QuestionChatGPTGoogle AIGravity
Where ads appearBelow a ChatGPT response (one ad unit); multi-image ad format being tested during image generation[1]Directly within or alongside AI-generated responses when a search or conversation has commercial relevance, including across follow-up questions in AI Mode.[2]Chat apps, coding assistants and IDEs, consumer AI apps and AI search. Gravity names no specific publisher apps.[3]
Buying modelViews (CPM), Clicks (CPC), Conversions (oCPC or oCPM); never billed per conversion[4]Same auction as Search; CPC or conversion-based bidding; no extra charge to participate.[2]CPM (per 1,000 impressions), or CPA where the account allows it. No click (CPC) billing for new campaigns.[3]
Minimum spendUSD 25 per day (varies by currency, e.g. EUR 15, GBP 15, CAD 25, AUD 25, JPY 2,500, INR 725)[4]Existing Search, Shopping and Performance Max campaigns are automatically eligible; no new campaign or separate budget needed.[2]No minimum; start with any daily budget. A payment method is required before a campaign can launch.[5]
How ads are matchedAd-group descriptions of relevant products, use cases or needs; not exact-match keywords; up to 2,000 per ad group[6]AI Max for Search, broad match, Shopping and Performance Max are eligible for both contextual matching (query + AI response) and direct query matching.[2]Contextual: the engine compares recent conversation messages with active campaigns, runs an auction and returns the winning ad.[7]
Placement controlNo ads near personal health, mental health or politics; ad policies list further excluded contexts[1]Not possible: you can't target only AI Overviews/AI Mode or opt out of them separately from Search.[2]Ads show only on websites and apps Gravity has verified; Gravity reviews each platform before real ads serve.[8]
ReportingImpressions, clicks and CTR about every 15 minutes; spend delayed 7–8 hours; conversions update daily[9]AI Overviews / AI Mode performance is included in aggregate in standard campaign reports; no separate breakout is described.[2]Ad-unit reports give impressions, clicks, spend, CTR, CPC, CPM; conversions, CPA and ROAS are attributed only at campaign level.[10]
Label shown to usersClearly labelled as sponsored and visually separated from the answer[11]"Sponsored"; visually distinguished from organic content.[2]All formats carry a "Sponsored" label.[12]
Countries89 countries (as of 2026-10-21)[13]English only for ads within AI Overviews and AI Mode.[2]Countries chosen at campaign/ad-group level; none selected means all countries. Regions and DMAs via geo_targets.[14]

Google’s minimum-spend row shows that AI placements need no separate campaign or budget. We found no Google page that states a minimum spend or confirms there is none.
