I love Twitter. And I really love the idea that you can earn money with Twitter. Of course, I thought that it was too good to be true, but then I came across Sponsored Tweets and realized that it is, in fact, legitimate. In fact, I earn $0.35 for every accepted Tweet.
Basically, you sign up with the website, provide information about your Twitter account---set your price, list your number of followers, provide relevant tags, and choose which kinds of ads you will accept---and then you're good to go. Once an offer is available that matches up with your tags and information, Sponsored Tweets will contact you and you can either accept or decline the offer. Once you complete the task, the money will be credited to your account. After your account reaches the payment threshold ($50), you'll be able to withdraw your earnings.
Of course, you'll want to be wary because too many sponsored Tweets may cause you to lose followers. Just be open and honest, and always disclose the fact that you're Tweeting for cash. In fact, disclosure is MANDATORY when it comes to Sponsored Tweets.
