If you're an author lucky enough to be published by a publisher who can afford to fund a real book tour, then you'd be zipping around the country, making presentations, doing signings and just willing people to buy your book.
If you're an author, like me, published by a small publisher and your book's an e-book then none of the above is going to happen.
So you do a blog tour.
This is the first time I've done one so I thought I'd let you know how I get on. First of all - here's the link of the host site: http://thesepaperworldsbt.blogspot.pt/ where my schedule is. As you can see, I have several slots each with a theme. Today's theme is "Ten Tips for Aspiring Authors". Take a look at what I wrote: http://theclockworkofthebooks.blogspot.pt/.
Let me know in the comments if you have any queries.
