Yesterday's blog post about idiot book promotion prompted a question about how would you solicit reviews without sounding obnoxious.
Here are some bullet points:
1. Remember that a blogger is interested in building his/her readership. A sentence that shows you've actually looked at the blog and have a clue about the readers is step one.
Then you say "I think your readers will find value in/enjoy/benefit from" TITLE because it does this/says that.
What's implied is that the recipient will discuss the book on his/her blog.
2. If you're sending to non-bloggers: "A lot of people ask me how they can support writers and one of the best ways is to leave a review on Amazon or GoodReads."
3. If you're sending to a college newsletter or some other information source to which you have a connection: You say "Hi I'm Felix Buttonweezer (Class of 06) and my first book will be published by HotStuffPress in September 2017. The book is inspired by my college roommate who kept a 10 foot python in the closet, which was all good and well till someone left the door open."
In other words, you mention the connection of both you and the novel to the audience.
This goes for the local newspaper too. They're always looking for Local Person Makes Good kind of stories.
Notice that you aren't asking for a review as such.
You're stressing the value of your book to the recipient's audience.
In other words you're answering the "why should I care" question without it being asked.
