Creating and selling courses on your blog can be a successful way to make money online. The course itself should be relevant to your blog, and based on a topic that will benefit your audience. Although it may take time to create the course in the first instance, once completed, you can then repeatedly make money from the course each time you sell it.
A blog highlights your technical ability and showcases your ability to write blog posts. Your blog can be about different topics than those you write about for your clients. In fact, it should be on a topic that interests you. Visitors will see that you can not only write, but you can also build an online community. A good blog has the potential to earn you many referrals for more clients.
As someone who's been immersed in a number of online industries for quite some time, I know a thing or two about what it takes to succeed in this arena. However, just like you, I started at ground zero with little knowledge, but a great deal of passion. What I learned along the way were some invaluable lessons from failure that hurt at the time, but helped immensely in the grand scheme of things.
However, not matter what method you choose to make money online, understand that you might be able to make some money fast, but for the sizable returns, you'll need significant sweat equity. However, a year from now, you'll be happy you started today. Remember, time is far more valuable than money. Focus on creating passive income streams that will free up your time so that you can quit the rat race and focus on the things that matter. That's the important thing here.
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. 
To advertise my tutoring service I marketed using posters offline and eventually set up a website and marketed on classified sites as well. I charged $15 an hour and eventually had a few Korean clients. This idea eventually ballooned into a full on English school with a real world premises that I managed for eight months before closing down. It turned out to be an experiment that taught me I much preferred online business to bricks and mortar.
Some subjects are much better paid than others, so although you may love the idea of writing about travel (badly paid) a better bet would be a niche like finance (much higher rates of pay). Check out the Pro Blogger job board for high paid freelance writing jobs – other places to look might be Textbroker or you can look at the “gigs” section on Craigslist.
eBay is a great way to turn your unwanted things into a little spending money, but it isn’t just a place to sell your old Star Wars action figures. In fact, eBay’s global marketplace can offer a great way for canny traders to buy and sell their way to profit. By buying wholesale you can sell anything with a mark up. Even better, if you have the skills to make things people want to buy you could start your own home-based craft business, selling to customers around the world.
Understand how a niche website works. A niche website focuses on very targeted, specific information. The content must be specific, useful and interesting to your target audience. Successful niche websites get anywhere from 1,000 to 10,000 visitors per month. You build content on a particular keyword, and you make passive income with Google Adsense or through affiliate links.
Are you a professional in a field that can help answer questions for people looking for your expertise? Websites like JustAnswer and LivePerson match you up with people looking for answers to technical or professional questions. You can make money online by simply answering these questions and providing the right information to people based on their individualistic circumstances.
Whether you have a website or are still dreaming up ideas for a blog, you can also look into affiliate marketing. With affiliate marketing, you partner with brands and businesses within the content of your website. If you mention a product or service, you link to that produce or service using a unique affiliate code you received when you signed up for that particular affiliate program. From there, you’ll make money any time someone buys a product or service through your link.
