which tips are good even if you don't have any followers, especially this ones of that post:
6. Select the initial characters of each tweet carefully
The “lead-in” of each tweet appears to be important for SEO as it will determine what appears in the tweet’s title tag when it shows up as a search result on Google. Approximately 42 characters are factored into each tweet’s title tag, including the account name, as well as the initial characters of each tweet. Keep in mind that your full tweet and all its characters are still being indexed by major engines, though.
7. Write keyword-rich tweets if possible
Wherever possible, start your tweet with a primary keyword phrase to theme each message. Take advantage of any “active lingo” or buzz words as this will enable you to capitalize on timely searches on those terms. Of course, this doesn’t mean you should fill your tweets with buzz words at the expense of providing value to your followers! Rather, think carefully about which word choices will best convey your message and also allow you to leverage the real-time and long-term index relevance across the engines that continuously spider and index tweets.
