the CFO of a mid-market company evaluating a finance tool is more likely on a Business seat than on Free. Second, the exclusions are broad enough that entire categories (supplements with any health claim, for instance) will find inventory thin or unpredictable. Third, ad selection is driven by the topic of the current conversation, the user’s past chats and their past ad interactions. Your ad appears when someone is talking about your category, which is a stronger intent signal than a display impression and a weaker one than a typed search with commercial modifiers.
So the right mental model is not «Google Search but in ChatGPT». It is closer to an intent-matched mid-funnel placement with a free-tier skew. That is not a criticism; it is what you should be pricing when you set a target CPA for the test.
How to instrument it before you spend a euro
Every failed channel test I have seen failed at measurement, not at the channel. ChatGPT Ads gives you three tracking paths that all report to one Pixel ID, and the order you set them up in matters.
| Before launch | Why it matters |
|---|---|
| Measurement Pixel via GTM with the standard events you already fire for Meta and Google | Conversion-optimised bidding needs a conversion signal. Launch on CPC without the pixel and you have a traffic campaign, not a test. |
| Conversions API from the backend (or via your HubSpot / Shopify server events) with hashed email and phone | Browser-side matching alone will under-report, exactly as it does on Meta. September added more matching fields (name, region, postal code, GAID); use them. |
A dedicated UTM source (utm_source=chatgpt&utm_medium=paid) and a custom channel group in GA4 |
Without it, ChatGPT traffic lands in Referral or Unassigned and you will never see it against the rest of the mix. |
| A landing page that answers the conversation, not the keyword | The user arrives mid-comparison. A page that opens with «why choose us over X» outperforms a generic homepage every time. |
| A holdout in the CRM: a flag on every ChatGPT-sourced contact | Platform-reported conversions will not tell you whether the leads closed. Your pipeline report will, eight weeks later. |
One more thing the docs are explicit about: a view-through conversion model is «coming soon», billed on impressions and optimised on both clicks and views. When it arrives, keep it out of the test. A first test needs a clean click-based read; view-through attribution is where new channels go to look better than they are.
A €1,500 test that proves something: B2B SaaS versus D2C
The two kinds of clients I run paid media for need different tests, because the channel treats them differently.
For a B2B SaaS — say a finance-automation tool selling to founders and CFOs — the honest hypothesis is not «ChatGPT will produce demos at a lower CPA than Google». It is «people who ask ChatGPT how to structure their company’s cash-flow reporting are in our ICP, and we can reach them before they type a branded search». So: one campaign, conversion-optimised toward a soft conversion (guide download or pricing page view, not demo booked), custom audience exclusion built from current customers, geo Spain plus your two best EU markets, three ads that each answer one specific question. Success at €1,500 is not a demo. It is a cost per qualified contact within 1.5× of your LinkedIn Ads number and a CRM flag you can follow for two months.
For a D2C brand — a daily nutritional beverage, a coffee subscription — the channel is closer to Shopping than to Search, and the product feed is not optional: since early September, product-level results in ChatGPT come from brands that submit a feed, and feed campaigns serve in the carousel unit with per-card impression and click reporting. The test is a feed campaign on conversion optimisation with the Pixel plus Shopify server events, a custom audience of past purchasers for exclusion, and a hard rule on claims: anything that reads as a health benefit risks being ineligible near health topics, so lead with taste, ritual and convenience. Success is a blended ROAS you would accept from a Meta prospecting campaign, on a channel where the comparison is happening in the chat instead of on your PDP.
Where it cannibalises Google Search, and where it does not
The uncomfortable part of any new channel is that it rarely brings new demand; it usually moves existing demand somewhere you now have to pay for. Two checks tell you which is happening here.
Watch branded search volume. If ChatGPT exposures push people to Google your brand, your Search campaign gets the conversion and ChatGPT looks like it did nothing. The ChatGPT-sourced CRM flag plus a look at brand impressions in the two weeks after launch will catch this. It is the same pattern we described when Smart Bidding started absorbing cross-channel signals: the platform that closes claims the credit.
Watch the non-brand long tail. Search queries have been getting longer for eighteen months, and the people typing five-word questions into Google are the same people asking ChatGPT. If your Google non-brand conversions dip in the test geo while ChatGPT-sourced contacts appear, you are paying twice for the same person. That is not a reason to stop; it is a reason to set the ChatGPT target CPA at what a Google long-tail conversion costs you, not at what a display click costs.
And a caveat on the organic side: paid presence in ChatGPT does nothing for whether ChatGPT cites you in an answer. Ads are labelled, separated, and do not influence responses. If being cited is the goal, that is a content and structure problem — the same one Google AI Mode created — and the ad budget will not buy it.
Questions I keep getting asked
Can a company in Spain advertise on ChatGPT right now?
Yes. Self-service access through OpenAI’s Ads Manager has been live in Spain and 30 other European markets since 31 August 2026. You sign up at ads.openai.com; there is no agency requirement and no published minimum spend.
Who sees ads in ChatGPT?
Only logged-in adult users on the Free and Go plans. Plus, Pro, Business, Enterprise and Education users never see ads. Ads are not shown near health, mental health or political topics, and Free users can opt out in exchange for fewer daily messages.
How is a ChatGPT ad targeted?
Ads are matched to the topic of the current conversation, the user’s past chats and their past ad interactions. Advertisers can add geo-targeting and custom audiences (hashed email, phone, mobile ad IDs), but never see the conversation itself — only aggregate views and clicks.
Do ChatGPT Ads help my brand get cited in ChatGPT answers?
No. OpenAI states that ads do not influence answers and are always labelled and visually separated. Being cited organically depends on your content, structure and authority, not on ad spend.
Test it like a channel, not like a headline
The temptation with anything that has «ChatGPT» in the name is to either dismiss it or to announce it. Neither is a media decision. The platform has shipped the pieces a serious advertiser needs — conversion bidding, server-side measurement, audience matching, feed support, an API — faster than any ad network I can remember. It has also, by design, given you less visibility into why an ad served than any channel you currently buy.
So run it the way you would run any unproven placement: instrument first, cap the budget, define the success metric before launch, flag every contact in the CRM, and read the result against your Google long-tail and your LinkedIn or Meta prospecting numbers rather than against zero. If it earns a line in the 2027 plan on those terms, it earned it. If it does not, you have spent €1,500 to know something most of your competitors are still guessing about.
Want the test run properly?
I set up ChatGPT Ads pilots end to end for B2B SaaS and D2C brands in Spain: account and Pixel/CAPI instrumentation, UTM and GA4 channel setup, audience exclusions, three-ad creative brief, CRM flagging, and a written read-out at the end of the budget that tells you whether to scale or stop.
