It’s sometimes hard to comprehend just how much people love t-shirts. And with the right niche, marketing and tools, you can create an online t-shirt business that makes you extra money online while you sleep. (Even Bloomberg and Forbes feature stories from entrepreneurs who've done just that.) Services like TeeSpring make it easier than ever to create a t-shirt drop-shipping business where they handle the sales, printing, and shipping, and you’re only responsible for design and marketing. Or you can even buy into well-established franchise businesses like Rhea Lana that sell fashionable, affordable kids clothing and get the backing of a proven organization to fuel your online sales.

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.

A good blog has the potential to earn you many referrals for more clients.[24]
Ideally, you will already have a website that contains articles and other affiliate offers similar to the ClickBank products you want to promote. If you haven't set one up yet though, don't worry. WordPress is a great free content management system that you can use to start a website and begin publishing articles immediately. Use your articles to draw readers in, then present your ClickBank affiliate offer within the article. You may also want to develop a newsletter for your own website and use it to promote your ClickBank offers to your audience as often as possible. (See: How To Monetize Your Website.)
But don't make the mistake of thinking this will be a passive source of income—you're on call whenever you have a guest and you'll always need to keep the place clean for incoming visitors. On top of just renting on Airbnb, consider offering your guests paid add-ons, like Lauren Gheysens', Royal Day Out in London, England—where she gives visitors a local's only tour of the city, complete with bespoke 18th century costumes.

Test websites. Remote usability testing means getting paid to navigate a website for the first time and giving feedback to the website owner.

For example, you might be asked to go through the process of selecting and purchasing an item on a retailer’s website.[1]
Tip: Aim for products with reasonable commission. No lower than let’s say 40 percent, to make your efforts worthwhile. Also, you should note that ClickBank deducts transaction fees from a sale. Here’s a calculator to help you calculate your actual commission. More so, you need to remember to disclose all your affiliate links and mark them as nofollow. Here are a few reasons as to why you need to do this.
