How I Earned R24,120 in 12 Months Sharing What I Already Know


Published: June 4, 2025 | Last Updated: May 29, 2026

Quick note about me: I'm Johenn M. Aphane, and I run Affiliate Pedagogy Hub (Pty) Ltd here in South Africa. I write about affiliate marketing and digital income on The Digital Wealth Journal because I want to share what actually works—not theory, but real results from real testing.

I'm a verified participant on UserInterviews.com. That means I've joined paid research studies where companies and researchers pay me to share my experience with social media marketing, affiliate marketing, and running an online business. This case study covers my full 12 months on the platform (June 2025 to May 2026)—what I earned, how often I qualified, how payments worked from South Africa, and whether it's worth your time.

Affiliate disclosure: This post has affiliate links. If you sign up through my link, I might earn a small commission at no extra cost to you. I only recommend what I've actually used. You'll also find the original non-affiliate links at the bottom so you can compare.



What I Tested

From June 2025 to May 2026, I tracked everything about my UserInterviews.com experience:

  • How many study invitations I got
  • How often I actually qualified
  • What I earned (in USD and ZAR)
  • How fast they paid me
  • What kinds of studies I did
  • How it worked as a South African participant (payment methods, time zones, tax stuff)

I wanted to know if this platform is legit and whether it's worth the time for South African creators like me who already juggle content creation, affiliate marketing, and family life.



What Is UserInterviews.com?

UserInterviews.com connects researchers with people who have specific expertise or experience. Companies use it to get feedback on products, marketing strategies, and business ideas. Unlike those survey sites that pay you R5 for 20 minutes of work, UserInterviews pays way more because they need people with real professional knowledge.

Here's how it works:

  1. You sign up for free and fill out your profile (your work background, skills, interests)
  2. You get emails when studies match your profile
  3. You answer screening questions to see if you qualify
  4. If you qualify, you join the study (video interview, survey, usability test, etc.)
  5. They pay you via PayPal after you finish

What kinds of studies?

  • One-on-one interviews: 30-90 minutes on Zoom, usually $50-$200 USD
  • Focus groups: 60-120 minutes with other participants, usually $75-$300 USD
  • Usability tests: 15-60 minutes testing a website or app, usually $25-$100 USD
  • Surveys: 5-30 minutes answering questions, usually $10-$75 USD
  • Diary studies: Multi-day tracking, usually $100-$500 USD

This isn't a high-volume thing. You won't get daily studies. But when you do qualify, the pay is solid.



My 12-Month Results

Let me give you the real numbers from my year on UserInterviews.com:

Study invitations I got: 47 over 12 months (about 3-4 per month)

Studies I applied to: 38 (I skipped 9 because of timing or topics I didn't know enough about)

Studies I qualified for: 14 (that's a 36.8% qualification rate)

Studies I actually completed: 12 (2 got cancelled last minute by the researchers)

Total I earned: $1,340 USD (about R24,120 ZAR based on the exchange rates during that time)

Average per study: $111.67 USD (about R2,010 ZAR)

Highest single payout: $250 USD for a 90-minute focus group about social media marketing for small businesses

Lowest single payout: $40 USD for a 20-minute usability test

How fast they paid: 7-10 business days after I finished each study

Total time I spent: About 18 hours over the whole year (including screening questions and the actual studies)

My effective hourly rate: $74.44 USD per hour (about R1,340 ZAR per hour)

That hourly rate is way higher than any survey site I've tested. But remember—this isn't consistent work. Some months I got multiple studies, other months nothing.



What Kinds of Studies I Did

One-on-one video interviews (7 studies)

These were my favorite. Researchers asked me about my experience with social media marketing, affiliate marketing, content creation, and running a small business. The conversations were professional and respectful. They genuinely wanted to understand how I do things and what challenges I face.

Duration: 45-90 minutes each Pay: $75-$200 USD per interview Format: Zoom calls with prepared questions

Focus groups (2 studies)

These were group discussions with 4-6 other professionals. We talked about social media challenges for small businesses and what features we look for in marketing tools. It was interesting hearing other people's perspectives while sharing mine.

Duration: 90-120 minutes each Pay: $150-$250 USD per session Format: Zoom with a moderator guiding the discussion

Usability tests (2 studies)

Quick tasks where I tested a social media scheduling tool and an affiliate dashboard. I recorded my screen while completing tasks and thinking out loud about what worked and what didn't.

Duration: 20-30 minutes each Pay: $40-$60 USD per test Format: Screen recording with some follow-up questions

Survey (1 study)

One straightforward survey about how content creators prefer to monetize their work. Multiple choice and some open-ended questions.

