LinkedIn offers no formatting in posts. Yet readability is exactly what drives reach on LinkedIn: only the first ~210 characters show in the feed before the "see more" link appears.
A bold subheading structures longer posts and makes them skimmable. You can bring the same structure to your headline and about section.
In a professional setting though: use it sparingly. A post entirely in bold quickly reads as unserious — and screen readers struggle with these characters, which matters especially on a business platform.
Frequently asked questions
Can you format LinkedIn posts in bold?
Not through LinkedIn itself. Using Unicode characters from this tool works anyway — copy and paste.
Does it work in the about section?
Yes — in posts, comments, your headline and the about section.
Does it look professional?
In moderation, yes — for subheadings, say. Whole paragraphs in special characters quickly read as pushy.
Does it affect accessibility?
Yes. Screen readers often read these characters unintelligibly. Use them only for individual highlights.
