You'll also need ecommerce software, fulfillment software, worry about warehousing, customer service, refunds and so on. But that's not all. You'll also need traffic. Think search engine optimization, Facebook ads, and other social media campaigns. Sound like a lot of work? Sure, it is. Especially if you do it all on your own. You could opt for Amazon's platform, which might be the easier route. But, then again, at the end of the day, this is a serious business, which could produce significant profits. So you're either all in or you're not.

A fitness site can have numerous revenue streams. Create healthy eating plans and recipes and lock them away as premium content. Promote and sell a fitness training course, eBook, or a series of videos. Or advertise your own personal fitness services on your site. Topfithub is  a good example of a fitness site with decent video content alongside product reviews.
Keep in mind though, you don’t need a website to do sponsored content since you can also get paid if you have a lot of social media followers. My wife has a pretty big Instagram following, and she gets all kinds of sponsorships. Not only does she get paid in cash, but we get a lot of free stuff, too. We’ve received free rugs, free lights, and free carpet cleaners. She only promotes things she loves though, so this strategy works really well for her.

11. Petsitting – this one doesn't require much explanation. You have a few options. You can offer occasional sitting services to those going on vacation or establish a steady clientele by offering dog walking services. If you are really wanting to ramp up your service package, you can even throw in a little lawn cleanup. A lot of pet owners are more than willing to pay for dooty duty these days. 

Dr. Rose wrote that she was about to give on in frustration, then, fortuitously, she ran across a pin that blared, “How To Make Your First Affiliate Sale in 24 Hours Using Pinterest.” She clicked it out o fcuriousity, then found out what the “catch” was. The link was to a purchase page for a book by that name. Not wanting to make the purchase — after all ,she’s been blogging for a couple of months, but still ahdn’t made any money, she thought to herself “How’s this possible?”
Another survey from VigLink offers a closer look at just how much income affiliate marketers are bringing in. According to the survey, 9% generated more than $50,000 in affiliate income in 2016. The majority, 65%, said they were making between 5% and 20% of their annual revenue from affiliate programs. The survey also showed a link between timeframe and revenues. Among the publishers with the largest revenues, 60% had been utilizing affiliate-marketing strategies for five years or more. 
E-books represent about 20 percent of all book sales in the U.S. The good news is you don’t have to be a publisher with deep pockets to get in on the action. As a solo internet entrepreneur, you can sell ebooks directly from your own website. You can sell your own works or sell a public domain work. Simply upload it to your website (or seller account on Amazon) and start publicizing it on your social media platforms, on your email list, your blog, website, etc.
Of course you want affiliates with high commissions, but they should also have a solid reputation with high conversions and low reversal rates (you get $0 if people cancel after signing up). If they’re part of an affiliate marketplace like ShareASale or ClickBank you can see some numbers there. Companies likes Amazon/SiteGround are safe bets, otherwise do your research (or track your affiliate links so you can monitor their performance). Avoid affiliates offering huge commissions since this probably means they’re struggling to acquire/retain customers naturally. This will hurt your numbers (specifically your conversions/reversal rates).
