I've been using
Tweet Attacks for a few weeks now. Using this program has got to be one of the easiest ways to get a ton of traffic to your sites. After two weeks of messing around with this program I have a few accounts that have about 400 followers each. I also have plenty more growing fast. I've tried other programs but they're a joke compared to tweet attacks.
If you follow these simple steps you won't need any other source of traffic.
1. Open a twitter account, edit the bio, change the design, and change out the pic. Wait at least 3 days before following people.
2. Run
Tweet Attacks and start following people. You don't want to just follow random people.
3. Use
http://twitterfeed.com/ to import feeds from your sites. If you don't have feeds there's still a content scaper in Tweet Attacks that can make tweets for you.
4. Rinse and repeat, if you only have one site/rss feed you can still make more twitter accounts. Although you have to be careful promoting the same site over several accounts.
5. After it's all set there's very little you need to do sense you can automate
Tweet Attacks
Just a tip, always keep the program up to date. The old versions such as 1.5.4 has some bugs and there's new features in the updated versions. Using the old one could even get your accounts banned sense it doesn't keep track of who you followed already and a few other reasons.
