Social Media Marketing
A sustainable content plan and designed assets for the platforms where your readers actually are — not all of them.
- Price From $640 per month, from
- Typical timeline Monthly, three-month minimum
The most useful thing we do here is talk most authors out of most platforms.
Being present everywhere means being weak everywhere, and authors who try it burn out within a couple of months. We start by working out where your readers genuinely are — which is category-dependent and often surprising — and then commit to one or two places properly.
From there we build a content plan you can actually sustain. That means a realistic posting rhythm rather than an aspirational one, and a mix that is not relentless promotion: process, craft, what you are reading, the small specific things about writing that readers find genuinely interesting. Books sold through social media are almost always sold by the author being worth following, not by the book being advertised.
Each month you receive designed assets built from your brand kit, a scheduled calendar with captions drafted, and a short report on what performed and what to do more of. Everything is yours to edit — most authors adjust captions to sound more like themselves, which is exactly right.
Engagement stays with you. Replies from real readers should come from the actual author, and outsourcing that is both obvious and counterproductive.

What we need from you
Requirements
Having these ready before we start is what keeps the timeline honest.
- Existing accounts, or willingness to create them
- A brand kit or at least your cover files and author photograph
- Some willingness to engage personally — replies should come from you
Production timelines are estimates. Actual schedules vary with manuscript length, revision rounds, author response time and third-party retailer processing.

It depends entirely on category. Visual, community-driven platforms suit some genres; text and video platforms suit others; business authors often do better on professional networks. We will make a specific recommendation for your book rather than a general one.
We can schedule content, but we recommend you handle replies and comments yourself. Readers can tell when a person is not there, and the value of social media for authors is precisely that a person is.
No. Plenty of authors build a readership entirely through text and images. Video helps in some categories, but forcing it when you hate it produces worse content than not doing it.
