The back cover has a blurb, and since I have no pretty picture to tempt a reviewer to pick up my book in front of the 20,000 other books on the "to read" list, I made sure I mentioned my awards first thing, even before the short description of the story.
ARCs are a necessary evil. They aren't "pretty" yet. They cost more to produce than the final published version, and I have to ship them FedEx to some places for speed and to prove something to them. (Don't ask me what.) In addition, the odds against getting a review from these places is so stacked against a small publisher that I don't expect to get anything out of the exercise. However, lightning might strike, so I do it.
In fact, if I had a bigger list of pre-pub reviewers who would look at my work, I'd add them to the list. Third-party recommendations are the only way I'll ever grow my audience.
