According to a 2025 BrightLocal study, 87% of individuals read online reviews before making purchases, and 79% trust these reviews as much as they trust a personal recommendation from friends or acquaintances.

Have you ever questioned why some books become bestsellers while others remain relatively forgotten? While writing quality may have something to do with it, sometimes beautifully crafted works don’t receive their due simply due to too few people talking about them – readers tend to be heavily influenced by what others say; when many reviews give an author positive ratings, it makes it more inviting and less risky to buy their book.

As a self marketer or book marketing services, it would be foolhardy for you to ignore this trend. Book marketing is now more about building trust than just writing great stories–success lies in mastering how to gain reviews and use social proof effectively for success.

What Are Book Reviews?

Book reviews provide readers with a critical evaluation of a book’s content, style and impact. They may be written by someone who has read the book themselves to provide their subjective thoughts about its quality, story or value. Reviews can often be found on online platforms like Amazon or Goodreads, as well as personal blogs, newspapers and magazines.

Book reviews cannot be understated in their significance for authors and books alike. An insightful review can increase visibility, increase sales, and attract more readers, often inspiring potential buyers to purchase the book if it aligns with their interests.

What Is Social Proof?

In psychological parlance, “social proof” refers to the psychological phenomenon in which people rely on others’ actions and opinions as guides for their behavior when uncertain of how best to proceed with something they have in mind. Within marketing contexts, this form can take the shape of reviews, testimonials, ratings, endorsements, or shares on social media that show others support a product or service being advertised or sold.

Social proof for books typically takes the form of customer ratings on platforms like Amazon and Goodreads, mentions in social media channels, and customer testimonials posted directly by readers themselves. The more positive feedback an author receives on these platforms, the higher its chance of drawing new readers in.

Why Readers Trust Reviews More Than Traditional Ads

Trust is at the foundation of every purchase decision. While traditional ads may grab people’s attention, reader reviews build it. People tire quickly of being sold to; they crave genuine opinions from real people.

• Surveys reveal that 92% of consumers overwhelmingly trust personal recommendations from strangers as more credible sources than brand ads.

• 7 of 10 consumers prefer social proof over product description when purchasing.

Your book ad may claim your book is captivating, but when readers rave that they stayed up all night reading pages, the ad becomes far more credible.

Reading books is often a time- and money-intensive endeavor.
