Ready to explore these secret side hustles? Here’s what each platform offers and how to get started:

1. Swagbucks: Earn rewards for online activities

Swagbucks has paid more than $500 million to members who complete simple tasks. You can earn money online by:

• Watching videos
• Taking surveys 
• Playing video games

Each task pays anywhere from a few cents to several dollars, depending on complexity and time required. Use the app for 10 to 25 minutes daily and you could earn $100 to $200 per month, according to Swagbucks.

You can redeem your points for gift cards to popular retailers like Walmart, Target, and Starbucks, or convert them to cash through PayPal once you have a verified account.

Swagbucks also offers cashback of up to 16% when you shop online at retailers including Amazon, Home Depot, Best Buy, Lowe’s, Walmart, and Macy’s. If you’re already shopping with these brands, it’s an easy way to earn extra cash on purchases you’d make anyway.

2. InboxDollars: Get paid for surveys and tasks

InboxDollars works similarly to Swagbucks, paying you for surveys, games, videos, app testing, and online shopping. Brands pay the platform for user feedback, so you’re helping companies improve their products while earning money.

Tasks typically pay between 25¢ and several dollars, based on complexity. Most surveys pay up to $5.

You can cash out via check, gift card, or PayPal once you reach $15 for your first payment. After that, you’ll need a $30 balance to withdraw funds.

3. Google Opinion Rewards: Share your opinion for cash

The Google Opinion Rewards survey app pays you for quick tasks like sharing purchase history, reviewing local businesses, and answering opinion polls.

These micro-surveys take under a minute and pay 10¢ to $1 each. You can cash out through Google Play credit or PayPal once you hit the $2 minimum.

The trade-off? Limited survey availability. You’ll receive notifications only when surveys match your location and profile, meaning you’ll typically earn just a few dollars per day. Still, it’s one of the easiest ways to earn money from your phone during spare moments.

4. UserTesting: Provide feedback on websites and apps

UserTesting pays you to share your thoughts on websites, apps, and prototypes through recorded video or audio feedback. Tests typically take 10 to 20 minutes, and you’ll walk through tasks while explaining your experience out loud.

To get started, complete UserTesting’s application process and set up a PayPal account (required for payments). You’ll need a decent microphone to record clear feedback. Once approved, you’ll receive test opportunities based on your profile and demographic.

Earnings vary by project complexity. Simple website reviews might pay $10, while testing complex prototypes can earn significantly more. You can track your earnings through the mobile app.

PayPal is the only payout option, with payments arriving two weeks after completing tests. There’s no minimum balance required to cash out.

5. Second to None: Become a mystery shopper

Second to None connects you with mystery shopping assignments where you evaluate customer experiences at restaurants, retail stores, and online businesses. Your detailed feedback helps companies improve their service quality.

Create a free account to access assignments that pay between $5 and $100, depending on complexity. You might test a new restaurant dish, evaluate a store’s checkout process, or assess how well staff handle customer questions.

Payments arrive via direct bank transfer once monthly, so expect delays between completing assignments and receiving payment. The work is flexible, but the payout schedule requires patience.

6. Shutterstock: Sell your photos and videos

If you enjoy photography, Shutterstock offers a way to earn passive income from your images. The platform has paid more than $1 billion to contributors who license their photos to businesses, marketers, and content creators.

You earn 15% to 40% of the licensing fee each time someone downloads your photos, typically ranging from a few cents to several dollars per download. Your earning percentage increases as your download count grows, rewarding consistent contributors—more photos mean more earning potential.

Shutterstock pays monthly between the 7th and 15th of the following month. You can withdraw funds to PayPal, Payoneer, or Skrill once you reach the $25 minimum balance.

7. Printful: Design and sell custom products

Got design skills and want to turn your creativity into cash? Printful lets you create and sell custom trending products like t-shirts, hoodies, phone cases, and tote bags without upfront costs or inventory management.

Here’s how it works: You design the product, Printful prints your products on demand when someone orders, and they handle shipping. Shopify users can install the Printful app to start selling even more easily. You keep the profit after Printful’s base costs. Aim for a 40% profit margin (as with all print-on-demand products), though you can charge more if you have a strong brand, unique design, and an existing customer base to tap into.

“With Printful, I really appreciate the ability to connect everything together,” says Raven Gibson, founder of Legendary Rootz, in Shopify Masters. “I have an idea. I’m able to go in, see if they have a product that serves that idea, get a sample created. Once it’s approved, it’s all connected to Shopify. I love it.”

8. Rover: Earn money as a pet caregiver

Love spending time with pets? Rover connects you with pet owners who need dog walking, pet sitting, or boarding services.

Create a profile specifying your services and availability. Pet owners browse profiles and book directly through the platform. Rates range from $15 to $40 per hour depending on the service, though Rover takes a 20% service fee from each booking.

The payout schedule beats most platforms: Payments appear in your account two days after completing services, then transfer to your bank within three to five business days.

9. TaskRabbit: Get paid for completing local tasks

TaskRabbit connects you with people who need help with furniture assembly, home repairs, cleaning, and administrative tasks. As a “Tasker,” you set your own rates and choose which jobs to accept.

