I validate a local niche by watching real behavior, not opinions. I read local reviews and community posts to spot repeated problems. I check competitors for slow replies, outdated listings, or weak service. I call businesses as a customer to gauge demand. I talk casually with people who would pay and listen to how they describe the issue. I review pricing to see if profit is realistic. Finally, I run a small test like a simple ad or page. If people respond, I continue. If not, I stop.I don’t overthink it, but I also don’t rely on one metric.
