NetGalley vs BookSirens

By the WriteLoom editorial teamUpdated 2026-09-02
Key facts
  • NetGalley list price runs several hundred dollars per title per month; co-op listings cost less.
  • BookSirens charges a small per-download fee, typically under $2, with a low setup cost.
  • NetGalley's audience includes librarians, booksellers, and trade reviewers.
  • BookSirens readers are genre fiction readers who post to Amazon and Goodreads.
  • BookSirens reports which readers actually posted; NetGalley reports feedback within its own system.
Direct answer

NetGalley reaches librarians, booksellers, and trade reviewers, which matters for nonfiction, literary fiction, and anything hoping for institutional pickup. BookSirens costs a fraction as much and reaches genre readers who post retail reviews. For most indie fiction, BookSirens is the better value; NetGalley is a positioning spend.

Chapter i·Why it matters

Authors often buy NetGalley expecting retail reviews and get feedback from readers who never post to Amazon. That is not a defect, it is what the platform is for. Matching the platform to the review you actually need, retail social proof versus institutional credibility, saves several hundred dollars and a launch cycle.

Chapter ii·What to include

  • What kind of review you need: retail star count or trade credibility.
  • Cost per posted review, estimated for both before you commit.
  • Co-op NetGalley listings through a publisher group, which cut the price sharply.
  • Genre fit, since BookSirens skews toward commercial fiction.
  • Whether library or bookstore buyers are realistic targets for this title.
  • Whether your budget would do more as a promo stack instead.

Chapter iii·Example

An indie fantasy author spent $450 on a NetGalley co-op listing and got 14 retail reviews. The next book she spent $110 on BookSirens and got 38, and put the difference into a promo stack.
