First-party OpenAI sources only.

At a glance

The essentials in one minute.

  1. 01

    Who sees ads

    Ads may appear on the Free and Go plans. Plus, Pro, Business, Enterprise and Edu accounts are ad-free. OpenAI does not show ads to accounts identified as belonging to people under 18.

    Documented by OpenAI
  2. 02

    Where ads appear

    Ads are clearly labelled and shown separately from ChatGPT's answer. OpenAI currently documents the standard ad unit below the response.

    How campaigns are bought

    Ads Manager supports Views, Clicks and Conversions objectives, with billing based on impressions or valid clicks depending on the campaign setup.

    Documented by OpenAI
  4. 04

    How relevance works

    The current conversation can inform relevance. Advertisers can also use supported campaign controls and context hints, but context hints are not exact-match keywords or delivery rules.

  5. 05

    How conversions are measured

    Advertisers can send conversion events with the OpenAI Pixel, the Conversions API, or both.

01What ChatGPT Ads are

Paid placements inside a conversational experience.

ChatGPT Ads lets advertisers appear while people explore options, compare alternatives and make decisions in ChatGPT.

The standard ad unit documented by OpenAI includes the advertiser name, brand icon, headline, description, landing page and creative image.

That does not mean an advertiser buys its way into ChatGPT's recommendation. The paid placement and the model's answer are separate.

02Who can see ads

Reach starts with the plan a person uses.

Documented by OpenAI

OpenAI currently says ads may appear on Free and Go. Plus, Pro, Business, Enterprise and Edu accounts are ad-free. Ads are not shown to accounts identified as belonging to people under 18.

03Ads and answers

Paying for an ad does not buy influence over the answer.

Documented by OpenAI

OpenAI describes answer independence as a core advertising principle. Ads run separately from the chat model, are clearly labelled and do not influence the answer ChatGPT gives.

Advertisers cannot shape, rank or alter ChatGPT's response by buying advertising.

You are buying a paid placement, not the answer.

04Availability and advertiser eligibility

Access depends on the advertising entity, market and policy.

Availability may vary

OpenAI announced self-service Ads Manager access across 31 European markets from 31 August 2026.

For self-service access, the legal entity that advertises and is billed must be based in a country OpenAI currently lists as available.

Country availability is only one gate. The advertiser, creative, landing page and promoted category must also comply with the current advertising policies and review requirements.

Availability can change. Check the live OpenAI country and policy pages before planning a campaign.

05Campaign structure and buying

Campaign → Ad group → Ad.

Documented by OpenAI

Ads Manager uses a familiar hierarchy, but the conversational environment changes how relevance is described.

  1. Campaign

    Defines the objective, budget, dates and supported targeting controls.

  2. Ad group

    Groups ads around a product, service, theme or customer need and can carry context hints.

  3. Ad

    The creative unit shown to the user: brand, headline, copy, landing page and image.

Current campaign objectives

  1. 01Views

    Designed for visibility. Billing is based on impressions, expressed as CPM.

  2. 02Clicks

    Designed to drive traffic. Billing is based on valid clicks, expressed as CPC.

  3. 03Conversions

    Designed to optimise towards a supported conversion event. Depending on the campaign setup, billing can be based on valid clicks or impressions. You do not pay per conversion.

06Relevance and targeting

Context matters, but context hints are not keywords.

Availability may vary

OpenAI says ad selection considers expected relevance and outcomes. Signals can include the current conversation's context and intent, the landing page, headline and copy, advertiser-provided context hints and supported targeting controls.

When a user has ad personalisation enabled, selected signals from their broader ChatGPT experience may also be used inside OpenAI's system to assess relevance.

Context hints

Context hints are advertiser-provided descriptions of what an offering is, who it may help and when it may be useful. They inform relevance.

They are not exact-match keywords, targeting rules or a guarantee that an ad will appear in a specific conversation.

Explicit campaign controls

Ads Manager also supports campaign-level controls such as country and, where available, platform and custom-audience settings. Availability can depend on the account or campaign type.

07Conversion measurement

The ad click is only the beginning of the measurement problem.

Documented by OpenAI

Ads Manager can measure actions after an ad click, including events such as a purchase, lead or registration.

Advertisers can send those events using the OpenAI Pixel, the Conversions API, or both.

  • OpenAI Pixel

    Browser-side measurement that can capture the OpenAI click reference and send eligible conversion events.

  • Conversions API

    Server-side conversion events sent from the advertiser's systems.

  • Using both

    When the same conversion is sent through both methods, OpenAI instructs advertisers to use the same event ID so the event can be deduplicated.

The click reference
OpenAI calls its click reference oppref. It can be appended to the landing-page URL and associated with later conversion events.
Why numbers can differ
OpenAI notes that Ads Manager, analytics platforms and other ad systems can report different conversion totals because attribution methods, windows, timestamps, consent, storage conditions, deduplication and modelled measurement can differ.

08What advertisers can and cannot see

Relevance does not mean access to private conversations.

Documented by OpenAI

OpenAI may use information inside ChatGPT to determine which ads are relevant. That information is not handed to the advertiser as a private conversation.

OpenAI says advertisers do not receive a person's private chats, chat history, memories, name, email, precise location, IP address or sensitive information through ordinary advertising reporting.

Advertisers receive aggregated performance information and the measurement signals created through their own advertising and conversion setup.

The system can use context without giving the advertiser the conversation.

09Attribution

Platform attribution is useful. It is not the same as business truth.

Impossible Solutions interpretation

Ads Manager answers an important question: what activity does OpenAI attribute to the campaign under its measurement rules?

That is necessary for optimisation. But it is a different question from whether the same revenue can be verified in the advertiser's own systems, and different again from whether the advertising caused an outcome that would not otherwise have happened.

That is why we keep three ideas separate

  1. 01

    Platform-attributed

    What the advertising platform credits to the campaign.

  2. 02

    Business-verified

    What the advertiser can also verify in its own commercial systems.

  3. 03

    Incrementality-estimated

    An estimate of what probably would not have happened without the advertising.

They answer different questions. They should not be presented as one number.

10Recent platform developments

ChatGPT Ads is moving quickly.

Two examples show how quickly the platform is expanding beyond the first ad format.

  • Sponsored Agents

    OpenAI is testing Sponsored Agents, which let a person open a conversation with an AI representative of a business from an ad. The format is currently limited to selected advertisers in an alpha test.

    Availability may vary

  • HubSpot integration

    OpenAI now documents a HubSpot integration that can connect a ChatGPT Ads account, create campaigns, capture leads and review performance. OpenAI says it is available to HubSpot customers wherever ChatGPT Ads is available, subject to the required account permissions.

    Availability may vary

These developments are examples of platform evolution, not capabilities we promise as part of an Impossible Solutions engagement.

11What is still moving

Treat current capability as dated information, not permanent platform law.

ChatGPT Ads is developing quickly. Country availability, category eligibility, formats, optimisation options, integrations and account-level capabilities can change.

  • Check self-service availability for the advertiser's legal entity.
  • Check current advertising-policy eligibility for the category and destination.
  • Check which objectives and measurement capabilities are enabled for the account.
  • Reconfirm new formats and integrations before building them into a plan.

We re-check moving platform facts before each engagement rather than treating an old screenshot or help article as permanent truth.
