What should I post on LinkedIn?
Formats LinkedIn supports
LinkedIn's help centre lists the files you can post: images such as JPEG, PNG, GIF and WEBP; documents such as PDF, DOC/DOCX and PPT/PPTX; and video such as MP4 and MOV. It notes a 100 MB file size limit and a 300-page limit for documents (checked 7 October 2026). A short PDF carousel of five to ten slides is an easy way to share a step-by-step lesson.
A weekly rhythm that builds trust
LinkedIn says that if you regularly post content that is engaging and professionally relevant, it may recommend you to other members as someone to follow, and that followers see the posts you share publicly. So consistency on one professional topic matters more than volume.
- One lesson post: something you learned at work and how others can use it.
- One proof post: a project, result or case study with real details you are allowed to share.
- Comment thoughtfully on three posts by people in your field every week.

Frequently asked questions
What should I post on LinkedIn?
A lesson from real work, a useful breakdown, or a question you can answer. A recycled quote is easy to skip.
How often should I post?
Once or twice a week is enough if the posts are specific. Daily posting is optional.
Do hashtags matter?
A few relevant ones can help. The first two lines matter more, because that is what people see before they expand the post.
Can I write with AI?
You can draft with it. The example and the opinion should be yours. LinkedIn has asked that AI-assisted posts still reflect the member.
Should I post documents or video?
Use the format that fits the idea. A checklist can be a document. A demo can be a short video.
What should I avoid?
Fake stories, invented metrics, and comments that are only there to be seen.
