I am guilty of thinking if you wanted to advertise on twitter you first needed followers to advertise to. This is not true. You can have your tweets available to everyone on twitter by using hashtags. Learn how reading this article. http://mporgsoft.com/blog/archives/157 What hashtags do you use when you tweet?
I mainly just tweet like 4 times in a row with a few of the top trends, or I'll go to one of my sites with the newest songs and type #newsoungs and proceed to name the artist and song... It usually gets you a few followers a day.
Just go to tweetstats and find the trending topics and post them and paste your link in between and believe me you can get a lot of hits!!!
Wouldn't Twitter consider that spam and shut down your account though? I always at least try and post "legitimate" tweets.
Also, the hits would not be quality if your spammed the current trending hashtag. Stay relevant with what your promoting.
Yeah, people who click a link that isn't what they think it is, would feel tricked and might resent your site.
