Have you ever done a blog tour?

I decided to hire someone to help me set up a blog tour and I’m nervously awaiting the start of it not knowing what to expect. However, although I maintain a blog, I have very little clue for how to set up a tour. It seemed like a lot of ground work would need to be done and, quite frankly, with my crazy schedule, I was willing to hire someone to do it for me. Plus, I figure it will get me exposure with some new blogs.

I actually was surprised at the different types of tours available. You can get tours that focus reviews, interviews, excerpts, giveaways and articles. I selected one that is a mix so I can get my feet wet with everything.

I’m curious if any other writers have done a blog tour. How long did it last? Was it useful? What did it involve? This is all new to me so let me know your experiences.
