If you want more than the minimum, Focus on LinkedIn is the full treatment, updated for the platform as it works now.
Every client I work with asks the same question after their book is finished: “What should I be doing on LinkedIn?”
The honest answer is: less than you think.
I wrote an entire book about LinkedIn. Focus on LinkedIn sold 15,000 copies in three days on Kindle, and the dramatically expanded new edition covers everything from crisis management to Sales Navigator techniques. See why most book marketing fails. I know the platform. I also know that it has changed dramatically, and for most published authors, LinkedIn is a tool that should take about thirty minutes a week, not a second career.
The problem is that LinkedIn advice comes from two kinds of people: social media consultants who make money selling LinkedIn strategies, and people who spend hours a day on the platform and assume everyone should do the same. Neither perspective is useful for a published author whose book is the business asset and whose time is better spent on the work that generated the book in the first place.
Here is what actually works for authors on LinkedIn, stripped of everything that does not produce results.
Your Profile Is Your Book’s Landing Page
Most authors treat their LinkedIn profile as a resume. For more, see LinkedIn’s Algorithm Changed. Here’s What Actually Works in 2026.. It should be a book promotion page. For more, see viral posts on LinkedIn. The people who find you on LinkedIn after hearing about your book, seeing you speak, or getting a recommendation will look at your profile before they look at anything else. That profile needs to make one thing clear: you wrote a book, here is what it is about, and here is where to get it.
Your headline should mention the book or the expertise the book represents. Not your job title. “Author of [Book Title] | [What the Book Is About]” communicates more in one line than a corporate title ever will. Your About section should lead with the book, what it covers, who it is for, and what readers get from it. Include a link to purchase or to your website. This is not vanity. This is making it easy for interested people to find what they came looking for.
The Featured section is the most underused tool on LinkedIn for authors. Pin your book there. Link to your website, a sample chapter, a media appearance, or a booking page. The Featured section sits near the top of your profile and catches the eye before anything else. If you are a published author and your Featured section is empty, you are wasting the best real estate on the platform.
From the podcast
Mike O’Neil has worked LinkedIn since it had a hundred thousand users and wrote two books about profiles. He is blunt about which parts of yours carry the weight, on Leaders and Their Stories:
The area of your profile that matters the most obviously is your headline. That and your picture. Those are the two things. I don’t mean your body picture. I mean your mug.Everything below that is read only after somebody has already decided to look.
Post About What You Know, Not About LinkedIn
The biggest trap on LinkedIn is writing about LinkedIn. Posts about “how I grew my network” or “my journey to 10,000 followers” perform well on the platform because the algorithm rewards content about the platform itself. But those posts do nothing for your book or your business.
Post about the subject matter of your book. If you wrote a book about leadership, post about leadership. If you wrote a memoir about building a company, post about what you learned building the company. Every post should reinforce the same expertise and perspective that your book represents. The post is not the product. The book is the product. The post exists to remind people that you have something deeper to offer on this topic.
Keep posts short. Three to five paragraphs. One idea per post. No hashtag stuffing, no “agree?” at the end trying to bait comments, no fake vulnerability stories designed to game the algorithm. Write something that is worth reading on its own and that makes the reader think “this person knows what they are talking about, I should look at their book.”
Two to three posts per week is enough. More than that and you are spending time on LinkedIn that should be spent on revenue-generating work.
Are LinkedIn Comments Worth More Than Posts?
LinkedIn’s algorithm weighs comments more heavily than likes or shares. A post with fifty comments reaches significantly more people than a post with fifty likes. This means that engaging with other people’s content is as valuable as creating your own.
Spend ten minutes a day leaving substantive comments on posts in your area of expertise. Not “Great post!” but actual thoughts that add to the conversation. When you leave a thoughtful comment on a post that has high engagement, the people reading that thread see your name, your headline (which mentions your book), and your perspective. This is visibility that costs nothing and takes minutes.
This is also where your book becomes a networking tool. When someone posts about a topic your book covers, a comment that adds genuine value and comes from someone whose headline says “Author of [Book on That Topic]” is the most natural promotion possible. You are not pitching. You are contributing, and your book’s existence speaks for itself.
The One Article That Matters
LinkedIn’s article feature lets you publish long-form content directly on the platform. Most authors over-invest here, writing weekly articles that take hours and get minimal readership. The platform does not push articles the way it pushes posts, so the return on time invested is usually poor.
The exception: write one definitive article that serves as an extended introduction to your book’s core argument. Make it the best thing you have ever written on LinkedIn. Pin it to your Featured section. Link to it in conversations when people ask about the topic. This single article becomes a permanent asset that works for you without requiring ongoing effort.
That article should not be a chapter from your book. It should be a standalone piece that makes the reader think “if this is what they give away for free, the book must be exceptional.” Give real value. Hold nothing back. The article is not competing with your book. It is selling your book by demonstrating the quality of your thinking.
What Should Authors Not Waste Time on LinkedIn?
LinkedIn newsletters sound appealing but require consistent commitment to maintain subscribers. Unless you are prepared to publish weekly for a year, do not start one. A dead newsletter looks worse than no newsletter. For more on building a LinkedIn brand through content, hear Richard on Out of the Blank.
LinkedIn Live and audio events get low attendance for most users and require significant preparation for minimal return. Skip them unless you have an established audience that has specifically asked for live content.
LinkedIn groups are largely inactive and have been for years. Do not invest time building or participating in groups expecting meaningful engagement.
Posting every day is unnecessary and unsustainable for most authors. The consultants who recommend daily posting are building their brand on LinkedIn. You are building your brand on your book. Two to three posts per week is the sweet spot where you stay visible without LinkedIn becoming a second job.
The Thirty-Minute Weekly Routine
Here is what a realistic, effective LinkedIn strategy looks like for a published author.
Sunday: write two to three short posts for the week, each one about a topic your book covers. Schedule them or save as drafts. Fifteen minutes.
Daily: spend five minutes leaving one or two substantive comments on posts in your area of expertise. Five minutes.
Monthly: check that your profile, headline, Featured section, and About section are current. Update if anything has changed. Five minutes.
That is it. Thirty minutes of actual work per week, plus five minutes a day of commenting. Everything else is optional and should only be added if you have evidence it is producing results for your specific situation.
Your Book Is the Real Platform
LinkedIn is a distribution channel, not a destination. The book is the destination. Every minute you spend on LinkedIn should serve the book, either by driving people toward it or by reinforcing the expertise it represents. If your LinkedIn activity is not doing one of those two things, it is not working for you regardless of how many likes your posts get.
For authors ready to write the book that becomes the foundation of their professional platform, start with a conversation about your book and your goals. You can find current ghostwriting pricing on the ghostwriting page. For fiction writers building their craft, my AI-Enhanced Book Promotion Handbook covers marketing strategy across every platform, including how to use LinkedIn without letting it consume your writing time.
