Each platform serves a different user intent and content consumption pattern. TikTok excels at viral reach and top-of-funnel awareness-I've seen CPMs 30-40% lower than Meta in some verticals. But conversion rates? Usually 0.5-1% for direct response, versus 2-3% on Google Search or even 1.5% on Instagram Shopping.
- TikTok: high engagement, low friction, but weaker retargeting infrastructure.
- YouTube: longer dwell time, better for consideration-stage content.
- Search/Retail Media: pre-existing purchase intent, far higher ROAS.
Calling any single platform "best" ignores the funnel stage and audience you're after. Would need to see your actual metrics-CTR, conversion rate, CPA by channel-before agreeing.
