ONE BOOK GIVES READERS MANY REASONS TO PARTICIPATE.

Rebecca Yarros’s Fourth Wing gives readers more to share than a review. Reactions, character rankings, theories, quizzes, and reading rituals turn the same book into different kinds of reader-generated content.

Overview

  • Fourth Wing illustrates seven reader participation formats, including reactions, theories, recommendations, quizzes, and rituals.

  • Independent, commissioned, and affiliate content represent different relationships that can overlap.

  • Brands can adapt these entry points to customer experiences, preferences, uses, and routines.

  • Clear prompts, contributor credit, and room for honest opinions help make participation easier.

  • Measure contributor diversity, repeat participation, member interactions, and tracked business outcomes over time.

That is part of what makes BookTok marketing so interesting for brands. For brands, the useful question is what gives customers a reason to contribute their own perspective. This article examines those participation formats and how they can inform a community-led marketing strategy.

First, What Is BookTok?

BookTok is TikTok’s reader community, where people share recommendations, reviews, reactions, reading updates, and discussions. In a 2022 Publishers Association survey of more than 2,000 people aged 16–25, 59% said BookTok or book influencers had helped them discover a passion for reading. 

BookTok marketing operates within that wider reader conversation. Publishers can contribute to it, while readers also create content independently.

These figures show BookTok's strong connection to book discovery and purchasing, although they do not prove TikTok caused every sale. For Fourth Wing that won TikTok's international book award in 2024, with Rebecca Yarros crediting the BookTok community when accepting the recognition.

Seven Ways Readers Create Readers Generated Content Around One Book

Readers can participate before, during, and after finishing a book. These seven formats show how different interests and levels of involvement produce different content:

1. The Reaction

A reader might record a facial expression, emotional update, or quick reaction after finishing a chapter. The product provides the emotional trigger, while the reader supplies the content. These posts work because other readers recognize the feeling or become curious about what caused it.

2. The Reading Update

A reading update documents progress before the final verdict. Wolfgang Tischer of Literaturcafé, for example, began a TikTok challenge around reading Fourth Wing and discussing his experience.

Follow-up posts can track changing opinions and give other readers opportunities to respond along the way.

3. Character Preferences

Character rankings, favorite-character edits, and disagreements let readers express their taste. Choosing a favorite can also signal how someone relates to the story, giving other readers a starting point for agreement or debate.

4. The Theory

Theory posts connect clues and propose explanations that other readers can challenge or expand. Unresolved questions give the discussion room to continue through replies, counterarguments, and later reading updates.

5. The Recommendation

“What should I read after Fourth Wing?” turns the book into a reference point for discovering other titles. Readers can recommend stories with similar tropes, pacing, or emotional appeal, keeping Fourth Wing part of the conversation even when another book is featured.

6. The Quiz and Participation Post

A Fourth Wing quiz lets readers test their knowledge and compare answers. Pearl’s Bookshelf illustrates the format through questions viewers can answer while watching.

A short quiz asks less of participants than a detailed review or theory, giving readers another way to join the conversation.

7. Reading Rituals

Reader content also includes annotating, arranging shelves, collecting editions, preparing themed drinks, and visiting bookstores. These broader BookTok rituals make the reading experience itself a subject for content, beyond discussing the plot.

Community Activity Is Different From a Sponsored Campaign

TikTok book promotion can include independent reader posts, commissioned creator content, and affiliate recommendations. These relationships can overlap, so identify the commercial arrangement before interpreting a post as evidence of community participation.

Independent fan content

The reader posts without a brand commission or affiliate incentive. The publisher does not direct the message.

Commissioned creator content

A publisher or brand pays for content and agrees on deliverables. The creator may also earn affiliate commission.

Affiliate content

The creator can earn commission from purchases through a link or shop feature, whether or not a separate production fee is paid.

What Brands Can Learn From Fourth Wing

For community marketing, these formats suggest different entry points: sharing an experience, comparing preferences, demonstrating a use, or documenting a ritual. The following category examples illustrate possible executions, rather than evidence of an established community.

Beauty: One Product, Different Routines

Suppose the product is a cleanser. One creator shares a five-minute morning routine, another shows what they use after heavy makeup, while others discuss sensitive skin, compare routines, or post a product-empty update.

Tap to play

The product stays the same, but the context keeps changing. Each angle gives the audience a different reason to watch, relate, and respond.

Fashion: One Piece, Different Interpretations

A single t-shirt can inspire minimal styling, office looks, party outfits, seasonal layering, styling reactions, outfit rankings, and recreated community looks. 

Tap to play

Each format gives customers a different way to express their personal taste while keeping the same product at the center.

Food: Turn Consumption Into a Ritual

A beverage can become a morning routine, recipe, taste test, flavor ranking, seasonal variation, “how I make mine” video, or hosting ritual. Each format lets customers show how the same product fits into their own lives.

Tap to play

That is the connection to community marketing. The product provides a shared object, while the community provides different interpretations.

How Brands Can Support Participation

Brands cannot force a community to behave like BookTok, but they can reduce the friction around participation.

Learn the community's language first

Observe how customers naturally describe the product, including recurring phrases, common use cases, jokes, and preferences within the community. These signals often provide stronger content prompts than corporate campaign language.

Work with people who already use the product

Prioritize creators with relevant category experience and a credible connection to the audience. Existing users can offer useful insights, but evaluate their communication skills and content fit alongside their familiarity with the product.

Give people prompts

Give people one answerable prompt, such as “Which would you choose?”, “Show us how you use yours,” or “Rank your favorites.” Match the effort required to the audience’s willingness to participate.

Credit contributors

When customers create something useful, acknowledge and credit their contributions by reposting with permission or referencing their ideas in future content. Participation feels more meaningful when customers can see their contributions become part of the wider community.

Let people disagree

Allow different preferences and honest criticism. Use recurring feedback to inform future content instead of requiring every contribution to reach a positive verdict.

Measure the Community, Not Only the Biggest Post

Community-led marketing requires different performance questions because a single viral video does not tell you whether a community exists. You have to track:

Signal

What It Tells You

Unique contributors

How many different people are creating

Repeat contributors

Whether people return to participate again

Substantive comments and replies

Whether people ask questions, share experiences, or respond to specific points

Member-to-member interactions

Whether members respond to one another

Referral traffic

Whether discussion moves people toward the brand

Tracked purchases

Sales recorded through defined links, codes, or attribution settings

Track these signals over a consistent period and distinguish independent, commissioned, and affiliate contributions. Twenty posts from one paid creator measure output; posts from multiple independent customers indicate broader participation. Neither count alone establishes an active community.

The Goal Is More Ways to Participate

Start with a customer behavior that already exists, then create a prompt that makes contributing easier. Evaluate whether different people participate, return, and respond to one another over time. 

That is the principle brands can apply to community-led marketing. Masterhooks can build UGC programs around different customer behaviors, creator formats, and participation prompts, giving creators and customers multiple reasons to keep talking about the same product.
