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. 
I know starting a blog is a way to make extra money. I just wish it was not take so much time it is not easy. To come up with new things to write about plus getting the traffic to your site. Just like your list here no way you just set down and wrote this all at once it took a lot of research and searching your brain. Great info and thanks for taking the time to put it all together.
The hardest part in making extra money is always the FIRST STEP in how you can earn extra cash. These tips will serve as a spark for those who are really confused where and when they should start with this financial journey. Making money is not all about intelligence, it is all about making your intellect work for you to have money. It is the wit-the “street-smart” style of approaching things.
@dasjung Well the creative industry needs to get over it then. Makes them sound like a bunch of cry babies trying to make the world stop revolving. Everything is a scheme to make extra money. Including the work by the most serious, professional web designer. Every type of work has different levels of professionalism, and thank goodness we live in the U.S. where people are free to trade goods and services at the levels they deem appropriate. Free enterprise and liberty are beautiful words. I’m all for standards. I’m a CPA. But I’d never tell someone not to help people with taxes as a little side business. And that’s federal taxes! This is logo design. Logo design!My latest conversation: https://ptmoney.com/taking-time-off-work/
Retain some control. If you upload photos of yourself, or friends/family with consent, it's worth going for the 'rights managed' licence option – otherwise you'll have little to no control over how your images are used (eg, you could star in an ad for haemorrhoid cream). See Alamy's page on understanding stock image licensing for more on the different types of licences.
Blogging is also one of the cheapest ways to make money online, aside from the time and and intellectual input that you have to invest. As you begin to make money from your blogging efforts, you can easily outsource for greater scalability. I also use Bluehost and I like the fact that it seamlessly integrates or interfaces with WordPress. You can set-up a domain or subdomain in minutes and start blogging in seconds. I love it!
The first follows the startup path we outlined above: You have a disruptive idea for an app or piece of software, you validate the idea with real customers, and then raise money to hire developers or a development studio to build, launch, and scale your software. If you’ve done everything right, your software will be accepted to the Apple and Google Stores and you’ll make money every time someone downloads it or pays for a premium feature.
If you live near a university, there are likely all sorts of research studies looking for participants. While I was an undergrad at Virginia Tech, I got paid $500 to participate in a 6-week dietary study. The study provided all my meals and paid me, but I had to eat a 5,000 calorie diet of 50% fat for 6 weeks, plus I had multiple muscle biopsies, urine/blood testing, etc.
I have tried to sign up & complete cash for surveys in the past and then felt like I was being led down a rabitt’s hole, going from one “skip” and/or “submit” to another without ever, seemingly, actually completing the entire process. So, when I saw CashCrate recommended in ptmoney.com, I thought it was going to be more straight forward, but, alas, no, I entered the rabitt’s hole once again, coming up for air only after an entire hour spent hopping, skipping, and jumpring all over the place, netting 25 cents in earnings! Has this been anyone else’s experience and what has been done to remedy the situation? It seems like there must exist an insider’s trick or, at least, know-how that I am missing.
TaskRabbit. Are you willing to get your hands dirty? (Nothing shifty … we're talking, like, weeding somebody's garden.) People come to this site to find those willing to do various tasks for them, such as putting together a bookcase or running an errand for them. Do as many tasks as you want, and this could become quite the part-time (or full-time) job.
Prior to that group, they had an online community for teachers looking for lesson plans. That probably sounds pretty random, but it's crazy the type of communities you can build and rally people around. If it's something that you're passionate about yourself and you want to connect with others that have that same passion, then an online community is something you should definitely consider.
