Considering that most marketing involves some form of published media, it is almost (though not entirely) redundant to call 'content marketing' anything other than simply 'marketing'. There are, of course, other forms of marketing (in-person marketing, telephone-based marketing, word of mouth marketing, etc.) where the label is more useful for identifying the type of marketing. However, even these are usually merely presenting content that they are marketing as information in a way that is different from traditional print, radio, TV, film, email, or web media.
Tutor students. If you have an academic specialty and can squeeze in a couple of hours during the week while Junior is taking a nap or Janie is at gymnastics, share your knowledge with struggling students. Find students looking to improve their grades on your own through your kids' schools – check a site such as Craigslist.org to gauge hourly rates in your area – or sign on with an online tutoring company, such as Tutor.com. You must be available to tutor at least five hours a week and have a college degree to tutor certain subjects for Tutor.com. Tutoring is done virtually from home via a computer, not in person. Tutor.com tutors are paid an hourly rate based on the subject.
Have an extra room in the house? Try renting it out on Airbnb.com. According to Smart Asset, you can pay up to 81% of your rent by listing one room in a two-bedroom home. If you're really looking to ring in the cash, renting out a private home or apartment is the way to go. According to Smart Asset's findings, rates for full apartments are significantly higher than those for just rooms, with annual profits ranging from $15,000 to $31,000 for a two-bedroom apartment.
