Tip: Focus on a specific group—like “self-care for busy moms” or “mental health tips for students.”

🧘‍♀️ 2. Spirituality & Personal Growth

Why it works: The rise of tarot, astrology, and manifestation has created a booming niche for people looking for deeper meaning and inner peace.

Affiliate opportunities:

🐾 7. Pet Products & Services

Why it works: People love their pets—and they’ll spend good money to keep them happy and healthy.

Affiliate opportunities:

Tip: Choose a specific pet type (like dogs, cats, or exotic pets), and review gear or share training tips.

🔧 Bonus Tip: Find Your “Niche Within a Niche”

Don’t just go broad like “fitness” or “health.” Instead:

• “Fitness for new moms after C-section”
• “Budget vegan recipes for college students”
• “Productivity tools for ADHD creatives”

This strategy helps you stand out, connect deeply with a specific audience, and convert way better.