You’ll need to pass an ID check and have the right tools for your chosen services (like a screwdriver for furniture assembly). All tasks have a one-hour minimum, with rates ranging from $15 to $100 per hour, based on complexity. TaskRabbit offers bonuses like “Complete 10 Tasks and Earn $100" to help new Taskers build momentum.

Payments process within five days after submitting your invoice and go directly to your bank account.

10. Upwork: Find freelance opportunities

Upwork connects freelancers with clients who need specific skills, from virtual assistance and graphic design to web development and copywriting. You can sign up for free and start bidding on jobs immediately.

The challenge? Competition is fierce. You might compete against thousands of freelancers for a single job. Stand out by optimizing your profile with client results, setting competitive rates, and building a strong portfolio.

Most gigs pay $15 to $40 an hour, with technical roles like business consulting reaching $100 or more an hour. Keep in mind Upwork takes a 10% to 15% service fee.

Payment timing depends on your contract type. Hourly work pays weekly (available for withdrawal after 10 days), while fixed-price projects clear in five days.

11. Teachable: Create and sell online courses

Turn your expertise into income by creating online courses on Teachable. You set the price and keep control of your content, making this a potentially lucrative passive income stream—create the course once, and sell it repeatedly.

The downside? Upfront costs. Creating your course content takes time and money. Teachable’s Starter plan allows you to publish one digital product for $29 monthly. You’ll also pay a 7.5% transaction fee on sales.

💡 Pro Tip: Consider using Shopify to sell digital products instead. You’ll avoid monthly platform fees and can integrate additional features like membership sites and consultation booking.

12. Wrapify: Get paid to advertise on your car

If you drive regularly—especially for commuting, rideshare, or delivery—Wrapify pays you to display ads on your vehicle.

Download the app and provide details about yourself, your car, and your driving patterns. When campaigns match your area and driving routes, Wrapify provides vinyl decals for your car.

You earn $200 to $450 monthly, based on mileage and location, with payments every two weeks via direct deposit. The trade-off? You’ll need to submit regular photos proving the ads remain intact and visible, and you’ll need to pass a background check and have a clean driving record to be approved.

13. Studypool: Earn money helping students with homework

Studypool connects tutors with students who need help across virtually every subject—from basic math and English to specialized topics like coding and law.

The platform claims tutors can earn up to $7,500 monthly, with top earners making over $60,000 annually. Studypool takes a 20% service fee from each completed job.

Beyond tutoring, you can create passive income by selling study materials like practice exams and lecture notes. Each time a student views your document, you earn up to $10.

You’ll need at least $50 to withdraw earnings via bank transfer or PayPal (though PayPal takes longer to process than direct deposit).

14. Prolific: Get paid to participate in academic research

Prolific pays you to participate in university research studies. Tasks might include playing behavioral games, sharing opinions on products, or evaluating AI models.

Start by completing an application and joining the waitlist. Once approved after identity verification and a practice task, you’ll receive invitations to participate in studies.

Prolific stands out for higher pay rates—there’s an $8 minimum hourly rate, significantly more than typical survey sites. You can withdraw earnings once you reach $6, with daily cashouts available through PayPal or direct deposit.

How to choose the right money-making website

Not all earning opportunities fit every person or schedule. Here’s how to find the platforms that work best for you:

Consider your skills and interests

Building sustainable income takes time and consistency. You’re more likely to stick with platforms you actually enjoy using.

Look for opportunities that match your interests and existing experience. If you tutored your nephew last summer, Studypool might be a natural fit. Love assembling flat-pack furniture? TaskRabbit could turn that hobby into cash.

Evaluate time commitment vs. earning potential

Most platforms promise “easy money in your spare time,” but earning significant income often requires substantial time investment—hours spent applying for gigs, completing tasks, or building your reputation.

Be realistic about your availability. If you’re working full-time with only weekend hours to spare, freelancing platforms might not offer the best return. Car advertising through Wrapify could be more practical since it monetizes time you’re already spending commuting.

Understand payment methods and thresholds

Fast earning doesn’t always mean fast payment. Some money-making websites have significant delays—Second to None pays monthly, so May earnings won’t arrive until June.

Check minimum withdrawal amounts too. If surveys pay $1 each but require a $20 minimum payout, you’ll wait weeks to see money. Factor in platform fees as well—that $15 hourly rate looks less attractive when the platform keeps 20%.

Assess website legitimacy

Online earning scams are everywhere, making “Is this website legit?” a crucial question before joining any platform. Many fraudulent schemes masquerade as legitimate earning opportunities, particularly pyramid schemes that make most of their money from membership fees rather than actual products or services.

Legitimate money-making websites have diverse reviews on independent forums like Reddit and Trustpilot, They provide clear explanations of exactly how you’ll earn money and share genuine testimonials from real users.

Red flags to watch out for include:

• Lack of customer support
• Websites that require upfront fees to join
• Platforms with vague payout terms or earning schedules
• Suspicious domain names with hyphens or misspelled words
• Claims that sound too good to be true (“Get rich quick!” or “Guaranteed income!”)

Build your own income stream with Shopify

The most sustainable way to earn money online? Create your own business. With an online store, you control your products, pricing, and customer base completely.

Shopify makes launching an ecommerce business straightforward, with built-in payment processing, inventory management, and checkout tools. Whether you’re selling handmade products or launching a dropshipping business, you’re building an asset that grows over time—no secrets required.
