Sell photos. If you have a decent camera and a good sense of light, color, and composition, you can take and sell stock photos – i.e. nondescript images that lend themselves to many applications and are commonly used to illustrate online articles or products – with minimal effort. Stock photos of locations (a fire hydrant, a bare wall near an interesting tree, or anything you might find as a default background image on your computer) are easier to take, but stock photos of people (i.e. people arguing, people kissing, people laughing) usually sell for more, as they have more uses and require the written legal consent of your subjects. Hunt for a reputable stock photo dealer or database that will pay you fairly before signing on with anyone.

Guides are freelancers with an ability to communicate well and good grammar and spelling skills.
Here’s a good example of how lead sales can work in real life: My second website, Life Insurance by Jeff, brings in a ton of traffic from people who are searching the web to find answers to life insurance questions. While I used to have the website set up so I could sell these people life insurance myself, it was a lot of work to process all the different requests and clients. As a result, I started selling the leads I gathered instead.
Websites like Survey Junkie will pay you a decent chunk of change for the low-maintenance, borderline mindless task of completing surveys. Companies want to understand consumers better, and one way they do that is by compensating survey-takers (a.k.a. you). Most surveys pay between $0.50 and $1.25, and many of them take less than 5 minutes to do. You can read our full Survey Junkie review for more info.
