There are many medical research firms that perform testing on human volunteers. The tests can run from a few hours to a month or more and they all pay relatively well. Long duration tests sometimes require you to stay on the firms’ property in order to properly evaluate you, but you can receive several thousand dollars for your time. These tests almost always require you to take an experimental drug that has been proven safe in animals, but human tests are required before it can be brought to market.
23. Affiliates – There are many affiliate networks, such as FlexOffers and CJ Affiliate that allow you to promote other people’s products and services. You simply put a link or a banner on your page and then you get a percentage if someone clicks through and buys the product/service. You’ll want to select products that are specifically within your blog’s category.This is an effective way to earn money once you have the traffic coming to your blog.
Whether you have a website or are still dreaming up ideas for a blog, you can also look into affiliate marketing. With affiliate marketing, you partner with brands and businesses within the content of your website. If you mention a product or service, you link to that produce or service using a unique affiliate code you received when you signed up for that particular affiliate program. From there, you’ll make money any time someone buys a product or service through your link.
