How to Use the LinkedIn Auto Poster

Before you start

• Create a Google Sheet or CSV file with your posts:
  • One post per row.
  • Place all posts in column A (or specify a different column by name).
• Awareness of safe posting habits:
  • While LinkedIn doesn’t enforce strict posting limits, spreading posts throughout the workday is more natural and reduces the chance of being flagged as automated.

Step 1: Connect your LinkedIn account

To let the Phantom act on your behalf:

1. Install the PhantomBuster browser extension and connect your LinkedIn session in one click.
2. If you’re not using Chrome or Firefox, you can retrieve your session cookie manually (see our cookie guide).

Check your browser user agent
Make sure your browser is up to date before connecting your account. 
→ If your Chrome or Firefox version is outdated, your session cookie may expire much more quickly, and you’ll need to reconnect often.

Step 2: Provide your post content

Paste the spreadsheet URL into the Phantom’s setup.

• The file must be one of the following:
  • A Google Sheet URL (make sure it’s shared with “Anyone with the link”).

  • A CSV file URL (make sure it’s publicly accessible, and note that CSV upload is only available on paid plans).

    → By default, the Phantom will use column A of your sheet. If your posts are in another column, specify the column header name (not “A” or “B,” but the text in row 1).

Step 3: Choose how many posts to publish per launch

• Enter the number of posts to send per launch.
• Leave the field blank to process all posts in your input at once.
• For a more natural cadence, post only 1–2 items per launch and schedule multiple launches across the week.

Step 4: Select launch frequency

Choose how often the Phantom should run:

1. Launch manually: Start the Phantom yourself whenever you need.
2. Launch once at a specific time: schedule a one-time run at a set date and time.
3. Launch repeatedly: schedule regular runs (e.g. once per day, several times during working hours).
4. Launch after another Phantom: chain automations together so this Phantom starts right after another finishes.
5. Advanced scheduling: customize the exact minutes, hours, days, or months when the Phantom should run.

→ For a complete walkthrough of scheduling options, see our guide to scheduling Phantoms automatically.

Step 5 (Optional): Advanced settings

Advanced settings are available if you want to fine-tune how your Phantom runs, but by default they’re already optimized for most use cases.

We recommend leaving them as they are unless a guide specifically instructs you to change something.

→ For a detailed overview of all advanced options (like execution limits, retries, email notifications, proxies, webhooks, and file management), see our Advanced settings guide.

Launch and results

When you’re ready:

1. Click Launch to start your Phantom.
2. Once it finishes, check the Results tab to confirm which posts were published.
3. Download your results as a CSV or JSON file.

→ To learn how to export your data to Google Sheets, integrate with other tools, or reuse it in more automations, check our Access and Export your Phantom Results guide.

Export and input limits on the Free plan
If you’re on the Free plan or Free trial, some features are limited:
- CSV exports include only the first 10 rows of results.
- CSV download links (for dynamic viewing in Google Sheets or integrations) are not available.
- JSON exports are not available.
- CSV upload as an input method is not supported.
To unlock all features, you’ll need to upgrade to a paid plan.

Tips and troubleshooting

Common pitfalls

• Using a private Google Sheet → make sure it’s shared with “Anyone with the link.”
• Using column letters instead of header names when specifying input.
• Scheduling too many posts in a short timeframe (unnatural posting pattern).
• This Phantom only supports posts. It cannot repost existing content.
• Works only from your personal profile, not company pages.
• Supports text and links only. Images and videos are not supported.

If you run into issues

• Check how to troubleshoot your phantom using Logs.
• Browse the Fix Issues & Troubleshoot Errors section for solutions to common problems.
• Review our Automation Rate Limits by Platform guide.
• Check our Best Practices for Social Media Automation guide.

Suggested automations

After publishing posts, you can:

• Analyze your post & extract leads → use the LinkedIn Post Commenter and Liker Scraper to capture who engaged with your content.
• Enrich your leads → run the LinkedIn Profile Scraper on those profiles to collect full details.
• Connect with engaged leads → use the LinkedIn Post Engagers to Lead Outreach workflow to automatically send invites and follow-ups to people who interacted with your post.
