The biggest rule for Twitter and the trick to all marketing is simple: Be interesting and people will be interested in you.

FOLLOWERS will only book you if they are INTERESTED in you.
They will only be INTERESTED if they are FOLLOWING you.
They will only FOLLOW you if they find you INTERESTING.
They will find out if you are INTERESTING by reading your Twitter stream.
COMING IN FOR A LANDING...
Most people really just want to know who you are and why they should follow you. That’s why you should use a Customized Background to give people a QUICK overview of who you are and what they can expect if they follow you. The goal, after all, is to get the follower now and make the sale later.

WHERE’S THE BEEF?
We all know first impressions are crucial, which is why you gain new followers and build credibility through creative content. Gertrude Stein once joked about Los Angeles that there was “no there there.” People need a unique reason to follow you, so give them a “there” to visit by providing clever content. This will help stand out against the white noise of other Tweeters, as well as dreaded spammers.
COUNT TO 20
When someone goes to your Twitter homepage, the first thing they see is your last 20 tweets, also known as your recent Twitter stream. Hence, your last 20 Tweets say a lot and give you 20 chances to sell someone on following you. Make sure your Twitter stream exudes value and gives potential fans a glimpse of what they will get as a follower.

NO GREEN EGGS WITH SPAM
Give your Twitter stream variety in thought and language. Don’t just brag about yourself or promote your site. If you do, you’ll quickly discover no one cares. Never lose sight of the fact that your goal is to provide VALUE to your target audience. This will help you get “re-tweets,” where people tell their friends about you. Good word of mouth, as we know, is priceless.
