I haven't heard of tweetattack but I have heard some good things about tweetdeck. Start following others on your twitter account that are of a link minded business or niche. Also consider adding a thanks for following auto responder so that your twitter fans know you are aware of the follow. You can also contact other tweeters directly and let them know that you would like for them to follow you. Those few items should get you started.
With Good practices? You can share interesting comments, participate in Trend topics worldwide and local, tweet links from news but associate them with hashtags so you are viewed by specific sectors.
Following people/companies that are related to your industry, posting relevant tweets, embedding the Follow On Twitter icon on your webpage/blog page are some of the methods you can use to get free followers. Though there are companies offering tons of twitter followers, its recommended not to go in for those things and rather grow your follower base naturally.
there's a way to get huge follower on twitter, not very pricey but these follower are not real. its good if you think numbers can give you some sort of impression to attract other real followers, but it can never return as buyer or visitor to your links. if you want a real follower, yes there are companies offering the service, but what they actually do is, they will need access to your twitter account and start following random people with hope these people will follow back. good companies or marketers will follow only people from the same niche as you are or have interest in what you offer, so when you get a follow back, these will be worthy. monitoring will be done so they achieve the target of how many follower you want in what period, and unfollow those who did not follow in return, say, in 7 days. so knowing this, its a time consuming. these marketers doing it full time so its worth it to pay them to do it. on my 7 days experience of follow and unfollow 500 people, i get only 200 quality followers in return (quality means, in the same niche, individual, have interactions), and it took most of my time in the office.
