23. Affiliates – There are many affiliate networks, such as FlexOffers and CJ Affiliate that allow you to promote other people’s products and services. You simply put a link or a banner on your page and then you get a percentage if someone clicks through and buys the product/service. You’ll want to select products that are specifically within your blog’s category.This is an effective way to earn money once you have the traffic coming to your blog.
Again, if your blog has a large reader base, then businesses may be interested in paying you to review their services or products. Not only will you get a free trial using whatever these businesses are selling, but you will also get a fee for writing them a review and posting it to your site. Paid reviews (and other paid and sponsored content) can be big money, so advertise this service on your contact page to generate business.

19. eBay – Of course you can’t read an article about making money online that doesn’t mention eBay. You can start an eBay store and get serious about it or you can just sell some stuff to declutter your home. Either way, I’ve made my fair share from selling on eBay and it’s still a popular way to earn money. If you decide to start an actual eBay store, you’ll want to find a drop-ship business like Doba that will store and ship items straight to your customers so you don’t have to deal with an inventory.
How many email newsletters are you bombarded with every single day? There’s a reason for that. Marketing to an actively interested group of email subscribers is one of the best ways to make money online. There have even been million-dollar businesses built from simple email newsletters like TheSkimm, or Mister Spoils. Each newsletter targets a specific type of user with interesting, daily content, while also partnering with relevant companies and affiliates to bring in extra money. If this seems daunting, it’s not. Tools like MailChimp, ConvertKit and AWeber make it easier than ever to get started with email marketing. And another great option to consider (with the largest free plan available) is SendPulse, with their ability to send up to 15,000 emails per month to 2,500 subscribers, and then affordable plans starting at under $10/month as you grow from there.
Do you constantly come up with witty one-liners? Do you dream of the days of Mad Men-style advertising? If you’ve got some branding chops or just come up with imaginative copy, there are lots of opportunities to make money online through company naming and slogan contests. If you think you have a knack for names check out the Squadhelp platform where you can earn a little extra money online by naming brands, services, products, company slogans and even help out on the logo design front if you've got the chops.

Great article, I have tried a few over the years. I had a side business cleaning offices for years. It did great, but I hated never being able to take more than 3-4 days vacation, so I eventually gave up. I tried MTurk, but if you multiplied my earnings on an hourly basis, it was a little over $6/hr. My blog is much worse, probably less than $0.25/hr.

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. 
More than ever, writers are needed to formulate news articles, create content, and come up with the creative ideas that fill the pages of nearly every site on the Internet. And although many bigger sites have in-house writers, a growing number of sites outsource their content and hire freelance writers and content creators. Writing experience is very helpful, but what you really need to get started are drive, ambition, and the ability to find a unique angle on events that happen every day.
Freelance writing is such a great industry to get involved in if you want to work remotely. There’s plenty of work available and it’s typically one of the most flexible gigs in terms of scheduling. (You can often do the work whenever and wherever you choose.) Even better, it’s pretty easy to get started with a degree or previous writing experience.

Writing copy for websites is another great freelancing option for those who have a way with words. Copywriting can involve writing the text for websites, press releases, promotional offline materials including leaflets and brochures, and any other professional text for businesses. While writing blog posts is well paid it won’t make you as much money as writing copy for sales pages. However, clients can be more fussy, as they want the highest quality writing for the forefront of their website or advertising campaigns. Many freelance writers offer both copywriting and blog writing amongst their services. This can be a good way to juggle regular but lower paid clients (blogging) with the higher paid but ad-hoc project based copy work.
If it’s not clear yet, information and expertise are two of the most consistent and lucrative ways to make extra money online. If you don’t like talking on the phone, you can sign up to get paid to answer professional questions on JustAnswer. There are thousands of questions being asked every month from people looking for help from lawyers, doctors, mechanics, vets, and more. To apply, you’ll need to supply your professional verification, resume, and a form of identification.

Become an Amazon Associate and then use Keyword planner to find an in-demand niche: With more than a million different products to choose from and up to 10% commission the sales you drive, Amazon’s affiliate program is a great place to get started. Browse their available products and see what connects with you. Or take it a step further and use Google’s Keyword Planner to quickly check how many people are searching for a specific term. With affiliate marketing, the more relevant traffic you can pull in, the more you’ll make off your site.

What’s the catch? None, really. Cash back apps act as affiliates for many online merchants, which means that whenever you make a purchase through one of the apps, they get a small commission — but then, they give you a portion of that commission as “cash back”. For example, if I buy a pair of Nike shoes through the Ebates app (or website) and spend $75, Ebates may get a $10 commission but then they’ll pass $7 back to me. It’s basically a way to get sale prices on stuff that isn’t on sale!
