ChatGPT Ads and Google Ads capture a different moment in the customer journey. Google Ads is shown for a word typed into the search engine \u2014 a short, transactional signal, with keywords, match types and twenty years of benchmarks. ChatGPT Ads is shown under ChatGPT\u2019s answer by relevance to a conversation in which a person describes their situation in sentences \u2014 targeting is through context hints, not keywords, and OpenAI states that as of September 2026 there are no performance benchmarks by industry. Google charges per click, per conversion or by target return; ChatGPT charges per 1,000 impressions or per click, including in campaigns optimised for conversions. Google is for capturing existing demand with proven volume; ChatGPT is for presence earlier in the decision, with a customer who is still comparing. The point is not replacement but complement: ChatGPT Ads is tested as an additional channel with a small budget, while Google continues to bring the main volume. Below is the comparison point by point.<\/p>\n

I am Hristiyan Panov \u2014 a Performance Marketing consultant with over 5 years of experience and over \u20ac2,000,000 in managed ad budget for more than 90 companies on Google and Meta. Below is a comparison between the two channels based on the official documentation and on what can be verified in my own account.<\/p>\n

What moment of the decision does each channel capture?<\/b><\/h2>\n

A Google search is a signal of an already formulated need: \u201cGedore 108-piece set price”. A ChatGPT conversation is earlier and richer: \u201cI\u2019m repairing my car myself, what tools do I need to replace brake pads and discs?”. The second person has not yet decided what to buy, but has described their situation more precisely than any keyword. OpenAI describes this as presence \u201cwhile people research, compare and decide”. Google captures the end of this process; ChatGPT, the middle of it.<\/p>\n

The practical consequence: an ad in ChatGPT should respond to the comparison the customer is making, not push them towards a purchase. The first advertisers report that ads that answer the question perform better than purely commercial ones, and that landing pages that explain the choice work better than the home page. In detail: how advertising in ChatGPT works<\/a>.<\/p>\n

How is the ad targeted \u2014 keywords versus context hints?<\/b><\/h2>\n

In Google Ads, targeting is by keywords with match types, negative keywords, audiences and signals. In ChatGPT Ads, targeting is by context hints \u2014 descriptions of situations in which the product is useful, set at the ad group level. They are not exact-match keywords and do not guarantee delivery in a specific conversation. There is no \u201csearch terms” report: Ads Manager does not show which conversations triggered the ad. This is a significant difference for anyone used to cleaning up the account through the search terms report. In detail: how to write context hints<\/a>.<\/p>\n

Geographic targeting exists in both places: ChatGPT Ads supports countries and, in the USA, states, DMAs and postal codes; in other countries availability is checked in the location selection when creating the campaign. Personalised ads based on chat history are initially not offered in the European Economic Area.<\/p>\n

How is payment made and what are the budgets?<\/b><\/h2>\n

Google offers payment per click and automatic strategies based on a target cost per conversion or a target return. ChatGPT offers three objectives: Reach, paid per 1,000 impressions; Clicks, paid per click; and Conversions (oCPC), in which the campaign is optimised towards a standard event but payment remains per click. There is no payment per conversion and no target return. OpenAI recommends an initial maximum bid of 3\u20135 USD per click for CPC campaigns.<\/p>\n

The minimum daily budget in ChatGPT Ads depends on the account currency and is not currently published in euros. For a meaningful first test I recommend an advertising budget of \u20ac600 to \u20ac1,000 for 30 days, while the main budget stays in Google. Breakdown: how much advertising in ChatGPT costs<\/a> and how much Google advertising costs<\/a>.<\/p>\n

What are the formats and how much production do they require?<\/b><\/h2>\n

Google Search works with responsive text ads with up to 15 headlines and 4 descriptions; Performance Max and Shopping add visuals, video and a product feed. ChatGPT Ads has one format: name and logo, headline (16\u201324 characters recommended, 50 maximum), description (32\u201348 characters, 100 maximum), a square visual up to 1200\u00d71200 px and a landing page. For online shops there are also product feed campaigns, which show a product, price and brand; OpenAI states that they are among the strongest in the programme so far.<\/p>\n

Production in ChatGPT is lighter, but the requirement for variety is higher: OpenAI recommends many different headline and description variants for each offer, not cosmetic reworkings of one text. The value shifts from the visuals to the structure of intents.<\/p>\n

How is the result measured?<\/b><\/h2>\n

Google Ads has a mature ecosystem: conversions, Enhanced Conversions, offline import, Consent Mode and a link with GA4. ChatGPT Ads offers the OpenAI Pixel, the Conversions API with deduplication by event ID, the oppref click reference, automatic advanced matching and a report with conversions, revenue and ROAS by the order_created event. Conversions enter the report with a 24\u201348 hour delay, and the view-through window is fixed at one day. UTM parameters work in both places.<\/p>\n

The practical difference is in the order of checking. With Google, you reconcile the conversion in the account and in GA4. With ChatGPT, you reconcile the pixel, the Conversions API and the order in the shop.<\/p>\n
