ChatGPT advertising isn’t available yet (as of February 2026), so we can’t compare actual costs. However, we can look at what’s likely when it launches.
Expected Cost Structure
Google Ads (Current):
- Auction-based bidding on keywords
- Average CPC in Australia: $2-$5 for most industries
- Costs vary by competition and Quality Score
ChatGPT Ads (Expected):
- Likely CPM or CPC model
- Predicted to start competitively with search ads
- May cost more initially due to novelty and limited inventory
Things to Consider
Different intent: Google Ads targets searchers with buying intent; ChatGPT ads target users asking questions. The ad format will likely use conversational, AI-generated responses rather than traditional text ads. Attribution will be harder – tracking conversions from AI chat interactions isn’t straightforward. And expect limited early availability, which usually means high demand and higher costs at launch.
Watch Out For
Don’t assume cheaper equals better ROI – conversion rates matter more than cost per click. ChatGPT ads will need different creative and messaging than search ads, so test carefully. Budget cautiously too – new platforms often have unpredictable performance in early stages.
How ROI Can Help
We’re closely monitoring developments in ChatGPT advertising. When it launches, we’ll help Australian businesses test early access with controlled budgets, develop ad strategies that work conversationally, and compare real performance against Google Ads for your industry. Most importantly, we’ll track what actually matters: cost per lead and customer acquisition cost, not just CPC.
