can anyone tell me what is the best online business that one should do to earn a descent income?
i have worked in too many schemes but nothing is paying me out. please let me know some legal and nice and easy idea for earning an income from the internet.

There is not a single business predifined to be successful so you will have to find it out the hard way as every other member here in internet does it.

If you are interested in affiliate marketing then send me and email or PM me. I have already PMed you with the URl of my affiliate program.

Thanks.

There are a number of Online sourses to earn Cash.

Affiliate Programs
PPC
Domains & Hosting Reselling
And many more.

What i would like to suggest you is that you should rather work on any one and will will surely get sucess.

I suggest that you choose a topic that you're interested in, and make money off ads. Otherwise if you're not interested in it, then the site won't last long.

If you have your own website and access to the control panel then I suggest you use Revenue Sharing Programs such as Adsense, Chitika, Adbrite or Kotera. These are programs that pays you a certain amount from the advertisers fees for your clicking visitors. Instead of just letting your website just sit there atleast you know by adding one or two of these programs you're automated 24/7 for a nice income. Of course you need traffic too.

And traffic is only & only Problem in Online Business :P
