Abstract: Internet is really a good place to earn money, if you have enough patience.
Get Paid to Click
Sometimes, you can get paid for clicking links on the internet. This is a by-product of the fact that many advertisers pay websites for sending them traffic. And just as what have said above, cashback websites give you a share of their ad-revenue. Therefore, if they're paid just for sending traffic, you can also be paid just for clicking.
Cashback Shopping
When shopping online, choose "cashback" sites which will give you a small proportion (usually around 2% but up to 10%) of what you spend back in cash. These are advertising sites, paid for by providing leads to retailers. Generally speaking, they split some of their revenue with you in the form of cashback so as to encourage traffic.
As for How much money you can make? It's easy for you to earn $30 a month just by clicking paid links if you're consistent with the routine. Besides, set passwords on screen will make it easier.
Get Paid from Photograohs
Budding photographers can upload their digital photos to photo bank websites and earn royalties for each one sold. 10% of the sale price will go to the website, and you'll probably need to advertise elsewhere to drum up demand. However, if you have an interest in niche photography subjects, or take particularly beautiful shots, you could make good money.
Listen to Music? Get Paid to Reciew
Some websites pay you to review those unsigned music. You'll need a pretty open mind, as you can't choose specific genres, but once you've found a band you like you can vote for them and even buy stock in them to trade.
And if you're a musician, this way is also profitable since you could be financed for an album.
How much? Generally speaking, a dedicated fan who spend a couple of hours a night could get around £30/month. Not much, but not bad for a hobby. For a band, the sky's the limit if you're good enough.
Get Paid to Review Your Holiday
If you love travelling, it's possible for you to make money by regaling people with your holiday tales! You can simply write a destination guide and post it on the site. After people start clicking through to advertising links on your page, the site will pay you, as and when the cash comes in.
Tips for Writing a Winning Guide
Make sure that your guide is between 400 and 1000 words, ranging from romance and family fun to long-haul adventures, almost everything is OK. But the more informative and easy-to-read the guide, the higher rating it will get, and simultaneously, the more cash you can get.
What should you write about? Rather just picking country, choose a specific angle, and add some selling words, eg, "Five the Best Budget Hotels in London" instead of "Britain". Favourite destinations, such as Italy, will be well-covered, so think of a particular aspect that nobody else has covered and then add knowledge to it.
When writing, just think about that if you were going what would you want to know. So be specific - mention particular places, name hotels and explain why they are a good place to stay, describe the food and ambience in the restaurants you recommend.
Anyway, all the above ways are rather easy in making money. But never expect too much.
