A spin-off for web designers is to offer a landing page creation service. Well-optimized landing pages can be the difference between a successful and a failing business. And, as creating the perfect landing page isn’t easy, this is a service many businesses are prepared to pay for. I know people who are earning 6 figures per year and all they do is create landing pages for businesses. There’s serious money to be made.
Similar to a YouTube vlogger, if you have a large following on Instagram then you could become an Instagram Influencer. You will be paid to promote products in your photos, from wearing certain clothes to action shots of you using particular merchandise. As your Instagram following grows, you may start out simply receiving freebies in return for a picture of you with the item in the shot. However, for those with followings running into millions, you can expect large payments to display products in your pictures. Use sites like Hype Factory to help connect you with companies prepared to pay for your influence.
Look through your attic and closets. It's time for a purge. Selling on eBay is an easy way for you to clear up the clutter in your home while making money. But you can also look at eBay as an income opportunity through its many business models. Besides selling your own stuff, you can browse garage sales to find inventory or even open your own eBay consignment business to sell other people's belongings while earning a cut.
Your camera's lens cap spends more time off than on. Being behind the camera and capturing everything from nature to the food on your plate is one of your favorite pastimes. You could be selling your photos online. Digital cameras and the Internet make it easier than ever for you to sell your photos. Upload your photos to sites like Fotolia, Shutterstock, iStockPhoto and DreamsTime. Their compensation plans vary by site but the concept is the same ... you earn money when someone purchases and downloads your photo.

Before getting started with any kind of “we’ll pay you some minimal amount to do stuff” service, read reviews. What are people saying about the payments? The opportunities? How long it takes to get paid? Are there any creative methods a person can use to maximize their profits for the work? Is the work something you can actually see yourself doing, or will you likely quit a few minutes after you’ve finished your first project?
Please note that some of the links below are affiliate links and at no additional cost to you, I will earn a commission. Know that I only recommend products, tools and learning resources I've personally used and believe are genuinely helpful, not because of the small commissions I make if you decide to purchase them. Most of all, I would never advocate for buying something that you can't afford or that you're not yet ready to implement.
If you're serious about making money online, start a blog. Blogging is one of the easiest and most sustainable income sources. As long as the blog is setup the right way, in the right niche, with the right content targeted at the right audience, and the offer is complementary to the content, you could make a tremendous amount of passive income from a blog.
It doesn’t pay much, but if you’re a healthy person and want to make a bit of extra money online, the AchieveMint app will reward you for doing things like walking, tracking your food, or taking health surveys. AchieveMint works by connecting to fitness apps you might already be using like Fitbit, RunKeeper, Healthkit, and MyFitnessPal and then giving you points for certain actions. For every 10,000 points, you earn $10 with no limit on your earnings.
Believe it or not, you don’t have to be a CPA to start bookkeeping. Just sign up for a bookkeeping course at a community college or even online (such as this course from The Accounting Coach). Once you complete a course, you can start earning, and the median salary is reportedly $34,000. (Some stay-at-home bookkeepers I've spoken with personally make more than $70,000.)

As well, I'd recommend checking out this resource if you want to take this business idea seriously and get started with a business plan for your personal fitness trainer business today.

Etsy: While Etsy's popularity has declined recently, it's still a great resource for selling handmade items online. No need for complex ecommerce sites or merchant accounts or any sort of automation. The company takes a commission of every sale and charges a small listing fee per item. But many still use Etsy as their primary source of income. The best part is that you can also sell digital products on here such as poster designs. 
Some businesses may be interested in adding other types of paid content to your website. This could include videos, podcasts, or any other material that would work with your site and help a business market itself. Always make sure that paid content isn’t too promotional. It needs to add value to your audience first and foremost, and not just present as an advert.
While it may be tempting to start blogs and sites that appeal to lots of top categories, this strategy may spread you out too thin and prevent you from ever truly optimizing any of these channels. Start with one niche that you are the most knowledgeable about, establish yourself as an expert and then expand out from there. Only then start working out other areas.
Ever since the idea of online auctions came into existence, the online selling market has been on the rise. Many are interested, but don’t know how to get started. There are still all kinds of ways to make money by selling online, whether you’re selling what you already have or buying and selling like a store. Before we get started, here are a few general tips when selling anything online:
28. Subscription – If you think of something valuable (newsletter, online magazine, etc.) that you can consistently offer on a certain basis (weekly, monthly, etc.), you may want to offer a subscription service. This could be a fee charged each time your product is sent out or on a monthly basis. Either way, this has to be something that your customers can only get by subscribing to your website.
Upwork: This website offers a great marketplace for selling just about any professional service. You don't need a merchant account, website of your own or anything else for that matter. All you need to do is be able to provide a high-quality service at a reasonable price. But be informed, you will have to compete with many others that are constantly bidding on open jobs.
