Now that you can advertise inside ChatGPT, the obvious question is whether it competes with Google Ads. The short version: it does not replace search, it opens a new surface. The two reach people at different moments, with different targeting and different maturity. This guide compares them honestly so you can decide where your budget works hardest.
The short answer
Google Ads captures demand that already exists: someone is searching for what you sell, and you show up. ChatGPT Ads capture demand as it forms: someone is reasoning through a decision with AI, and you appear beside that thinking. For most Australian businesses the answer is not one or the other, it is both, with a larger, proven budget on Google and a focused early-mover test on ChatGPT.
How each platform works
Google Ads is a mature network. You bid on keywords and audiences and run ads across Search, Shopping, Display, YouTube and Gmail, with a deep toolkit for targeting, formats and measurement. It is the default for paid acquisition because the demand and the data are both enormous.
ChatGPT Ads, run through OpenAI's Ads Manager (currently in beta), place ads below relevant ChatGPT conversations. The ad carries your name, logo, a title, copy, an image and a landing page. OpenAI does not show ads to Plus, Pro or Business users, or to anyone it predicts is under 18, so the audience is signed-out and free-tier users aged 18 and over.

Targeting: context vs keywords
This is the biggest difference. Google Ads targets by keywords, audiences and demographics that you choose, structure and bid against. ChatGPT Ads is contextual: OpenAI selects ads based on how relevant they are to the context and intent of the conversation. You guide it with context hints at the ad-group level, which describe the conversations where you are relevant, but they are not exact-match keywords and do not guarantee delivery. In practice, Google rewards precise keyword and audience structure, while ChatGPT rewards describing real buying moments well.
Intent and the moment captured
A search query tells you what someone typed. A conversation tells you what they are working through. Google Ads excel at the bottom of the funnel, the moment of active search. ChatGPT Ads sit earlier and wider, in the exploring-and-comparing stage where people increasingly turn to AI to weigh options. Neither moment is more valuable in the abstract; the right balance depends on whether your buyers research first or search to buy.
Cost and buying models
Google Ads sells clicks, impressions and conversions across formats, with costs set by auction and shaped heavily by how competitive your keywords are. ChatGPT Ads offer two models: pay per 1,000 impressions (CPM) for Reach, or pay per valid click (CPC) for Clicks, settled through a relevance-weighted, second-price auction. OpenAI suggests starting CPC bids around 3 to 5 US dollars, and there is no published minimum spend. The headline today is competition: ChatGPT Ads are new, so there is far less of it, which is part of the early-mover appeal.

When to use each, and when to use both
Lead with Google Ads when you have clear, existing search demand and need leads or sales now. Add ChatGPT Ads when your customers research and compare before buying, when you want to build presence in AI-assisted decisions, or simply to claim ground while competitors hesitate. For most growing businesses the honest answer is both: keep your proven Google spend working, and run a focused ChatGPT Ads test alongside it, measuring each so budget follows performance.
Getting started with either, or both
You can run both yourself, but they reward different skills, and ChatGPT Ads is a brand-new platform. We manage both side by side: our ChatGPT Ads management and Google Ads campaign management services share one team and one set of conversion tracking, so you see clearly which channel earns each lead and we move budget toward whatever works.
Whichever channel wins your budget, the AI assistant itself can do real work inside your Google Ads account. See how to use ChatGPT for Google Ads.
