There are plenty ways of making money on the internet currently because there are a lot of businesses in which people are into and some of these people are looking for people that would help them scale it up.
What really matters is if you are actually very interested in any particular business venture. I learnt that if you really want to succeed on the internet it is very much important that you bring out your time to learn one thing first before venturing into another. That means, if you're interested in Affiliate marketing you have to learn affiliate marketing very well and invest your money on it and from there you can start making money before venturing into another.
If you don't have a skill you can also make money on the internet but what is required is your level of dedication and seriousness. Taking online surveys for example can probably fetch you a lot of money especially when you are in a developed country.
A lot of people combine about 5 to 10 survey websites and make some good amount of money in their free time.
Posting of paid to post platforms is probably one of the best ways of making money no matter your geographical location because everyone is supported.
