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.
Next, you’ll need the right tools. You can be as complicated or simple as you want depending on your comfort with audio equipment, but at the minimum you’ll want a microphone and software for recording your voice. Companies like Behringer, Blue, Focusrite, and others sell studio-quality plug-and-play podcast setups that can get you recording today.

Provide information about the key people in your business. A good business plan will not only describe the business and its services, but the people actually implementing and operating the business. Include a description of the key people involved, their roles in the company, and their background and suitability for contributing to this venture. Include their resumes in the appendix of your business plan. If your business is just you, that’s fine. Give yourself a title and write a brief bio highlighting your relevant experience that has prepared you for your current business idea.
Competition to get into top universities is as tough as it has ever been, so nervous parents are willing to pay handsomely for tutoring for their kids. You need an area of expertise—math, and specifically SAT math preparation, is always a favorite—but almost any subject will work. If you know how to market yourself locally, you can take advantage of parental paranoia and make money by tutoring right in your own home, or at a local library or coffee shop. Just make sure to do your homework on your local market in order to set prices and know which areas of expertise are most desired by parents in your area.

When one of your customers makes a purchase, you purchase the product from a third-party company (the drop shipper, usually a manufacturer or wholesaler) for a lower price. This process is as simple as forwarding the order from your customer, a process that can actually be completely automated. (Remember you don't have any risk here of buying inventory because the sale has already been made).
Open Yale Courses echoes Harvard Extension and Stanford Online, in that it offers only courses from Yale. While the site is similarly limited to topics taught at the school, Open Yale Courses offers a lot of videos of actual campus lectures. The availability of videos makes the site a great option if you’re looking for quality courses, but learn better by watching than by reading.
If you love to travel and find yourself randomly searching for airfare sales or browsing Lonely Planet, why not carve out a niche for yourself as a private travel agent? My friend, Mark Jackson did just that, making extra money online with his travel consulting side business. Start with word of mouth recommendations from friends who know they can count on you for the cheapest flights, and then move on and create a Facebook or LinkedIn group to invite people who want to stay on top of the latest deals. Eventually you could spin this into a full-time consultancy teaching people how to make their dream trip a reality.
You make money with ad revenue. Your first step is to create a YouTube account and start uploading videos. Then you enable monetization on your YouTube settings. Basically, this gives Google the go-ahead to include short AdSense ads with your videos, which you've seen if you’ve watched a YouTube video. When viewers click on those ads, you get paid.
You can absolutely use websites like eBay and Etsy! Try listing some items and making a professional Facebook page for yourself with a link to your eBay/Etsy pages. Then share the information with friends and family and get them to spread the word to people they know. Also, make sure that you have detailed descriptions and multiple pictures with anything you list online. This will help your listing show up in keyword searches, and you are more likely to sell something if the buyer knows a lot about what they are looking at.
The wedding industry is one that will most likely live in perpetuity. This is meant to be a special day for a couple, but often turns into a chore because of all the planning that comes with it. Because it is nearly impossible for brides and grooms to be able to enjoy the planning of their wedding, they often pay professionals to do it for them. If you have strong organizational skills, are communicative, pay attention to the little details, and love weddings, then you could set up shop from the comforts of your home. To get started and build a portfolio, offer your services to a friend or family member. From there, you can start charging other clients.
If you have experience with marketing, SEO, or a knack for getting people excited about the products and services you use on a regular basis, think about refining your skills and putting them to work making money online as a small business marketing consultant in your region—especially if you can become a local SEO expert and can help local clients rank higher in their search results.
