You earn immediate income with pay per tweet, while with PPC you need to wait until people click on your ads.
After you sign up for free, the pay per tweet system attracts advertisers to you based upon your twitter profile, followers and keywords. When an advertiser wants you to send a tweet, you will receive an email. At this point you have effectively made a sale, all that remains is for the tweet to be processed.
You can accept or reject the tweet offer. You can ask for tweets written by the advertiser, tweets written by you or both. After the tweet is accepted it will be tweeted for you and your account will be credited with the tweet price.
