The best LinkedIn post ideas for a consultant, coach or advisor are already written on the business's website.
The service page says what an engagement covers and who it is for.
The FAQ holds the questions clients ask before they buy.
The process page is a sequence of decisions.
The reviews page is proof with a story behind it.
The about page carries a point of view.
That matters on LinkedIn more than anywhere else, because the LinkedIn reader is a peer or a buyer, and the question in their head is not "do I like this person" but "does this person know the work".
A post built from a page you wrote with care answers that question without you performing.
Below are 20 post ideas grouped by the page they come from, with the first line, the body and the last line for each.
They are written for consultants, coaches, financial advisors, accountants, HR professionals and anyone else whose business is judgment.
If you post on more than LinkedIn, the broader list is 47 social media content ideas for small business.
What to post on LinkedIn, and what to leave out
A LinkedIn post from an expertise business has one job: show the judgment a client would be paying for.
That rules a few things in and a few things out.
In: a specific situation and what you would do about it, a distinction clients get wrong, a boundary you hold, a step in your process and why it exists, a result with the reasoning that produced it.
Out: motivation, announcements about yourself with no lesson attached, engagement questions with no stake in the answer, and "DM me" as a last line.
The shape that works is simple.
One line that states the point.
Three to eight short lines that earn it.
One line at the end that says what happens next, or asks a question worth a real answer.
Write for the reader who will never comment, because that is the reader who books the call.
From your service page: four posts
1. What the first engagement actually covers.
First line: the question a nervous first client asks.
Body: the session in order, one line per part, from the service page.
Last line: what to bring, and where to book.
2. Who this is for, and who should not hire me.
First line: "Half the people who contact me should not hire me. Here is how to tell."
Body: two lines for the right fit, two for the wrong fit, one on what to do instead.
Last line: the fit question, put back to the reader.
This is the strongest LinkedIn post an advisor can write, because fit is the thing every prospect is silently working out.
3. What is included, and what is not.
First line: the thing people assume is included and is not.
Body: the inclusions as a short list, the exclusions said plainly.
Last line: the page that carries the detail.
Saying no is what makes the yes credible.
4. How long it takes, and what slows it down.
First line: the honest timeline.
Body: each stage with its duration and the one thing that stretches it.
Last line: how to start the clock.
From your FAQ: four posts
5. The question everyone asks first, answered in public.
First line: the question, verbatim.
Body: the answer from the FAQ, in the same words you would use on a call.
Last line: the second question it usually leads to.
6. The question nobody asks until it is too late.
First line: "Nobody asks me this until it has already cost them."
Body: the question, why it matters, what to check before deciding.
Last line: the check, as one sentence they can do today.
7. What that word on the proposal means.
First line: the term, in quotes.
Body: the plain definition, then why it changes the price, the timeline or the outcome.
Last line: the next term, next week.
Advisors, accountants and lawyers can run this one for a year.
8. Yes, we do that. No, we do not. Here is why.
First line: one thing you refuse to do.
Body: the reason, and what the refusal protects for the client.
Last line: the thing you do instead.
It costs you something to say, which is why it builds trust faster than a testimonial.
From your process page: three posts
9. What happens after someone gets in touch.
First line: "Here is exactly what happens in the first two weeks."
Body: the stages, one per line, in order.
Last line: the first step and where it lives.
10. The step clients want to skip.
First line: the step, and that everyone wants to skip it.
Body: what happens when it is skipped, what it protects, why you hold the line.
Last line: the one question that tells you whether a client will respect it.
11. What I need from you, and when.
First line: "The engagement goes faster when you know this on day one."
Body: the client's obligations, one per line.
Last line: what you do to make each one easy.
It reads as respect for the reader's time, because it is.
From your reviews and results: three posts
12. The result, and the decision that produced it.
First line: the outcome, in the client's words, with permission.
Body: the situation, the choice made, why that choice and not the obvious one.
Last line: the service page for that work.
The reasoning is the post; the number is the hook.
13. What clients say afterward that they did not expect.
First line: the surprise, quoted.
Body: why it happens, and what it says about how you work.
Last line: what to expect if they hire you.
14. The engagement that did not work, and what I changed.
First line: an honest miss, without the client's identity.
Body: what went wrong, what you changed in the process, what it prevents now.
Last line: the process page.
On LinkedIn this earns more trust than any win, and almost nobody posts it.
From your about page: four posts
15. The standard I hold that clients notice.
First line: the standard, as a sentence.
Body: three examples of it in the work.
Last line: what it costs you, and why you pay it.
16. The thing I believe that peers argue with.
First line: the belief.
Body: why you hold it, the strongest objection, why you still hold it.
Last line: the question back to the room.
The one post on this list that peers share, which is how buyers find you.
17. Why I do it this way.
First line: the choice that looks odd from outside.
Body: the reasoning, and the alternative you rejected.
Last line: who it is right for.
18. The mistake I see most in my field.
First line: the mistake, named without a person attached.
Body: why smart people make it, what it costs, the fix.
Last line: how to check whether you are making it.
Two formats that carry more than one idea
19. The document carousel.
Any idea above with more than three parts is a carousel: a PDF uploaded to the post, one point per page.
The LinkedIn reader will swipe for a full thought where an Instagram reader would not.
Carousel post ideas for a service business has 18 of them with the slide arc, and the LinkedIn carousel size guide covers the document format.
20. The plain text post with a real first line.
No image, no link in the body, one point, well earned.
It is still the format that travels furthest on LinkedIn for a professional, because it reads like judgment rather than marketing.
A note for regulated advisors
Financial advisors, accountants and anyone under a compliance regime already know that a LinkedIn post is a public statement.
The website method helps here rather than hurts: the service page, the FAQ and the process page have usually been through review already, so a post built from them starts inside the lines.
Results and client stories still need permission and the compliance check every time.
How to make one without the blank page
Every idea on this page starts from a page you already have.
That is also how Boomp works.
It is done-for-you social media software: give it your website, and it writes the posts in your voice, makes the images and carousels, and publishes to LinkedIn and eight other channels after you approve each one.
The free step shows you the difference on your own site.
The free post generator makes one complete post from your website before any email, and the free carousel generator does the same with a multi-page carousel.
If what comes back is true and sounds like you, the making was the work you wanted removed.
