Many big businesses are looking for social media influencers to become long-term ambassadors for their brand.

You may also be restricted from promoting other brands, so check out the small print before agreeing to any long-term agreements.
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. 
If you want to clear some space out in your house and have a big stack of books you’ve been holding onto for too long, you can make money selling your books and textbooks online.

Once you’ve gathered a list, put together a template outreach email (as you’ll be doing this over and over) that’s short and clear with expectations. Tell your potential interviewee who you are, what your podcast is about, and what you’re asking of them. Do a few test interviews with friends and family to make sure everything is being recorded at the quality you want and then book your first episode.
Using a food delivery service can’t necessarily earn you money, but it can help you save you money if you constantly find yourself throwing out half the food you buy.

There are several websites offering money to undergo online surveys, carry out online searches, and write reviews on products. To get the credit, one needs to disclose certain information to them including one's banking details. This is why you should use this route with utmost care. Some of them may even ask you to register with them before working on projects. The most important watch out in such projects is to stay away from websites offering money that appears too good to be true. Be careful while evaluating the reputation of the website as many of them could be a scam. Most sites promote businesses showing copies of cheque payments which may have been given to the middlemen only.
One of the cool things about Google AdSense is that it's so easy to get set up. If you have a blog or website, you can sign up for a free Google AdSense Account. From there, Google will give you a unique code that you will paste onto your website. Google takes it from there, tracking your page views, traffic, and earnings on your behalf. There is no upkeep or maintenance to get this thing going, which makes it a no-brainer if you have a website already.
