What LinkedIn doesn't publish
Where "see more" cuts a post. It depends on the screen and on your line breaks, and LinkedIn gives no figure. The only way to know is to look: paste your post into the Post Preview.
How much of a headline shows in search results and under your comments. No figure either, so put what matters first.
A newsletter's name, and an article's title. LinkedIn's help pages give no limit for either. Only the SEO title has one: search results cut it after 60 characters.
Using the 3,000
A post can hold 3,000 characters. What shows before "see more" is what everyone sees, so put the point there, and use the rest for what backs it up. Our guides on hooks and formatting go further, and the Post Formatter makes a long post easier to scan.
