ChatGPT now has ads. If you're running campaigns on Google and Meta, you've heard about OpenAI's Ads Manager. The question: is it worth testing? The short answer: yes, but only with an agency understanding the platform's mechanics, not one treating "AI marketing" as a service.
Every ranking page for this keyword is self-promotional or a global list without buyer guidance. None explains what a partner actually does, how to verify their credentials, or what realistic outcomes look like in 90 days. This guide fills that gap.
A ChatGPT Ads agency partner operates inside OpenAI's Ads Manager on your behalf. Unlike Google Search or Meta agencies, they don't manage keyword lists or audience segments. The entire targeting model differs, which is where most agencies stumble.
Context hints are natural-language descriptions of conversation types on ChatGPT. Instead of typing "enterprise software," you write "developers comparing Python deployment tools" or "finance managers evaluating cloud solutions." Hint quality drives targeting precision. A strong partner audits your Google Search queries and translates high-intent keywords into conversational context.
They also manage ad creative under tight character limits, bid strategy within a second-price auction where context quality matters more than bid alone, and measurement setup via OpenAI's conversion pixel and Conversions API. Each requires platform-specific knowledge. This resembles how managing programmatic buys on DV360 differs from search or social.
OpenAI's Ads Manager mirrors other platforms: Campaign, Ad Group, Ad. But mechanics differ. Ads appear only for Free and Go tier users; paid tiers stay ad-free. This constrains addressable audience.
You buy on CPM (impressions) for awareness or CPC (clicks) for direct response. A relevance-weighted auction determines placement. Bid amount alone doesn't guarantee position. Instead, OpenAI weights context hint quality, ad relevance, and your bid together. A well-written hint with a lower bid often beats a high bid with weak targeting.
Measurement today is early-stage. You get impressions, clicks, spend, CTR, average CPC, average CPM, and conversions if you set up the pixel or Conversions API. Third-party integration is limited. Attribution beyond last-click is immature. The platform is in beta expansion. Measurement tooling is also new. Any agency promising definitive revenue ROI in month one hasn't run real campaigns here.
Three criteria separate genuine expertise from repackaged PPC skills.
First: documented Ads Manager experience. Ask for case studies or anonymized campaign data. Avoid "We specialize in AI marketing" without specifics. Ask these questions: "How many live campaigns inside OpenAI Ads Manager?" and "Can you share performance data like CTR, CPC, and conversion metrics?" Agencies with real experience give specifics. Those without pivot to generic AI positioning.
Second: defined context hint methodology. Context hints aren't recycled Google or Meta ad copy. Strong partners have a documented process. They audit your Google Search data, identify high-intent queries, translate to conversational intents, write hints matching those intents, and test variations. If an agency can't explain their process or suggests "ChatGPT will generate them," that's a red flag.
Third: measurement framework grounded in platform reality. A credible partner sets proxy metrics for 90 days: CTR, average CPC, and assisted conversions from Conversions API. They benchmark against your Google Search performance and agree on what "good" looks like before scaling. Partners promising revenue attribution or ROAS in 30 days lack real platform experience.
A well-designed engagement has clear structure and decision gates.
Phase 1: Setup (weeks 1 to 2). The agency audits your Google Search campaigns to find high-intent keywords. They translate these into ChatGPT context hints based on how your audience talks on the platform. They set up the conversion pixel or Conversions API and configure reporting.
Phase 2: Pilot campaign (weeks 3 to 12). You commit 5-10% of your existing paid media budget to run 2 to 3 test campaigns. The agency continuously optimizes context hints, tests creative, and monitors metrics weekly. They document performance against your baseline.
Phase 3: Evaluation (end of week 12). The agency presents results. How did proxy metrics perform? Did conversions justify spend? How does this fit your multi-channel mix? You decide: scale, reallocate, or pause. A strong partner recommends the honest path. As a certified partner managing enterprise campaigns, we understand this process.
This is where agencies oversell and brands get disappointed. Here's the honest baseline.
CTR: Expect 3 to 7% depending on industry, creative quality, and hint relevance. This is higher than display but lower than Google Search. B2B software runs higher. Brand awareness runs lower.
CPC: Expect 15 to 40% higher than your Google Search average. This reflects the channel's early stage and smaller advertiser base.
Assisted conversions: This matters most but measures hardest. If you integrated Conversions API correctly, you see who clicked, visited your site, and converted. Expect 2 to 8% of clicks converting in 90 days. This is a proxy metric showing engagement, not revenue attribution.
Red flags: If CPC is 2 to 3 times higher than Google with no uplift in conversions, the channel may not fit your funnel. If hints generate 0.5% CTR consistently, they need rewriting. If the agency can't show weekly breakdowns, they're not transparent.
A context hint describes a conversation type on ChatGPT. Instead of "DevOps," you write "engineering teams comparing container platforms." Keywords are single search terms. Hints are conversational patterns. Copying Google ads into ChatGPT almost never works because the targeting model is fundamentally different.
Ask for three things: anonymized campaign performance data, a documented hint-writing process, and client references running live campaigns. If they can't provide two of these, they lack real experience. "We took an AI marketing course" differs from "We've managed significant live spend."
As of mid-2026, OpenAI Ads Manager is available in the US, UK, Canada, Australia, New Zealand, Japan, and Korea. India is not yet supported. However, Indian brands can reach Indian users in supported markets by running campaigns from an OpenAI account with a supported payment method.
OpenAI named Dentsu, Omnicom, Publicis, and WPP as launch agency partners in May 2026. These are holding-company partnerships likely including early feature access and support. But a self-serve Ads Manager account accesses the same platform. An independent agency with real experience often delivers better results than a holding company treating ChatGPT as one bundled line item.
Industry benchmarks suggest approximately USD 5,000 per month. This allows volume to optimize hints, test creative, and gather significant conversion data. Smaller budgets make conclusions unreliable. Position this as 5-10% of existing paid media spend, not a reallocation from proven channels.
OpenAI offers two options: a browser-based conversion pixel (simpler but less reliable) or a server-side Conversions API (more accurate but requires technical setup). For B2B brands with CRM systems, the Conversions API is better. You pass CRM event data directly to OpenAI for better targeting.
Ask these five: (1) Walk me through your context hint writing process. (2) Show me anonymized performance data from my vertical. (3) How do you measure success on a platform with immature attribution? (4) What are realistic proxy metrics for 90 days? (5) If this underperforms Google Ads, when do we pause? Strong partners answer directly and honestly, especially the last question.
Yes. OpenAI's Ads Manager is self-serve and access has expanded since beta. The learning curve is shallow if you know Google Ads Manager or Meta Business Suite. The main risk is writing ineffective hints. Most first attempts need iteration. An agency accelerates performance. Choose based on your team's bandwidth.
