As an internet entrepreneur, you'll need your own web presence:website, blog, social media platforms, landing pages, sales pages, banner ads, or e-commerce site.  But instead of selling your own products, you sell the products of other companies.  You can use several of these combinations, if you like, as long as you get your marketing message to the public. 
It’s one of the oldest and most proven ways to make money – buy low, sell high.  The buy low part comes from searching garage sales, estate sales, and even thrift stores to find items that are in good condition (“gently used”) but selling well below what they would if they were brand-new.  In this way, you might be able to acquire an item for $5, and later sell it for $50. 

I look for income streams that do not require significant amounts of work to maintain.  If I need to drastically increase the amount of product I sell or customers I attract to make good money, and that requires more of my own time to achieve, or cannot be easily outsourced to others (it often increases your labor just to organize outsourcers, so don’t assume outsourcing is a magic solution), that’s not the method for me. 

I recently stumbled on the Trim app and I have to say, this one is a game changer.  It’s a simple app that acts as your own personal financial manager.  Once you link your bank to the app, Trim analyzes your spending, finds subscriptions you need to cancel, negotiates your Comcast bill, finds you better car insurance, and more.  And of course, the app is free!  My bet is that it will only take a few days for Trim to put an extra $100 in your pocket.  So easy! 
Another strategy to make money online is to become a social marketing manager.  Being present on social media is key for any business that wants to attract new customers, promote their products and grow their following.  However, constantly posting, liking and commenting on the numerous social media channels is extremely time-consuming.  More and more businesses are recruiting social media managers to run and organize all their social media.  And to save money, social media employees are often employed as online freelancers.

When was the last time you went to a new restaurant without looking it up online beforehand?  Or bought a product that didn’t have at least a few 5-star reviews?  It seems like more and more our world is run on reviews.  And you can make money online by writing them.  Get started by creating accounts on sites like Vindale research, Software Judge, FameBit, CrowdTap, Influence Central, and Modern Mom.  However, before you run off and start writing, be sure to check the small print on each of these sites.  Writing reviews isn’t a huge source of guaranteed income and you want to make sure that it’s worth your time before you get going. 

Not very exciting work, but in high demand from bloggers and small businesses.  This involves setting up accounts on all of the social bookmarking services and then bookmarking your clients’ websites or latest blog posts to help them get more traffic.  You may be competing against software that does this, but in many folks’ opinions, it’s better to have a real person do it.  Even better is if you can goose your accounts with plenty of friends and become a star on a few of the services; then every site you bookmark has higher credibility and you can charge more.  To get an idea of the social media sites you will need to sign up for, start at socialmarker.com.
