It's interesting. I've wondered if blog tours really work. And yes, the numbers don't lie, but they also don't tell the whole story. You got Mary's name out a LOT. The sales may come down the road. People might remember the book and pick it up in a store later, so 11 books isn't a final count. Also, blog tours are lots of work but nothing compared to driving to a bookstore for a signing, or buying ads, or the hustling you have to do to try and get publicity in a newspaper or magazine, so yes, work, but be careful what you compare it to. Thanks for the post.
