  • Both report posted reviews, which makes cost per review comparable.
Direct answer

Hidden Gems curates: you pay per campaign and they match your book to reviewers in its genre from their own list. BookSprout is self-serve and cheaper, relying on its readers to find you. Hidden Gems costs more per campaign and usually converts better on genre fit.

Chapter i·Why it matters

The difference is who does the matching. BookSprout's cost advantage disappears if your book sits in a browsing feed and attracts readers outside its genre, because mismatched readers leave low reviews. Paying for curation is buying against that risk, and whether it is worth it depends on how well your genre is served on the cheaper platform.

Chapter ii·What to include

  • Cost per posted review, calculated for both after one campaign each.
  • Genre fit and how much matching each service actually does.
  • Review quality, not just count: are they from readers of your category?
  • Volume needs, since Hidden Gems campaigns are sized in advance.
  • Timing, since curated campaigns book out further ahead.
  • A test of both on consecutive releases before committing.

Chapter iii·Example

An author ran BookSprout on book one for $25 and Hidden Gems on book two for $180. Book one got 29 reviews at 3.9 average; book two got 41 at 4.4, from readers who clearly read the genre.
