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.
Equally, you can charge businesses to ‘claim’ their listing, a method used by many large directory sites like Google Business and Yelp.

Other revenue streams include charging for ad space, adding affiliate links and even charging for services and products on your directory site.
Creating your own food blog, will not only be fun, but done well it should also be profitable. Link your site to affiliate cooking products, sell your food photos, create and sell your own physical cookbook, or launch a cooking app. Equally, you could turn your cooking blog into a membership site. You would then share all your content, including recipes, how to videos, food photographs, and much more, with only your paid up members.
This has become a popular business model for online entrepreneurs over the past several years, and will probably just continue to grow in popularity.

This is similar in concept to micro-tasks, except that it is oriented toward specific services, such as cleaning services, pest inspection, handyman services, house cleaning, lawn & garden services or any of the skilled trades. It might actually be more accurate to say that it is a platform where skilled service providers can offer their services to site visitors, similar to Angie’s List.
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. 
My name is Jamie Spencer and I have spent the past 5 years building money making blogs. After growing tired of the 9-5, commuting and never seeing my family I decided that I wanted to make some changes and launched my first blog. Since then I have launched lots of successful niche blogs and after selling my survivalist blog I decided to teach other people how to do the same.
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.

With drop shipping, you’re effectively partnering with a manufacturer or wholesaler to sell their products. This way, you don’t pay upfront costs to buy inventory, aren’t sitting on unsold items taking up expensive warehouse space, and don’t have to deal with shipping the products yourself. You simply create your site, fill it with drop shippable products, and drive in customers, with almost everything else done for you.
Last but not least, you can also earn money online by building an online community, although the monetization strategies you can pursue will vary a lot depending on your goals. You can build a community with a blog, for example. You can also build an online forum and charge people for membership. You could even build up a Facebook group and use your influence there to sell and promote products.
