How to run a ghostwriting agency for LinkedIn and X

This guide is for ghostwriters who have a few clients and want to build a team, and for content agencies adding LinkedIn and X ghostwriting. Full disclosure: we make Eden, which has an Agency plan for teams writing for many clients. The system below works with any tools.

What makes ghostwriting different

Ghostwriting is not social media management. The client's name is on every post, so the bar is higher:

• Voice is the product. If a post doesn't sound like them, it fails, even if it is well written.
• Ideas come from the client. Their stories, opinions, and wins are the raw material. You can't research your way around that.
• Trust is everything. You are speaking for someone in public. Approvals and privacy matter more.

Build the agency around those three facts.

Step 1: Pick the client and the offer

The most common ghostwriting clients are founders, executives, consultants, and coaches who want to build an audience on LinkedIn or X but have no time to write. Pick one group, and make the offer concrete:

• "12 LinkedIn posts a month, written from two 30-minute calls."
• "Daily X posts and one thread a week, in your voice."
• "LinkedIn plus a weekly newsletter, from one monthly interview."

Price it as a monthly retainer with a three-month minimum. We walk through the math in how to price content agency services.

Step 2: Capture the voice before you write

Every client gets a voice document on day one. Build it from three sources:

1. What they've already written. Old posts, emails, talks, podcast transcripts. Pull out the phrases they repeat.
2. A kickoff interview. Ask how they got where they are, what they believe that others in their field don't, and the stories they tell over and over.
3. What they hate. Words they would never use, topics that are off limits, people they don't want to sound like.

Then write it down on one page: how they open a post, how long their sentences run, the stories they tell, the beliefs that show up again and again, and 5 to 10 example posts that sound exactly right.

This document trains every writer you hire. It is also what makes AI drafts usable. A Custom AI that reads the voice doc and the best examples drafts far closer to the client than a blank chat. See AI that writes in your voice.

Step 3: Run a weekly content loop

The same loop for every client, every week:

Step	What happens
Interview	A short call or voice memo from the client. One story, one opinion.
Research	Find what is working on LinkedIn and X in their niche this week.
Draft	Turn the interview into posts, using proven formats from research.
Approve	The client reviews by a set deadline.
Schedule	Posts go into the queue for the right account at the right times.
Review	Check what worked, and feed it into next week.

The interview is the step agencies skip and regret. Without fresh stories from the client, posts drift into generic advice that could be anyone's.

Step 4: Research what works on LinkedIn and X

Good ghostwriters don't guess at formats. They study outliers: posts that did far better than that creator's normal. An outlier from a small account tells you more than a routine hit from a famous one, because the idea did the work, not the audience size.

For each client, save the best outliers from their niche each week, and note why each one worked: the hook, the structure, the angle. Over time this becomes a swipe file of proven formats to pour the client's own ideas into. More on the method in how to find what content works in your niche, and tools in the best content research tools.

Eden's Discover scores outliers across X, LinkedIn, and four other platforms, so you can filter a niche by how far each post beat its creator's baseline. A clear warning: research gives you formats, not content. Never copy another creator's post. Use the shape, fill it with your client's story.

Step 5: Make approvals easy

Founders are busy. Make approval take five minutes:

• One approver. Usually the client, sometimes their chief of staff.
• A fixed day. Drafts arrive Monday, feedback by Wednesday.
• A clear default. No reply by the deadline means posts go out as written. Agree on this at kickoff.
• Feedback in one place, not split across email, Slack, and texts.

Track their edits. If a client keeps changing the same kind of thing, update the voice doc so the next draft gets it right.

Step 6: Schedule natively for each platform

LinkedIn and X reward different things, so don't paste the same post into both. A LinkedIn post can run longer with line breaks. An X post needs to land in 280 characters or become a thread. We cover how to adapt one idea for both in how to cross-post between X and LinkedIn.

Use a scheduler that keeps each client's accounts separate and handles the formats you sell: X threads, LinkedIn PDF carousels, and first comments. Eden schedules X threads with quote posts and auto-retweet, LinkedIn posts and PDF carousels, and first comments where the platform allows. See how to schedule LinkedIn posts and how to schedule Twitter threads.

Step 7: Hire writers without losing the voice

You will hit a ceiling around the number of voices one person can hold in their head. To grow past it:

• Hire for editing taste first. A good editor can tell when a draft doesn't sound like the client.
• Assign clients, not posts. One writer owns a client's voice. Switching writers every week shows.
• Train from the voice docs. New writers read every doc and every approved post before drafting.
• Review the first month closely. The founder or lead editor checks every draft until the writer is consistent.
• Share your process as tools. On Eden Agency, you build a Custom AI or skill once (your hook writer, your research steps, your editing checklist) and share it into every client workspace. Every writer starts from the same method, and when you improve it, every client gets the change.

Step 8: Keep everything private

Clients share things they don't want public: deals, numbers, opinions about competitors. Protect that:

• One private space per client. Their voice doc, interviews, and drafts never sit next to another client's.
• Limited client access. Clients see their drafts and what you share, not your internal notes or your AI chats.
• Clear rules on credit. Ask before you name a client as a case study. Many ghostwriting clients prefer you don't.

On Eden Agency, each client gets a private workspace, and you can invite the client free as a guest on only the boards you pick. Guests never see your AI chats.

Frequently asked questions

How do I start a ghostwriting agency?

Pick one client type, usually founders or executives, and one offer on LinkedIn or X. Build proof by writing for yourself and one or two discounted clients. Then document your voice capture and weekly loop so you can hire. Our guide to starting a content agency covers the full setup.

Can AI do the ghostwriting?

AI can draft fast, but the ideas and stories still have to come from the client, and an editor still has to check the voice. Agencies that do well with AI give it the client's voice doc and examples, and keep a human on every final draft.

How many clients can a ghostwriter handle?

It depends on how many posts each client gets and how much of the process is documented. Track your hours per client for a month, then decide. When you hit the limit, hire a writer and give them your voice docs.

Is it ethical to ghostwrite social posts?

Ghostwriting is common for executives and public figures. Posts should reflect the client's real views and experiences, which is why interviews and approvals matter. Never make up stories or results for a client.
