Do NetGalley members have to cross-post reviews to Amazon, Barnes & Noble, GoodReads, their blog, etc.?

Members aren’t required to cross-post their reviews, but many reviewers do. If a reviewer is active on consumer websites, it builds their own audience and improves the likelihood that they will be approved to read titles that they request. Reviewers know that publishers and authors value reviews on multiple platforms and that building an audience means posting on multiple bookish platforms. That being said, many NetGalley members are requesting and reading titles to make purchasing decisions for a library, school, or bookstore. Those members might not leave reviews that they cross-post to consumer websites, although they can still provide valuable feedback about your title.
