There’s plenty of work and clients to be found. If you know where to look. To start, you need to know if there is enough demand for your skill to make it worth the effort to go out looking for work. Start by searching for freelance postings on sites like Flexjobs, SolidGigs, Contena or one of the dozens of other skill-specific freelance job boards.
This isn’t to scare you off. I simply want you to know that this guide is going to focus solely on ways to make real, sustainable extra income online. Not just a few bucks. I want to share all the mistakes I've made that got me to where I am now so that you don’t have to go through them, and can build a successful online source of income for yourself.
It’s a (mostly) short term, higher risk, higher reward place to invest cash that has a low correlation with the stock market, but is far more passive than buying and managing properties, has more opportunity for diversification than private placements (minimums of 5-10K, rather than 100K), and most of the equity offerings (and all of the debt offerings) provide monthly or quarterly incomes. Unlike a REIT, you can choose exactly which projects you wish to invest in.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
Do you think it’s possible to build a blog from scratch, outsourcing the work from day one (assuming I have some cash that can cover the initial expenses until the blog generates enough income to at least break even)? In other words, do you think you could you have spent your $500 max per month for the writer, social media expert, etc to build your blog to the point it’s earning the same amount of money it does now?
Creating space for banner ads on your website is another way to generate a revenue from adverts. However, for this type of advertising, you will need to contact businesses directly and ask them if they would like to advertise on your website. The upside is that you can charge a set amount, or even a recurring monthly fee, to business to promote their services on your site. Using a WordPress plugin like AdSanity is an effective way to manage this type of advertising.
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.
High-ticket consulting or coaching: You could sell your own high-ticket consulting or coaching products from your website. You'll still need a website, merchant account, sales funnel, lead magnet and many other items. But you can easily earn a substantial amount of money from each individual customer, making it well worth the arduous setup required.
If you have an extra room in your house, consider listing it on Airbnb. Airbnb is a new way to travel for many people around the world. Instead of booking through expensive hotels, why not stay at someone's house? As a guest, you can choose high end to low end, choose to stay with other people or opt for privacy. As a host, it's a great way to make side money, utilize unused space, and meet new people! How much you can earn depends on your area so I recommend finding out by becoming an Airbnb host yourself!
