User testing is the weirdest side hustle on the list. You sign up for platforms where companies pay you to browse their website, try to complete a task, and narrate your thought process. A 15-minute test pays $10. A 60-minute live interview pays $60 to $150. And it’s genuinely low effort.
The catch: you’re not getting selected for every test. The platforms match you to tests based on demographic fit, and some profiles get way more invites than others. Here’s how to game that to earn $300 to $1,500 a month in spare time.
What user testing actually is
A company building a website or app wants to know if real humans can figure it out. They hire a third-party platform to send the website to users matching a target profile. The users:
- Open the URL
- Narrate out loud what they see, think, and try to do
- Record their screen and voice for 5 to 60 minutes
The company watches the recording later, sees where you got stuck, and uses that feedback to improve the product.
That’s it. You don’t need skills. You need to talk while you click.
Platforms ranked by pay
UserTesting (UserTesting.com): The giant. Pays $4 per 5-min test, $10 per 20-min test, $30 to $120 per live interview. High volume but competitive matching. This is the main one.
Userlytics: Pays $5 to $90 per test. Mix of recorded and live. Smaller test pool but often higher-paying ones.
Respondent: Best-paying platform. Studies pay $20 to $250 (and sometimes more for niche professions). Longer screening, fewer invites, but when they come they’re worth it.
UserInterviews: Long-form research interviews, usually 30 to 90 minutes. Pays $50 to $300. Excellent for professionals with specific backgrounds.
PlaybookUX: $5 to $100 per study. Good mix of quick tests and longer ones.
TestingTime: European-focused. Pays €50 to €150 per session.
TryMyUI: Entry-level. $10 per 20-min test. Steady but lower volume.
Prolific: Academic research-focused. $8 to $25/hour effective. Consistent and reliable pay.
Validately (now Userzoom): Mixed platforms after merger. Rates vary.
WhatUsersDo: UK-based. Pays around £5 per 20-min test.
Sign up for 4 to 6 of these. Each platform has its own audience of clients, so tests flow differently. Diversifying means more invites.
How to get selected more
Platforms match you to tests based on your profile. Two identical sign-ups can lead to very different invite rates. Some moves that compound:
Fill out every profile field
Platforms let you add way more than you initially fill out. Add:
- Your exact job title and industry
- Tools you use at work (specific software brands)
- Products and services you buy (banks, streaming, fitness, grocery delivery)
- Hobbies, pets, health conditions
- Household composition, income range
- Cars, home ownership
The more specific your profile, the more often you match a niche study (which pays more).
Ace the screener questions
Most studies start with 3 to 5 screener questions. Your answers get you in or filtered out. Three rules:
- Don’t lie. Platforms verify and lying gets your account closed.
- Don’t pattern-match too perfectly. If every answer sounds perfect for the study, they filter you out for looking coached.
- Give real, specific answers. “I use a bank app twice a week to check balance and once a month to pay a bill” beats “I use banking apps a lot.”
Respond fast
Platforms typically send invites to 10 to 50 people per study. First 3 to 5 to qualify and accept get the slot. Push notifications on for the apps. When an invite comes in, accept within 5 minutes.
Do tests well
Platforms rate you. High-rated testers get more invites. A well-rated tester:
- Talks continuously (no long silences)
- Narrates their thought process (“I expected a cart icon here but I don’t see one…”)
- Completes the full task (doesn’t rage-quit at a hiccup)
- Gives constructive feedback without being rude
After 20 or 30 highly-rated tests on a platform, your invite rate goes way up.
Equipment and setup
Basics:
- Laptop or desktop with working webcam and mic (some tests require mobile, so phone too)
- Quiet environment, or a cheap USB mic if your space is noisy
- Fast wifi (bad audio gets you rejected)
- Chrome browser (most test platforms use Chrome extensions)
You don’t need anything fancy. Your laptop’s built-in mic is often fine. Test it once with a free recorder and listen back. If your voice is clear, you’re good.
Realistic income picture
Casual (1 to 3 tests a week). $30 to $150/month. Takes 30 minutes of active work per week.
Steady (daily checker, 3 to 8 tests a week). $200 to $500/month. Takes 1 to 3 hours a week.
Aggressive (professional tester, specialized profile). $500 to $2,000/month. Takes 5 to 10 hours a week.
Niche professional. If you’re a developer, physician, compliance expert, small business owner, etc. you qualify for $100 to $300 interviews. Landing 2 to 4 a month puts you in the $500 to $1,200 range on part-time effort.
The niche professional move
Platforms like Respondent and UserInterviews pay a premium for hard-to-find participants. If your day job puts you in a specific professional category, you’re valuable. Common high-paying profiles:
- Software engineers (Python, JS, mobile, AI/ML)
- Healthcare workers (RNs, MDs, admin)
- Finance professionals (CPAs, bankers, advisors)
- Small business owners
- HR professionals
- Lawyers (especially specialized)
- IT administrators
- DevOps and cloud engineers
- Parents of kids in specific age ranges
- Pet owners of specific animals
- People with specific health conditions (paid for conditions-specific research)
If you’re in one of these, Respondent alone can put $500 to $1,500 a month in your pocket for 3 to 5 hours of interviews.
What to expect on a live interview
Live interviews are real 1:1 Zoom calls with a researcher. They’re conversational, not exams. Typical flow:
- Small talk, background questions (5 min)
- Task or screen-share while discussing it (30-45 min)
- Wrap-up questions and thank-you (5 min)
Dress casual. Have water nearby. The researchers are genuinely friendly. They’ve interviewed hundreds of people and just want honest reactions.
You get paid via PayPal, Amazon gift card, or sometimes direct deposit 3 to 14 days after the session.
The tax piece
If you earn over $600/year from any single platform, they 1099 you. Set aside 25 to 30% for taxes. Track expenses if you’re making real money (headphones, portion of internet, software).
For casual testers ($500 to $1,500/year total), keep receipts but don’t overthink it. Talk to a tax preparer if annual income from testing crosses $3,000.
The verdict
User testing isn’t a career. It’s found money. For 30 minutes to a few hours a week of spare-time work, you can realistically pull $300 to $1,000 a month while watching TV or on a work break. That’s a real emergency fund builder.
Keep the income visible. Side-hustle dollars that aren’t tracked tend to disappear into DoorDash orders. Spew auto-tags deposits (PayPal from UserTesting, direct deposits from Respondent) and shows you what you actually earned across all the platforms without you having to log into any of them. 30-day free trial.
Sign up for 3 to 5 platforms this week. Fill out every field. Do your first test. It’ll take an hour and you’ll have the rhythm figured out.
