DIY Blog Tour: Post pit stop
Engage with readers by asking and answering questions. Even better, let the tour host know ahead of time that you'll be available during a certain hour of the day to do a rapid fire Q&A in the comment section. By making yourself accessible to readers, they are more likely to see you as a friend. Friends by other friends' books.
Another way to build buzz is to quote blog comments on your social network sites. Scan the comments for anything poignant, witty, or just plain fun. Be sure to give credit to the commenter, link back to the tour stop, and use the hash tag. Readers will remember that you cared enough about what they said to share it. Plus, who doesn't like getting a little Twitter love from an author?
Of course, like everything else, a little goes a long way. Don't try to quote everyone or your feed will turn into one big spam trap.
