How Targeting Differs
Facebook Ads: Interest & Demographic Targeting
Facebook (Meta) uses extensive user data including age, location, interests, behaviors, purchase history, and online activity to target ads. You can create audiences based on demographics like "women 25-34 interested in fitness" or build lookalike audiences based on your best customers.
This works well for building brand awareness, reaching broad audience segments, and targeting users based on their interests rather than their immediate search intent.
ChatGPT Ads: Conversational Context Targeting
ChatGPT ads don't use demographic targeting. Instead, ads appear when the conversation context matches your product or service. OpenAI's system understands the full conversation flow, not individual keywords or user profiles.
This works well for high-intent scenarios where users are actively asking questions about solutions your product provides. Users are already in a problem-solving mindset.

Key Differences Explained
User Intent and Behaviour
Facebook users are scrolling through their feed, discovering content, and engaging with friends. Their mindset is social discovery. ChatGPT users are actively asking questions and seeking information. Their mindset is problem-solving and research.
This fundamental difference means ChatGPT reaches users in a more deliberate decision-making mode, while Facebook reaches users during broader social engagement and discovery.
Ad Formats and Creative
Facebook's strength is visual creative. Image ads, video ads, carousel ads, and Reels ads allow you to tell visual stories that capture attention in a crowded feed. ChatGPT ads are text-only, positioned as helpful recommendations after AI responses.
For products relying on visual appeal (fashion, food, home goods), Facebook excels. For services requiring explanation (software, consulting, professional services), ChatGPT's conversational format can be effective.
Competition and Costs
Facebook Ads is mature and competitive, especially in popular industries. Costs have risen significantly over the past 5 years as more advertisers compete for attention. ChatGPT ads launched in January 2026 with minimal competition.
Current ChatGPT ads CPCs are significantly lower than Facebook, making it attractive for budget-conscious advertisers. However, Facebook offers proven ROI data and mature optimization tools.
Privacy and Data
Facebook Ads relies on extensive user data collection including browsing behavior, purchase history, and demographic information. This enables precise targeting but raises privacy concerns.
ChatGPT ads use conversational context only. Conversations stay private from advertisers, and OpenAI doesn't sell user data. This appeals to privacy-conscious users but limits targeting precision.
Tracking and Attribution
Facebook offers mature pixel tracking, conversion tracking, and attribution modeling. You can measure ROI, track customer journeys, and optimize based on actual conversions.
ChatGPT ads tracking is still developing as the platform is new. You'll need to monitor clicks and conversions, understanding that attribution may be indirect (users learn about you in ChatGPT, convert elsewhere).

ChatGPT Ads Costs
ChatGPT ads pricing is typically lower due to minimal competition. Early data suggests CPCs range from $0.50-$3.00 depending on industry. CPA varies widely based on your conversion funnel (generally $5-$50 per acquisition in early adopter data).
Facebook Ads Costs
Facebook CPCs vary significantly by industry and audience, typically ranging from $0.50-$3.50+. CPM (cost per thousand impressions) varies from $5-$15+. Mature audiences (like e-commerce) cost more due to competition. Some premium industries may see CPCs exceeding $5.
Cost-Effectiveness Comparison
ChatGPT ads may offer better cost-per-click currently, but Facebook offers more established ROI tracking. Your choice depends on your industry, product, and whether you prioritize low costs (ChatGPT early advantage) or proven attribution (Facebook's maturity).
Can You Use Both?
Absolutely, and this is the recommended approach. ChatGPT and Facebook ads complement each other by reaching users at different points in their journey:
- Facebook: Build initial awareness among broad audiences interested in your category
- ChatGPT: Reach engaged researchers and decision-makers actively seeking solutions
- Together: A customer might see your Facebook ad, become interested, then search ChatGPT for solutions, see your ad again, and convert
Media Mix Strategy
For Brand Awareness Focus
Allocate 70-80% to Facebook for reach and brand-building, with 20-30% to ChatGPT for high-intent capture. Facebook's visual formats build awareness while ChatGPT captures researchers.
For Lead Generation Focus
Allocate 40-50% to ChatGPT for high-intent leads, 50-60% to Facebook for broader reach. ChatGPT users are already in research mode, making them higher-quality leads.
For E-commerce Focus
Balance depends on your product. Visual products benefit more from Facebook (60-70% budget). Service-based products benefit from ChatGPT (50-60% budget). Test both and optimize based on ROAS.
