Quick Answer
Use Google Ads when users know what they want and are searching for it. Use ChatGPT Ads when users are researching, asking questions, and seeking recommendations. The best strategy often includes both.

How Targeting Differs
Google Ads: Keyword-Based
Google Ads matches your ads to specific keywords users search for. You bid on terms like "buy running shoes" or "best CRM software". The system also uses audience data, browsing history, and demographics to refine targeting.
This works well for high-intent searches where users know what they're looking for and are ready to take action.
ChatGPT Ads: Conversation-Based
ChatGPT ads don't use keyword bidding. Instead, ads appear when the conversation context is relevant to your product or service. OpenAI's system understands the full conversation, not just individual words.
This works well for users who are researching, comparing options, or seeking recommendations. They're engaging with AI to help them make decisions.
When to Use Each Platform
Use ChatGPT Ads When:
- Your customers research before buying
- Products require explanation or comparison
- You want lower competition and costs
- You're targeting the consideration phase
- Your product answers common questions
Use Google Ads When:
- Users search for specific products
- You need immediate, high-volume traffic
- You want granular keyword control
- You need display, video, or shopping ads
- You're targeting transactional intent
Key Differences Explained
User Intent and Behaviour
Google searchers often have specific, transactional intent. They search "buy iPhone 15 Pro Max" or "best pizza near me". ChatGPT users typically have exploratory intent. They ask "what should I look for in a new phone?" or "help me plan dinner for 4 people".
This difference is crucial. ChatGPT ads reach people earlier in their decision process, when they're forming opinions rather than executing purchases.
Competition and Costs
Google Ads is a mature, competitive marketplace. Popular keywords can cost $50+ per click in some industries. ChatGPT ads launched in January 2026 and have far less advertiser competition.
Early adopters of ChatGPT ads may benefit from lower costs and less competition, similar to how early Google Ads advertisers had advantages.
Privacy and Data
Google Ads uses extensive user data for targeting, including search history, browsing behaviour, and demographic profiles. ChatGPT ads rely on conversational context. OpenAI has stated that conversations stay private from advertisers and they don't sell user data.
Ad Experience
Google Ads appear as clearly marked results at the top of search pages, or as display banners across the web. ChatGPT ads appear at the bottom of AI responses, positioned as helpful recommendations after the AI's answer.
The ChatGPT ad experience is more integrated into helpful content, which may affect how users perceive and interact with ads.

Book a Strategy CallCan You Use Both?
Yes, and most brands should. ChatGPT ads and Google Ads complement each other by reaching users at different stages:
- ChatGPT: Reach users during research and consideration, when they're forming opinions
- Google: Reach users when they're ready to act, searching for specific solutions
A user might ask ChatGPT "what features should I look for in project management software", see your ad, and later search Google for your brand name. The platforms work together.
Tracking and Attribution
Google Ads offers mature tracking with conversion pixels, Google Analytics integration, and detailed attribution models. ChatGPT ads tracking is still developing as the platform is new.
Consider that ChatGPT ads may influence purchases that are later attributed to other channels. Users who learn about your product through ChatGPT might convert through Google search or direct visits.
Frequently Asked Questions
Are ChatGPT ads replacing Google Ads?
No. ChatGPT ads are a new channel that complements Google Ads. They reach users in a different context (conversational research vs. keyword search) and at different stages of the buying journey. Most brands will benefit from using both.
Which is cheaper: ChatGPT ads or Google Ads?
ChatGPT ads are currently cheaper due to lower competition (the platform is new). However, costs vary by industry and will likely increase as more advertisers adopt the platform. See our ChatGPT ads cost guide for current pricing data.
Should I move my Google Ads budget to ChatGPT?
We recommend testing ChatGPT ads with a portion of your budget rather than replacing Google Ads entirely. Start with 10-20% of budget to learn what works, then adjust based on results. Each platform reaches different user intents.
Can I use the same ad copy for both platforms?
You can, but it's not optimal. ChatGPT ads appear within conversational contexts, so ad copy that sounds like a helpful recommendation performs better than aggressive sales copy. Google Ads can be more direct since users expect promotional content in search results.
