Using LinkedIn with Publlish

Learn how to connect your LinkedIn Page or Profile to Publlish, schedule LinkedIn posts, publish carousels and videos, and manage LinkedIn content with your team.

LinkedIn is where B2B marketing teams, agencies, and professional brands build authority and generate pipeline. It rewards consistency — and consistent posting on LinkedIn is much easier when you're planning and scheduling in Publlish rather than drafting on the fly.

This guide covers how to connect LinkedIn to Publlish, what content formats are supported, and how to get the most out of LinkedIn as part of your multi-channel publishing workflow.

Post text updates, images, videos, and documents

Collaborate with your team on LinkedIn content before it goes live

LinkedIn Pages vs. LinkedIn Profiles

Publlish supports both LinkedIn Pages (company pages) and LinkedIn personal Profiles, but they behave differently.

LinkedIn Pages are company or brand pages. They have full API access for scheduling and analytics. If you're a marketing team publishing on behalf of a business, you'll connect the company Page.

LinkedIn personal Profiles can also be connected, which is useful for founders, executives, or personal brand building. Some analytics features may be more limited for personal profiles compared to Pages.

If you're an agency managing LinkedIn for multiple clients, connect each client's LinkedIn Page separately — each counts as one channel on your plan.

Requirements Before You Connect

For LinkedIn Pages: You must be a Super Admin or Content Admin of the Page
For LinkedIn Profiles: You must be logged into the LinkedIn account you want to connect
LinkedIn requires re-authorisation periodically — plan to refresh the connection every few months

LinkedIn post writing tips:

LinkedIn posts perform best when they start with a strong hook in the first 1–2 lines — this is what shows before the "see more" cutoff
The sweet spot for LinkedIn post length is 1,300–2,000 characters — enough to tell a story, not so long it loses readers
Line breaks matter on LinkedIn — use short paragraphs and white space to make posts scannable
LinkedIn's algorithm favours posts that generate comments over likes. Write posts that invite a response — ask a question, share a contrarian view, or invite people to share their experience
Hashtags on LinkedIn work best in small numbers — 3–5 relevant hashtags is the recommended range

LinkedIn Content Formats Supported in Publlish

Text Posts

Fully supported. LinkedIn text-only posts can perform extremely well when the writing is strong — especially for thought leadership content from founders or executives.

Character limit: up to 3,000 characters for personal profiles, up to 700 characters for Company Pages (check current limits as LinkedIn updates these).

Image Posts

Fully supported. Single images and multi-image posts (up to 20 images in one post) are supported.

Image specs:

Formats: JPG, PNG, GIF (static)
Maximum file size: 5MB per image
Recommended resolution: 1200 x 627px for landscape, 1080 x 1080px for square

Video Posts

Fully supported for scheduling and auto-publishing.

Video specs:

Format: MP4 recommended
Duration: 3 seconds to 10 minutes
File size: up to 5GB
Resolution: 256 x 144 minimum, 4096 x 2304 maximum
Aspect ratios: 1:2.4 to 2.4:1

LinkedIn video gets strong reach — especially native video uploaded directly rather than shared YouTube links. Always upload video directly to get better distribution.

Document Posts (PDF Carousels)

LinkedIn document posts — where you upload a PDF and it displays as a swipeable carousel — are one of the highest-performing formats on the platform.

Publlish supports scheduling document posts. To use this format:

Create your slides or carousel as a PDF
Upload the PDF in the Publlish composer as a document attachment
Write your caption
Schedule as normal

PDF specs:

Maximum 300 pages
Maximum 100MB file size
File format: PDF only

Document carousels work well for step-by-step guides, frameworks, data insights, and how-to content. They tend to generate strong saves and shares.

LinkedIn Articles and Newsletters

LinkedIn Articles and Newsletters (long-form content published natively on LinkedIn) are not currently supported through Publlish. These must be created and published directly on LinkedIn.

LinkedIn Analytics in Publlish

Publlish pulls LinkedIn performance data into your analytics dashboard. Available metrics for LinkedIn Pages include:

Impressions
Clicks
Engagement rate
Reactions, comments, and shares
Follower growth
Visitor demographics (page views, unique visitors)

For deeper LinkedIn analytics — such as talent brand metrics or LinkedIn Campaign Manager data — use LinkedIn's native analytics tools.

Cross-Posting LinkedIn with X

LinkedIn and X are the two most natural platforms to cross-post professional content. A thought leadership post, industry insight, or product announcement works well on both — though the tone and length need to be adjusted.

In Publlish, select both LinkedIn and X when composing a post. Write the full version for LinkedIn (1,300+ characters) and a concise 280-character version for X. Both go out at the same time with one scheduling action.

Troubleshooting LinkedIn in Publlish

My LinkedIn post failed to publish LinkedIn connections expire and require periodic re-authorisation. Go to Channels and refresh your LinkedIn connection. See how to refresh a channel →

I can't connect my LinkedIn Page You must be a Super Admin or Content Admin of the Page. Check your role in LinkedIn's Page Admin settings. If you're listed as an Analyst or Curator, you won't have publishing access.

My video isn't uploading Check the file format (MP4 is recommended) and file size (under 5GB). Very large files may time out — try compressing the video before uploading. Video upload troubleshooting →

My analytics don't match LinkedIn's native data Small discrepancies between Publlish analytics and LinkedIn's native analytics are normal and usually due to timing differences in data syncing. See why analytics may differ →

LinkedIn Best Practices for Marketing Teams

Post 3–5 times per week. LinkedIn's algorithm rewards consistency. Posting daily or near-daily keeps your Page visible in followers' feeds without being penalised for over-posting.

Lead with a hook. The first 1–2 lines of your post are what show before the "see more" button. Make them compelling enough to earn the click.

Use document carousels for high-value content. PDF carousels are consistently one of LinkedIn's highest-performing formats — especially for educational, framework-style, or data-driven content.

Engage with comments quickly. LinkedIn's algorithm boosts posts that receive comments in the first 60–90 minutes. Being responsive early drives more reach.

Personalise executive content separately from company page content. Founder and executive posts typically outperform company page posts on LinkedIn because they feel more human. Consider running both a company page and personal profiles for key team members.
