YouTube细分机会发现器

Act as a top-tier YouTube strategist. I'm starting a YouTube channel from zero. Analyze the current YouTube landscape and give me a ranked list of the top 10 niches with high CPM (Cost Per Mille), relatively low competition, and evergreen demand. For each niche, include: * Estimated average CPM * Content creation difficulty (1-10) * At least 2 alternative monetization methods beyond AdSense (like affiliate programs or digital products) * A catchy 3-word channel concept Rank everything by an 'opportunity score' that balances CPM and competition. Avoid overly saturated niches unless the CPM is extremely high.
