Enlisting a book discovery service promoting cheap or free eBooks to a subscriber list – or helping you to boost your own social media efforts – is one way to get readers, reviews, more social networking, and a kick-start to your book sales.

Whatever your preferred means of promoting your title, free and bargain book listings could be one way to kick-start your book promotions. As with any promotion, it’s up to you as the author – or whoever is in charge of the book promotion – to vet providers and make the right decisions regarding where to spend money and how to position your book. In other words, we’re not specifically recommending this approach, but if you’re inclined to give this promotion tactic a go to aid in book discovery of your title, here’s a list to set you on your way.

The idea is simple enough: These services provide access to their lists, typically by email, with titles vetted by their established processes. Most are up front with their subscribers that these promotions are advertorials, in conjunction with various other criteria: some services boast of stringent editorial input, meaning every title is approved by an editorial staff before being included, while others have much softer criteria. This means that, should your title not make the cut at one service, there are others that will probably carry your title.

Here are 10 services that cater to independent authors:
