Blog tours can help. Sometimes publishers will put them together for authors, and sometimes authors will put them together for themselves, but this time, my publisher, Covenant Communications, put together a blog tour for Betrayed. The tour is on day 2, and so far I've seen three great advantages: I've received some dream-come-true reviews which have been posted on important sites like Amazon and Goodreads; tweets about my book have surfaced through Twitter; and I am finding new readers.
The bad side of tours? They can be somewhat costly and time consuming to put together, and the cyber-world seems to always be changing, so it's hard to guage how many people are actually seeing it. But that's the case with every marketing tool. As for me, so far, so good--I'm happy with Betrayed's Blog Tour.
