Surveys

Another way that kids/teens can make money pretty easily is by taking surveys. Surveys sometimes take a while, but they sure are an easy way for kids to get paid.

Personally, I recommend a few survey sites. Here's what I use:

Surveyhead
Surveyhead's a great way to earn money. I would recommend this to other international people (outside the US, such as Malaysia etc.) because Surveyhead pay by check. Although you have to earn a lot of money before claiming, it's still a good way of earning money. No credit card details, no bulls***, just plain moneymaking, although you might get a little annoyed waiting for more surveys to come in.

Global Test Market
A really interesting one, this one, but this one's really international and it looks really professional.It is quite easily seen as one for the adults.  You guys should go try it though. The first day's always the worst one for this one, no money making on day 1.

Blogging

Perhaps the simplest yet hardest way of making money online. Reason being, firstly, you need to build up a big audience.

Another reason behind this is because you do indeed need to find ways to dominate in your niche/in what you're talking about. Blogging can be simple, being that you can write about whatever you want, and you're free from all boundaries.

To be successful, it's key to use social marketing here. What I mean is building a Twitter page and a Facebook page. This encourages audience engagement, that they will go back to visiting your blog more often. That's what you're trying to do, remember?

Once it's successful, you've got to find the best publisher ad network out there for you. From Bitvertiser to Google Adsense, there are many out there that can serve to your needs. From in-text link advertising with InfoLinks, to banner advertising with Hostergate, there are many out there that can serve to your advertising needs (to earn you money).

Affiliate Marketing

Well, let me break it down for you guys, affiliate marketing is in fact a method where two people benefit from some marketing.

It allows people to 'share traffic' by displaying something like ads for others and the other person doing the same for you. It is also where you sell products through another affiliate. You need a blog/website for this to happen as this means you put up banners, links, etc.

It's official definition in Wikipedia:

Affiliate marketing is a marketing practice in which a business rewards one or more affiliates for each visitor or customer brought about by the affiliate's marketing efforts.
