Twitter.com requires no email verification at all. So it's really easy to make 10 to 15 accounts within minutes. Here's a quick, simple guide on how to make $50 a day or more!
Now before starting you want to have atleast 50 followers on each account, You ideally want to be using a program that can do mass following such as HummingBird The reason being, when you follow someone, they generally follow you back.
It would be ideal to have all of your twitter accounts with 3000 followers, but it takes a little bit of time. So if you have 1000 followers on each account, you are off to a good start.
Okay, After you sign up, configure your multiple accounts in your account settings. Go over to the post ads and in the ad section, you should want to post ads that will give you 5-10 cents a click. 10 to 7 cents is probably ideal. Now thats out the way, Choose these ads to be posted to your twitter accounts.
Lets do some math, at 10 cents a click, you should make atleast $10 (100 clicks) out of your 1000+ followers. So thats about $10 on one account give or take.
Assuming you have roughly the amount of followers and accounts that i recommended to you.
Then multiply this by your 10 accounts. So thats $10 x 10 accounts = $100. There you have $100 dollars in a day, just from twitter!
This will obviously take some time in the beginning to get the followers, and also you'll want to have some natural tweets also, using a software like Tweetlater makes it easy.
