BookAuth vs. BookSirens: Don't pay a per-reader fee. Build your own audience.
BookSirens is a powerful, niche platform designed specifically to help authors find new reviewers. However, their standard pricing model charges you a setup fee just to list your book, plus a fee for every reader they find. If you want 100 reviews, you could easily spend hundreds of dollars on a single launch. Alternatively, you can pay an annual subscription for their subscription plan—but you still don't get a website, a direct sales storefront, or an email marketing system. BookAuth offers a fundamentally different approach. We give you unlimited ARC distribution built into an ecosystem that actually helps you sell the book once it launches.
The Big Idea
Paying a per-reader fee makes sense for your very first book when you have zero audience. But as your career grows, the 'pay-per-reader' model becomes a severe tax on your success. Instead of renting an audience from BookSirens, BookAuth is designed to help you build and own your audience. We provide the complete infrastructure: you distribute your ARCs natively through BookAuth, build your email list using our enterprise CRM, and sell your backlist directly to those readers through your custom storefront. Instead of managing a fragmented stack of expensive tools, you manage your entire author career for a flat BookAuth Pro subscription.

Who should choose which?
Every author's needs are different. Here is our objective recommendation based on your publishing goals.
Choose BookAuth if:
- ✦Authors who already have an audience (or are actively building one) and want to manage their own ARC team without paying per reader.
- ✦Authors looking for a unified business platform (Website, ARCs, Storefront, Emails) rather than fragmented software.
- ✦Authors who want to transition from renting audiences to owning their email lists.
Choose BookSirens if:
- ✦Debut authors who have absolutely zero audience and are willing to pay a per-reader fee to generate their first 20 Amazon reviews.
- ✦Authors who exclusively write in highly specific romance/thriller niches that dominate the BookSirens influencer pool.
Frequently Asked Questions
Should I use BookSirens or BookAuth for my ARCs?
It depends on your audience size. If you are a debut author with zero followers, BookSirens is excellent because you can pay them a per-reader fee to access their pre-existing network of reviewers. However, if you already have a newsletter or social media following, you should not be paying a per-reader tax. BookAuth gives you the software to manage unlimited ARCs to your own street team for a flat BookAuth Pro subscription, alongside your website and storefront.
Can I sell my book on BookSirens?
No. BookSirens is strictly an Advance Reader Copy (ARC) platform. They do not offer retail storefronts, e-commerce, or author websites. If you want to sell your books directly to readers, you will need a platform like BookAuth.
Does BookSirens let me keep the email addresses of the reviewers?
Yes, they offer an opt-in feature where readers can choose to join your mailing list. However, because BookSirens does not have a native email marketing system, you must export those emails as a CSV file and pay for a separate third-party service (like MailerLite or Mailchimp) to actually email them.
