6 months of testing every major survey site, tracking actual hourly rate. Real numbers:
1. Respondent.io — $15-25/hr (B2B user research, needs professional background)
2. Prolific — $8-12/hr (academic surveys, consistent quality)
3. User Interviews — $10-20/hr (broader categories, harder to qualify)
4. Survey Junkie — $3-5/hr (decent volume, easy)
5. Swagbucks — $2-4/hr (beginner-friendly only)
6. InboxDollars — $1.50-3/hr (not recommended)
My recommendation: Prolific + Respondent as your core stack.
Combined ceiling: $600-900/month if you're in US/UK with professional background.
