🔍 Validate Your Ideas with NicheCheck

- ✅ Search volume - Is there demand?
- ✅ Revenue potential - What can you earn?
- ✅ Complexity score - How hard to build?
❓ Frequently Asked Questions
How do I pick between multiple ideas?
Validate all of them. Pick the one with: 1. Highest demand (search volume) 2. Lowest competition 3. Best fit for your skills 4. Clearest monetization
How much time should I spend validating?
1-2 weeks maximum. Validation paralysis is real. If data looks decent, build an MVP.
What if my idea has no competitors?
That's usually a red flag, not an opportunity. No competitors often means no demand. Look for adjacent markets.
Should I build what I know or learn something new?
Build what you know first. Your unfair advantage is understanding the problem deeply.
How do I know if my side project can become full-time?
When it consistently generates $5,000+/month with growth potential. Don't quit your job for $1,000 MRR.
