The launch posts are usually the easy part: a cover reveal, a publication-day announcement, a thank-you to early readers. The harder question comes a few weeks later, once those obvious posts are used up and the book is still there, still needing readers, but with nothing new to announce. This is where a lot of author accounts either go quiet or start repeating the same buy-link post, and both responses tend to reduce how much anyone engages.
This guide sets out a small, reusable set of content pillars that work for an already-published book, with concrete post ideas under each one, and a simple planner for rotating between them so posting after launch doesn’t depend on constant new inspiration. See the hub for [book sales & growth](/resources/book-sales-growth) guides more broadly, and the related question of [what should authors post on social media?](/resources/book-marketing/what-should-authors-post-on-social-media) for the general version of this question.
Why does post-launch content feel harder?
Launch content has a built-in reason to post: something is genuinely happening. Once that window closes, the book itself hasn’t changed, so it can feel like there is nothing left to say. The actual problem is usually that the account has only ever had one message — "the book exists, buy it" — rather than a set of angles to draw on. Content pillars solve that by giving you several legitimate, non-repetitive things to talk about.
Pillar one: the book itself
This pillar stays close to the book without repeating the same purchase link.
- A short excerpt, where your rights and platform terms allow it
- A genuine reader review, quoted with credit
- A theme the book explores, discussed in a paragraph
- A character introduction or the idea behind a key scene
- A behind-the-scenes note on a decision you made while writing it
Pillar three: the reader
This pillar treats social media as a conversation rather than a broadcast channel.
- A genuine question related to your book’s themes
- Asking for recommendations of similar books or comparable authors
- Responding publicly (with permission) to a reader’s comment or photo
- Starting a discussion around a topic your community cares about
Pillar four: the world or subject
For fiction, this means the setting, period, genre conventions or research that shaped the story. For non-fiction, it means the ideas, questions or frameworks the book is built on, discussed on their own terms rather than as an advert for the book.
| Fiction | Non-fiction |
|---|---|
| A detail about the historical or fictional setting | A useful idea or framework from the book, given away freely |
| A genre theme or trope you deliberately used or subverted | A question your book helps readers answer |
| Research that shaped a scene or character | A short case example that illustrates the book’s core idea |
Pillar five: proof and activity
This pillar only works if it is real. A genuine review, a reader photo shared with permission, a bookshop stocking the title, a milestone that actually happened — these build credibility. Inventing activity or exaggerating small events damages trust when readers notice, and some will.
Do
- Share a genuine review with the reviewer’s permission and credit
- Mention a real milestone, however modest, without inflating it
- Post a reader photo only with clear permission
Avoid
- Imply demand or momentum that isn’t real
- Present a single sale or comment as evidence of a "trend"
- Repost the same review repeatedly as if it were new
Is there a fixed ratio between pillars?
No. You may see rules such as an "80/20" content split presented as a scientific law; it isn’t one, and treating it that way can make you force content that doesn’t fit your book or voice. Use the pillars as a rotating menu, weighted towards whichever ones genuinely suit your platform, genre and the time you actually have available.

A useful next step once the pillars feel repetitive is to check whether the underlying ongoing marketing rhythm needs revisiting, not just the individual posts.
Common mistakes
- Posting only launch-style announcements indefinitely. A cover reveal and a buy link can only be posted so many times before they stop landing.
- Treating every post as a direct sales pitch. Readers tend to disengage from accounts that only ever ask them to buy something.
- Inventing proof or exaggerating small milestones. This damages trust badly if readers notice, and some will.
- Chasing a rigid content ratio. A fixed formula can force content that doesn’t suit your genre, voice or platform.
- Posting on every available platform out of obligation. A smaller, consistent presence on one or two platforms usually beats a thin presence everywhere.
Frequently asked questions
How often should I post after launch?
There is no universal frequency that suits every author or platform. A sustainable rhythm you can keep up matters more than a specific number of posts per week.
Can I keep sharing the same review?
Occasionally, yes, but repeating it too often reads as padding. Rotate it with other pillars rather than relying on it as a default post.
Do I need to post on every platform?
No. Choosing one or two platforms that suit your readers and your capacity is usually more sustainable than spreading thinly across all of them.
What if I genuinely have nothing new to say?
That is exactly what the pillars are for: the subject and reader pillars, in particular, do not depend on new news about the book itself.
