"No one wants to pay for distraction, but they will pay if it's packaged as help." (me)
How help is defined is tricky. It depends on the client/customer's wants.
If your prospective customer wants to escape their environment, then consider if you, the independent author have the skills, resources, and experience packaged in your book to help.
If your book is the solution, then show them how it can get what they want. In this case, adventure, exotic destination, and as a bonus, a mental place where they will experience something new.
If your book doesn't qualify to assist, then recommend one that can and sell it to them.
Note: selling is an exchange of goods and services for currency. (Currency could be signing up for your newsletter because they value your judgment.)
You can increase your market to gain their trust and sell them what they want another time.
This marketing mix relies on the SAVE* strategy. When marketing your book, consider a promotion campaign that features Solution, Access, Value, and Education.
S = solution - show us how your product helps us solve our problem.
A = access - consider how your readers decide to make purchases and provide product info along those channels. Remember, following customers around a store doesn't work - so don't cyberstalk your prospective buyer either. Think about affiliate marketing - advertisers want to appear where they know prospects are receptive to their solution. It's soft promotion because there's no one aggravating them, allowing the candidate to seek out information for themselves.
V = value - ask how does this product (book) benefit your reader. Every book is not for everyone. So first find out who reads your type of books - and then share with them how your book fits their desires.
E = education knowing who your readers are allows you to share information on topics they enjoy. If your book is a romance - then romance readers would be thrilled to learn the latest - like a romance industry gossip website will bring them to you - and you can engage and build a community around mutual interests.
And this how you can position your book, product/service, in a way that helps them help you.
