Budget Allocation Framework

For a new campaign with no historical data:

- Meta: $20/day per ad set - Google Search: $30/day per campaign - TikTok: $20/day per ad group - LinkedIn: $50/day per campaign - YouTube: $30/day per campaign

1. Test for 7-14 days before making optimization decisions
2. Scale winners by 20% every 3-5 days (not more, to avoid audience fatigue)
