Instagram rewards authors who use its different formats for different jobs: Reels for reach and discovery, carousels for teaching and converting existing followers, and Stories for ongoing, casual connection. Bookstagram, the book-focused corner of Instagram, has its own visual style and community norms, but the underlying platform mechanics work the same way for authors as for any other creator.
This is part of the Complete Guide to Social Media Marketing for Authors.
Reels are built for reach: Instagram's algorithm favors them for finding new viewers who don't already follow you, so they're your best tool for growing an audience. Content that works well as Reels includes trope hooks, emotional one-liners, worldbuilding clips, and character-focused content, often paired with trending audio.
Carousels (multi-image swipe-through posts) tend to convert existing followers better than Reels, since viewers slow down and read. They're well suited to educational or structured content: character guides, series recaps, trope breakdowns, or "what to expect" posts.
Stories are for casual, ongoing connection: drafting updates, cover reveal countdowns, polls, and quick check-ins. They're lower-effort and more frequent than feed posts, and they keep your account feeling active between bigger content pushes.
Live sessions work well for specific moments: launch-day Q&As, short readings, or real-time reader chats during release week.
Most successful author accounts organize their content around a small number of recurring themes, or "content pillars," rather than posting randomly. A common structure for fiction authors:
Having defined pillars also helps the algorithm (and your followers) understand what your account is about, which supports discoverability.
Research on author accounts commonly points to a range of four to seven posts per week as effective for growth, mixing several Reels with one or two carousels or static posts. That's more than many authors expect, but the volume matters less than sustainability: a cadence you can maintain through batching content in advance beats an ambitious schedule that burns you out within weeks.
When readers or bookstagrammers tag you in their own content, that's valuable user-generated content worth actively amplifying, not just passively acknowledging. Reshare it to your Stories while it's still gaining traction, leave a genuine comment (not just "thank you!"), and consider compiling reader quotes into a periodic "what readers are saying" carousel. This kind of active participation tends to be rewarded by the algorithm as a sign of a genuinely engaged account, not just a broadcasting one.
Instagram's hashtag algorithm, like TikTok's, has moved away from rewarding large hashtag counts. A smaller, more targeted set, mixing a broad discovery tag (#bookstagram), a reader-intent tag (#bookrecommendations, #bookreview), and a few genre-specific tags, tends to outperform stacking twenty or more generic tags.
Ready to Extend Your Reach?
Once you have organic Instagram content working, Entrada Publishing can help with paid promotion and broader online marketing to extend your reach.
Reels are built for reach and tend to be shown to people who don't already follow you, making them useful for growth. Carousels tend to convert existing followers better, since viewers slow down to read through them.
Research on author accounts commonly suggests four to seven posts per week for growth, though a consistent, sustainable cadence matters more than hitting an exact number.
A mix of book content, behind-the-scenes writing process, quotes or character content, and genre-appropriate lifestyle content, organized into a few recurring themes rather than posted randomly.
Fewer, more targeted hashtags tend to outperform large hashtag counts. A mix of one broad discovery tag, a reader-intent tag, and a few genre-specific tags is a reasonable starting point.
