Short Answer
OpenAI now documents both CPC and CPM buying for ChatGPT Ads. For PPC teams, the important change is not just the bid type. It is that conversational relevance, landing page clarity, and creative specificity become part of the economic equation.
From CPM Reach to CPC Traffic
OpenAI says advertisers can choose a Reach objective for CPM buying or a Clicks objective for CPC buying. That makes ChatGPT Ads easier to compare with search and paid social testing frameworks.
The current advertiser-facing guidance recommends a starting max CPC bid of $3-5 USD per click and lists a $60 CPM default max bid for CPM campaigns. Treat these as beta starting points, not permanent market benchmarks.
How the Auction Is Different
ChatGPT Ads uses a relevance-weighted, second-price auction. In practical terms, the highest bid alone should not be the whole strategy. Clear context hints, accurate ad titles, useful copy, and aligned landing pages can affect eligibility and relevance.
A PPC manager should evaluate ChatGPT clicks against search-quality traffic, not against low-intent social browsing alone. The channel is closer to research and comparison than casual interruption.
Budgeting for an Early Test
The Help Center FAQ says there are not yet stable cross-industry performance benchmarks. Start with a focused test budget, separate campaigns by objective, and give each campaign enough delivery room to produce meaningful impressions, clicks, CTR, average CPC, average CPM, and conversion data.
Do not anchor the plan on older industry rumors about large minimum commitments. The current Ads Manager guidance centers campaign budgets, billing setup, and beta eligibility rather than a universal public minimum spend.
Beta Caveat
ChatGPT Ads and Ads Manager Beta are evolving. Validate pricing, eligibility, formats, measurement, and launch requirements against OpenAI Help Center documentation before committing budget.
