Why Most Bloggers Choose the Wrong Niche (And How to Avoid Their Mistakes)
Before diving into the selection process, let’s address the biggest niche selection mistakes that doom most blogs

Following your passion without considering market demand leads to blogs nobody reads.
The Competition Crush
Entering oversaturated niches like "weight loss" or "make money online" without a specific angle.

Choosing niches with high traffic but low monetization potential (like general entertainment).
The Knowledge Gap
Selecting niches you know nothing about, leading to thin, uninspired content.
The solution? A systematic, AI-powered approach that balances passion, expertise, market demand, and profit potential.
