Reviews can influence what happens after a reader becomes interested in your book.
A reader may click because the cover, genre, or description catches their attention and then look at ratings and reviews before deciding whether to download or purchase.
The number of reviews is not the only factor that matters, and books with relatively few reviews can still attract readers. Review quality, overall presentation, price, description, and reader interest all contribute to the decision.
The Fussy Librarian does not guarantee better results based on any particular review count.
