Writing is the first.
There is an increase in the demand for writers owing to the increase in the number of websites that are commercially driven.
If you have a good hand and good command of language, then you can start writing your way to your first check.
There are sites that pay you according to the number of people that have seen your article.
Generally, it's a good place to start.
Blogging falls in here too and it is related to writing.
Another good idea is creating a site and marketing an information product.
An information product in this case could be a 'how to guide'.
Most of the regular folks go to the internet looking for a guide on how to do something.
When you match this with the right kind of product, you can start making some good money.
You can make it in the form of an e-book or an audio, easily downloadable for a small fee.
One of the top selling entrepreneurial ideas in the internet is affiliate marketing.
It is one of the ideas that have created wealthy folk who gave up regular day jobs for a home based one.
It involves the marketing of a product on behalf of someone else and earning commissions on the number of products that you move.
You need a website if you want this to work better for you.
The good news is, the better you get the more you get paid.
The only secret in succeeding at this is finding a good affiliate program that has good commissions for its affiliates.
One final idea (final in this context and not in the list of ideas) is eBay auction selling.
EBay is regarded as one of the largest online markets today.
Since there are literally thousands of products being sold, you can join in the fun and auction off some stuff you don't need.
If not, you could try rebating.
That is where you buy an item from eBay at a lower price and selling it at a higher one.
When you play your cards right this way, you could earn a pretty decent income.
