The immense popularity of internet income sources have resulted in a number of people becoming interested in it. However, all the sources available online are not legitimate ones. So how do you make out the legitimate ones from the one that are basically scams? Here are a few things that can help you:

1. Trust Your Instincts-as in all other cases, your instincts are your best guide when you need to decide on the legitimacy of a site. Don’t go by the attractive websites and huge announcements of high figure internet incomes- trust your reason! If the site is guaranteeing $100000 a day without an effort, chances are that it is a fake! 
2.  Look at the Details- lookout for sites that claim that you can make thousands of dollars a week from the first week itself- you can’t! No matter what you are selling or what you are doing, EVERY business has a ‘gestation period’! If you are inexperienced in your field, there is no way you can earn thousands in internet income right from the first week itself!
3. Are They Charging You Right At The Outset? – There are a number of online sites that charge you a small amount before you start earning an internet income. While some may be legitimate in their demands (they will be providing you training or software in return), some may be scams!Be very careful when you are charging the amount to your credit card. There are also sites that require you to fill in personal details before you start earning. Always try to find out more about the concern before you give them any money. If you can make a call and get the details, by all means do so. If the phone numbers are provided, verify them before you pay out that amount (no matter how small)!
4. Do a Keyword Search- keyword searches are one of the best ways in which you can find out more about the concern. If you have any concerns regarding the company, do a keyword search and find out what they deal in and what others have to say. You can even try a keyword search with the name of the company and the word ‘scam’! That will tell you what the concern is up to!
5. Use the Forums- online forums are great at finding out what people are saying about the concern! Ask members whether they know anything about it. A word of caution though- look for a number of opinions, instead of confining yourself to a few! There may be some people who give you negative feedbacks simply because they were unwilling to put in the work required!

Consider these points in detail you go for a particular internet income source- and then sit back while the money pours in!