Duration: 15 minutes Pay: $50 USD Format: Online form



What Worked for Me

1. I filled out my profile completely

I didn't skip anything. I listed my law degree, my digital marketing training, my experience running Affiliate Pedagogy Hub, my blog work—everything. The more detail I gave, the better the study matches I got.

2. I responded fast

Studies fill up quickly. When I got an invitation email, I answered the screening questions within 24 hours. That helped me get in before spots filled up.

3. I was honest in screening questions

I didn't try to fake answers to qualify. If I didn't have the experience they needed, I said so. This meant I only got into studies where I could actually contribute something useful.

4. I gave detailed answers during studies

During interviews and focus groups, I shared real examples from my work. Researchers appreciated the specific, practical insights instead of generic answers. A few even invited me back for follow-up studies.

5. I prioritized flexible timing

I looked for studies with multiple time slot options or asynchronous tasks (like surveys). This worked better with my content schedule and family time.

6. My niche expertise helped

My specific background—affiliate marketing, social media for small businesses, being a South African entrepreneur—made me valuable for targeted studies. The more specific your expertise, the better your chances and payouts.



What Didn't Work

1. Low qualification rate

I only qualified for about 1 in 3 studies I applied to. Researchers have very specific needs. Even if you're close to what they want, you might not make the cut. That's just how it works.

2. Time zone headaches

I'm in South Africa (SAST, UTC+2). Many studies were scheduled for US or European business hours, which meant late nights or early mornings for me. I had to turn down several good-paying studies because of timing.

3. Inconsistent invitations

Some months I got 6-7 invitations. Other months, just 1 or 2. You can't predict when studies will come up, so you can't count on steady income.

4. PayPal fees eat into earnings

UserInterviews pays via PayPal, which works in South Africa but charges withdrawal fees (about 3-5%). Plus, the USD to ZAR conversion rate PayPal uses isn't always the best. I typically lost 5-10% to fees and conversion.

5. Last-minute cancellations

Two studies I qualified for got cancelled or rescheduled by researchers at the last minute. It doesn't happen often, but it's frustrating when you've cleared your schedule.

6. This isn't a main income source

Don't expect weekly studies or predictable money. This is supplementary income for people with specialized knowledge, not a replacement for real work.



What It's Like as a South African Participant

Payment:

PayPal is pretty much your only option. It works, but:

  • Withdrawal fees to your SA bank account are about 3-5%
  • PayPal's USD to ZAR conversion rate is usually a bit worse than market rates
  • After fees and conversion, you keep about 90-95% of what the study paid

Time zones:

This was my biggest challenge. South Africa is 6-7 hours ahead of US Eastern Time and 1-2 hours ahead of Europe. Most studies want real-time participation during their business hours, which can mean 10 PM or 5 AM for me.

My solution: I prioritized surveys, usability tests, and other asynchronous studies when possible. For interviews, I requested early morning or late evening slots when I could.

Tax (SARS compliance):

All income from UserInterviews counts as taxable income in South Africa. SARS wants you to declare international earnings. I keep records of all PayPal payments, study dates, and amounts. I report everything in ZAR using the exchange rate from the payment date.

If you're doing this, talk to a tax practitioner about how to declare it properly.

Internet and load shedding:

Video interviews need stable internet. Load shedding can mess things up. I use mobile data as backup and try to schedule studies during times when load shedding is less likely. If something goes wrong, I message the researcher immediately—they've always been understanding.

The upside:

Being a South African creator with digital marketing expertise actually makes me more valuable to researchers studying global markets. My perspective as someone serving international audiences from South Africa is unique, and researchers appreciate that.



How This Fits Into My Income

I don't rely on UserInterviews as my main income. It's a supplement that works alongside my core business:

My main income:

  • Affiliate marketing (blog, social media, email)
  • Digital products (ebooks and courses on Payhip)
  • Content creation

Supplementary income:

  • UserInterviews.com
  • Survey platforms (I track these separately)
  • Occasional freelance work

Why UserInterviews works as a supplement:

  1. The hourly rate ($74.44 USD/hour) beats most survey sites and many freelance gigs
  2. I'm paid for knowledge I already have—no extra training needed
  3. I choose which studies to join based on my schedule
  4. Participating keeps me updated on industry trends and new tools
  5. I've made professional contacts through some studies

Time breakdown:

UserInterviews takes about 1-2 hours per month on average (18 hours over 12 months). My core business takes 40-50 hours per week. So UserInterviews is less than 1% of my work time but brings in meaningful extra income.


Who Should Join?

