ChatGPT crossed 500 million weekly active users faster than any consumer product in history. OpenAI's decision to monetise that attention through advertising is the most significant new paid media channel since Instagram opened its API. If you're a performance advertiser and you're not in early, you're going to be playing catch-up.

This guide covers everything you need to go from zero to live campaign. We'll cover the access process, how the platform differs from Google and Meta, and the setup decisions that will determine whether your first campaigns succeed.

Getting access to ChatGPT Ads

As of mid-2026, ChatGPT Ads is in a controlled rollout. Access is granted through an application process, not self-serve signup. Here's how to get in:

1. Apply through OpenAI's advertiser portal. You'll need a business email, a description of your product or service, and estimated monthly ad budget.
2. Expect a review period of 2–4 weeks. OpenAI is prioritising brands with clear product-market fit and sufficient budget (the informal minimum appears to be $5,000/month).
3. Prepare your website for scrutiny. OpenAI reviews landing page quality as part of ad approval, similar to Google's Quality Score system.

Campaign structure and objectives

ChatGPT Ads follows a familiar hierarchy: Account → Campaign → Ad Group → Ad. If you've run Google or Meta campaigns, the structure will feel intuitive. The key differences are in how objectives map to delivery.

Available campaign objectives

• Conversions — optimise toward a defined conversion event on your website
• Traffic — maximise clicks to a destination URL
• Awareness — maximise impressions within your target audience
• Lead Generation — collect leads via native forms within the ChatGPT interface

How targeting works

ChatGPT Ads targeting is fundamentally different from Google and Meta. There's no keyword bidding and no interest graph. Instead, OpenAI uses conversational context signals — the topics, questions, and intent patterns of the current and recent sessions.

What this means practically: your ad shows when someone is in a conversation that's topically relevant to your product. A user researching SaaS tools for project management is a signal. A user asking about investment returns is a signal. OpenAI matches your campaign to those signals based on your category and creative content.

Targeting options available

• Topic categories — broad content verticals (Finance, Technology, Health, etc.)
• Audience segments — first-party and modelled segments from OpenAI's user data
• Retargeting — pixel-based custom audiences from your website (requires CAPI setup)
• Lookalike audiences — modelled from your existing converters
• Geographic targeting — country, region, and metro-level

Creative formats and best practices

ChatGPT Ads supports three primary ad formats as of mid-2026:

1. Sponsored responses

Text-based placements that appear within or adjacent to ChatGPT's answer. These are the highest-intent format — the user is actively engaged with content related to your category. Copy should be conversational, informative, and directly relevant to the topic context.

2. Inline display units

Image-based placements that appear between responses or at the bottom of a conversation. Standard display creative applies here — clear headline, single visual, strong CTA.

3. Recommended links

Native link placements that appear as "suggested resources" within responses. These require OpenAI editorial approval and are typically reserved for higher-spend advertisers.

Conversion tracking setup

Accurate conversion tracking is non-negotiable on ChatGPT Ads. The platform's bidding algorithm optimises toward the conversion events you define — garbage data in means wasted budget out.

Step 1: Install the OpenAI pixel

Add the base pixel code to every page of your website via GTM or direct installation. Verify it's firing correctly using the OpenAI Pixel Helper browser extension.

Step 2: Define conversion events

Set up standard events (Purchase, Lead, Sign Up) and any custom events specific to your funnel. Assign realistic values to purchase events — the algorithm uses these for value-based bidding.

Step 3: Implement the Conversions API

Browser-based tracking alone is insufficient in 2026. Server-side event passing via the Conversions API ensures you're capturing the conversions that browser signal loss misses. See our full CAPI setup guide for the technical walkthrough.
