$100 a month is not that much , you can hit that figure either by a blog or web poral . Just do the thing which give you peace of mind . Earning money is quite simple if you will be fair , remember that always ! Regards, MB
Depends on if the website is offering a product or service to generate revenue or if it is just offering content and making money on ads.
Both can work just as well as the other. You just have to make sure that you write good quality content, get lots of backlinks everyday, and advertise to attract people to your website.