You'll do well if you:

  • Have professional expertise (marketing, tech, business, healthcare, education, etc.)
  • Run a business or create content and have real-world experience to share
  • Are comfortable talking on camera or phone about your work
  • Want supplementary income, not a full-time job
  • Have a flexible schedule
  • Enjoy sharing insights and helping with research
  • Live in South Africa with a PayPal account and reliable internet

Skip it if you:

  • Expect consistent, high-volume income (this isn't a survey site)
  • Don't have specialized knowledge or professional experience
  • Aren't comfortable with video calls
  • Want passive income (you have to actively participate)
  • Have a rigid schedule
  • Don't have PayPal or don't want to deal with currency conversion


Pros and Cons from My Year

Pros:

  • High hourly rate ($74.44 USD/hour for me) compared to survey sites
  • Legitimate platform that pays on time
  • You're paid for expertise you already have
  • You choose which studies to join
  • Keeps you informed about industry trends
  • Professional, respectful researchers
  • PayPal works for South African participants
  • You help shape real products and business strategies

Cons:

  • Low qualification rate (I qualified for 36.8% of studies I applied to)
  • Inconsistent study availability
  • Time zone challenges for South Africans
  • PayPal fees and conversion reduce your earnings
  • Not a main income source
  • Occasional last-minute cancellations
  • You need specialized expertise


My Honest Take

After a full year as a verified participant, I think UserInterviews.com is absolutely worth joining if you have professional expertise in marketing, tech, business, or similar fields. But it's supplementary income, not primary.

Why I recommend it:

  • $74.44 USD per hour is excellent for side income
  • The platform is legitimate—they pay on time, researchers are professional
  • You're paid for knowledge you already have
  • Participating keeps you sharp on industry trends
  • You choose what fits your schedule

The reality check:

  • Don't expect weekly studies or predictable income
  • You'll only qualify for about 1 in 3 studies
  • Time zones are tricky for South Africans
  • PayPal fees take 5-10% off your earnings

For South African creators specifically:

UserInterviews works well if you:

  • Have expertise in digital marketing, social media, affiliate marketing, entrepreneurship, or tech
  • Have PayPal and are okay with managing currency conversion
  • Can handle occasional early morning or late evening studies
  • Focus on asynchronous studies when possible
  • Track everything for SARS

Bottom line:

I earned $1,340 USD (R24,120 ZAR) in 12 months with only 18 hours of work. That's solid supplementary income for minimal time. I'll keep participating in 2026, and I recommend it to other South African creators with professional knowledge.

But don't make this your main income. Build sustainable core streams (affiliate marketing, digital products, services) and use UserInterviews as a high-value extra.



Common Questions

How much can I realistically earn?

It varies a lot based on your expertise and how often you qualify. I made $1,340 USD (R24,120 ZAR) from 12 studies over a year. Some people earn more, some less. Don't expect consistent monthly income.

How often will I get study invitations?

I got 47 invitations over 12 months (about 3-4 per month). It depends on your profile and what researchers need. Some months you'll get several, other months none.

What's a normal qualification rate?

I qualified for 36.8% of studies I applied to (14 out of 38). That's typical. Researchers have very specific needs, so you won't qualify for most studies.

How long until I get paid?

Payments hit my PayPal 7-10 business days after I finished each study. UserInterviews is reliable with payments.

Does this work for South Africans?

Yes, but with some challenges. PayPal is your payment option (fees and conversion apply). Time zones can make scheduling hard. But the high hourly rate makes it worthwhile if you have the right expertise.

Do I pay tax on this in South Africa?

Yes. All UserInterviews income is taxable. SARS wants you to declare international income. Keep records of all payments and report in ZAR using the exchange rate from when you got paid. Talk to a tax practitioner for proper advice.

What expertise do researchers want?

Common areas: marketing, social media, tech, healthcare, finance, education, entrepreneurship, specific job roles. My background in social media marketing, affiliate marketing, and digital entrepreneurship made me a good fit for many studies.

Can I do this full-time?

No. Study availability is too inconsistent, and qualification rates are too low. Treat it as supplementary income alongside your main work.



My Final Thoughts

As a verified UserInterviews participant and South African digital entrepreneur, I've found this platform to be a legitimate, high-value side income for creators with specialized knowledge. The $74.44 USD per hour rate beats typical survey sites and many freelance gigs. Plus, participating keeps me updated on industry trends.

But UserInterviews isn't a replacement for consistent income. It's a supplement that works best alongside core business activities like affiliate marketing, digital products, or services.

For South African creators, the platform works despite time zone and payment challenges. The key is managing expectations: don't expect weekly studies or predictable money. Instead, see it as occasional high-value opportunities to get paid for your professional knowledge.

If you have specialized expertise in marketing, tech, business, or similar fields, I recommend joining. Fill out your profile completely, respond to invitations quickly, and prioritize studies that fit your schedule. Track everything for SARS, and treat it as a valuable supplement to your main income.

The digital economy rewards specialized knowledge. UserInterviews is one way to monetize what you already know while helping shape products and strategies that companies are building.
