Here are the key difference between a post and an article on LinkedIn: 1. Articles can include headers and images, while posts cannot. 2. Articles can be much longer in terms of content: 3,000 character limit on status updates vs. 110,000 on articles. 3. Articles tend to be more formal and are presented as blog posts and more polished than casual posts. 4. Articles are indexed by Google and can be found in search engine results, where status updates do not appear to be do. 5. You can write a newsletter wth an Article but not with a Status Update.
