(1) Sign up for a Twitter account, upload a photo, write a short bio that includes you’re an author, and link to your website. Make your bio intriguing.
(2) Upload a custom background, preferably with written-out links to your other web presences (links will not be live) or pictures of your books. Something that doesn’t make you look like another cookie-cutter business author.
(3) Take five minutes to learn the Twitter lingo and bookmark this page for future reference. Everyone has to look things up occasionally.
(4) Follow 20 Twitter handles: five people you know personally, five gurus or leaders in your field, five media outlets or journalists you follow regularly, and five brands you respect. This variety is important to understand the Twitter eco-system.
(5) Sign up for a Hootsuite account to schedule five tweets throughout the day: one tweet promoting you or your book, two retweets, and two articles to share with your followers. Remember to schedule each tweet at least one hour apart.
(7) Check for @ replies at the end of every day and respond to people as appropriate.
(12) Build on what you know.
