can anyone tell how to make online money by doing online data entry jobs

Yes, there are a number of websites that pays for data entry jobs. But, it is really difficult to trust sites due to scam. I would have loved to direct you to some sites which could genuinely let you earn something for data entry. But there are a few which actually allows. I would suggest you a single site called microworkers dot com. You can search this site. This is a site which pays you to earn but you need about three months pre work. You can earn right from now if you have already established yourself online. I mean to say that if you had a blog for say about 3 months with atleast 30 posts or more, a forum with more than 50 posts, than you are in a likely position to earn from the time you joined. They ask you to complete some works and you could select the works based on the price tags given therein. You can earn quite good if you have some established sites as I had stated. Good luck. Else, I would ask you to go to odesk, another site which offers work online with remunerations.

I actually earn quite a bit per month doing online data entry. It took me quite awhile to find jobs that weren't scams, but I was able to find some great ones, and one that has become an ongoing assignment. If you look at my blog in my profile, I have provided reviews and information about the sites I currently earn from.

no data entry jobs are scam...dont go for these sites...Because no company likes to type its data by some non-professional people like us...although if you have facebook account..then you can earn really good money..
