As of my last update in September 2021, there are various legitimate websites where people can potentially earn money or rewards through various means. However, it's essential to approach online earning opportunities with caution and do thorough research, as there are also many scams and unreliable platforms out there. Keep in mind that online earning opportunities can vary based on your skills, interests, and location. Here are some popular and reputable websites that people have used to earn money online:

1. Upwork (www.upwork.com): A platform that connects freelancers with clients for various tasks, such as writing, graphic design, web development, and more.

2. Fiverr (www.fiverr.com): Similar to Upwork, Fiverr allows freelancers to offer their services (known as "gigs") at a fixed price.

3. Swagbucks (www.swagbucks.com): A popular online rewards platform where users can earn points (Swagbucks) for completing surveys, watching videos, shopping online, and more. These points can be redeemed for gift cards or cash.

4. Amazon Mechanical Turk (www.mturk.com): A crowdsourcing marketplace where individuals can complete small tasks, known as Human Intelligence Tasks (HITs), for pay.

5. UserTesting (www.usertesting.com): Test websites and apps and provide feedback for payment.

6. Teachable (www.teachable.com) and Udemy (www.udemy.com): Platforms where you can create and sell online courses.

7. Etsy (www.etsy.com): If you're crafty or have unique handmade items, you can open a shop on Etsy to sell your products.

8. YouTube (www.youtube.com): If you create engaging video content, you can earn money through YouTube's Partner Program by monetizing your videos with ads.

9. Patreon (www.patreon.com): A platform that allows creators to earn money by offering exclusive content and perks to their supporters (patrons).

Remember, the amount you can earn from these websites can vary significantly based on factors like your skills, the time you invest, and the demand for your services or products. Additionally, earnings are not guaranteed, and it's crucial to be cautious and avoid any platforms that promise unrealistic or get-rich-quick schemes.

Always research the websites you are interested in, read reviews from other users, and be wary of websites that require upfront fees or personal information. If an opportunity seems too good to be true, it likely is. As the online landscape is continually evolving, I recommend checking for more recent information and reviews to ensure the websites you choose are still reputable and reliable.
