Do you think blog tours help sell books?Yes.
IF the stops along the blog tour have loyal readers who trust the judgment of the reviewer and the reviewer gives you a positive, well-written review. AND if there are easy links from the blog stop to a place to purchase the book online.
Anyone done a blog tour that wants to chime in?
Related to blog tours, any type of internet promo is usually a good thing. For example, Traitor by Sandra Grey has a post over on the LDS Fiction blog. As of this posting, that book had the most positive comments about it. I bought it and put it on my Summer Book Trek Reading list for that very reason. (Although I haven't read it yet.)
