One huge red flag is any company that promises you a “get rich quick” marketing strategy. Although affiliate marketing can be good money, it’s by no means instantaneous. Stay away from anything that sounds too good to be true. Also, stay away from any merchant that wants to charge you startup costs. Additionally, use established affiliate programs to find your merchants. Read reviews and ask around. You’re not the only person trying to supplement income with this marketing strategy, so there are plenty of other professionals with whom to crowdsource.

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. 
Creating a Fan Page provides your business and brands with another branding outpost on the Web where prospects, customers, future employees, vendors, and even the media can find information about your company and the products and services you offer. Unlike Facebook's personal Profiles, which are member-only accessible, Facebook Fan Pages are public-facing by default; that is, people need not be logged into Facebook to view a business's or brand's Fan Page, so even more people have access to the information you post.
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.
Creating space for banner ads on your website is another way to generate a revenue from adverts. However, for this type of advertising, you will need to contact businesses directly and ask them if they would like to advertise on your website. The upside is that you can charge a set amount, or even a recurring monthly fee, to business to promote their services on your site. Using a WordPress plugin like AdSanity is an effective way to manage this type of advertising.
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.
We’ve all heard those horror stories about folks who accidentally published personal content to their employers’ social media channels -- a marketer’s worst nightmare. So to avoid publishing mishaps like those, assign Facebook Business Page roles only to the employees who absolutely need it for the work they do each day. And before you do that, be sure to provide adequate training to those who are new to social media management, so they aren't confused about when they should be hitting "publish," what they should be posting, if something should be scheduled first, and who they should be posting it as.
