For many authors, the word review immediately brings to mind Amazon ratings and reader comments. While those reviews are certainly important, they represent only one piece of a much larger review ecosystem. Understanding the different types of reviews can help authors build credibility, reach new readers, and create a stronger book marketing strategy.

During our recent Sunbury Press marketing webinar on book reviews, we discussed how not all reviews serve the same purpose. Some are designed to influence readers, while others help booksellers, librarians, media outlets, and industry professionals discover new titles.

Reader Reviews

Reader reviews are the reviews most authors are familiar with. These appear on platforms such as Amazon, Goodreads, Barnes & Noble, and other retailer websites.

These reviews provide social proof for potential buyers. When readers see dozens of positive reviews, they are often more confident in making a purchase. Reader reviews can also influence retailer algorithms, helping books gain additional visibility.

Best use:

• Building trust with readers
• Increasing online visibility
• Supporting retailer sales pages

Editorial Reviews

Editorial reviews are professional reviews written by industry experts, journalists, or review organizations. Unlike reader reviews, these are typically written by experienced reviewers who evaluate books based on established criteria.

Many authors use editorial reviews as endorsements on book covers, websites, press releases, and marketing materials.

Best use:

• Adding credibility
• Providing professional validation
• Creating marketing content and promotional quotes

Trade Reviews

Trade reviews are a specialized type of editorial review published in industry publications such as Kirkus Reviews and Publishers Weekly. These reviews are often read by booksellers, librarians, distributors, and publishing professionals.

A strong trade review can help a book gain industry attention long before readers discover it.

Best use:

• Reaching librarians and booksellers
• Supporting bookstore and library placement
• Building industry credibility

Blogger and Influencer Reviews

Book bloggers, BookTubers, BookTok creators, podcasters, and social media influencers have become increasingly important in the book world.

These reviews often feel more personal and conversational than traditional reviews. Because influencers typically build loyal audiences around specific genres, their recommendations can have a significant impact on book discovery.

Best use:

• Reaching niche audiences
• Creating buzz around a launch
• Expanding social media visibility

Media Reviews and Features

Newspapers, magazines, local media outlets, podcasts, and online publications often review books or feature authors in interviews and articles.

While these reviews may not always directly drive sales, they can significantly increase visibility and establish an author's reputation.

Best use:

• Publicity and awareness
• Local and regional promotion
• Establishing author authority

Endorsements vs. Reviews

It's also important to distinguish between endorsements and reviews.

An endorsement is typically a short statement from another author, industry expert, or recognized professional. While not technically a review, endorsements can be just as valuable in marketing because they provide instant credibility.

Think of endorsements as recommendations and reviews as evaluations.

Which Reviews Matter Most?

The truth is that no single type of review is "best."

A successful book marketing strategy often includes a combination of:

• Reader reviews for social proof
• Editorial reviews for credibility
• Trade reviews for industry recognition
• Influencer reviews for audience engagement
• Media coverage for visibility

Each type of review serves a different purpose, and together they help create a well-rounded foundation for long-term book promotion.

Final Thoughts

Reviews are about far more than collecting five-star ratings. They help readers discover books, provide credibility to industry professionals, and give authors valuable tools for ongoing promotion.

Whether you're seeking reader feedback, pursuing a professional editorial review, or reaching out to book bloggers and podcasters, every review contributes to your book's story and visibility. The key is understanding how each type fits into your overall marketing strategy, and using them together to maximize your book's reach.
