Google Ads vs Facebook Ads: A Decision Framework
Choose a platform from customer intent, creative evidence, measurement readiness, and operational constraints—not generic CPC tables.

Advertising Platform Decisions
Agency decision frameworks for choosing advertising and research surfaces from customer intent, creative fit, measurement readiness, and evidence.
Direct answer
What this topic helps an agency decide
Choose an advertising platform from customer intent, creative fit, measurement readiness, operational capacity, and first-party economics—not a universal CPC table. Public ads can show how brands adapt offers and creative to a platform, but they cannot prove which channel will be profitable for your account. Use a comparable test plan and decide from qualified business outcomes.

Common questions
Questions agencies ask about advertising platform decisions
Which advertising platform is cheapest?
There is no universally cheapest platform. Auction conditions, audience, offer, creative, conversion quality, measurement, geography, and account history all affect economics. Compare qualified outcomes from your own controlled tests.
Can competitor ads reveal which platform performs best?
No. Public ads can reveal visible execution and activity context, but they cannot establish budget, conversion quality, profit, incrementality, or the advertiser’s cross-channel attribution.
How should an agency run a fair platform comparison?
Keep the proposition and conversion definition comparable, adapt creative to each platform, use consistent geographies and learning windows, and judge qualified business outcomes rather than clicks or platform-reported conversions alone.
