Bold, italic and 23 other copy-paste styles for LinkedIn posts, headlines and your About section — with the accessibility trade-off spelled out.
These styles are Unicode characters that look like fonts, not real formatting. Screen readers announce them one character at a time by their full Unicode name, so a fully styled post is unreadable to anyone using one — and search engines and in-app search cannot match them as words. Use them for a name, a heading or one emphasised phrase, and keep the text you want found or read aloud in plain characters.
LinkedIn's post composer offers no bold or italic button, which is why Unicode styling has become standard practice for breaking up long posts. You're not formatting text; you're substituting characters that look bold. That's the whole trick.
Screen readers announce 𝐁𝐨𝐥𝐝 as “mathematical bold capital B, mathematical bold small o…”, one character at a time. On a platform with a large accessibility-conscious professional audience, a fully styled post is genuinely unreadable to some of your readers. Use it for a heading or a single emphasised phrase, not body text.
LinkedIn matches plain text when people search for skills, titles and keywords. A headline reading 𝒮𝒪𝒮 𝒬𝓸𝓷𝓼𝓾𝓵𝓽𝒪𝓷𝓽 will not appear for “SaaS consultant”. Your headline is the last place to experiment — it's the field recruiters search.
Video posts outperform text on LinkedIn, and most people avoid them because reading to camera is hard. Teleprompter.com scrolls your script while you record so you keep eye contact. Free on iOS, Android, Mac and the web.
Type your text above, tap the Bold style to copy it, and paste it into your post, headline or About section. LinkedIn has no bold button, so this substitutes Unicode mathematical bold characters that look like bold text in every client.
Yes, and it's worth taking seriously. Screen readers read each mathematical character by its full Unicode name rather than as a letter, so a styled paragraph becomes a stream of nonsense to anyone using one. Restrict styling to a short heading or one emphasised phrase and keep your body copy plain.
It affects search directly: LinkedIn indexes plain text, so styled keywords won't match. There's no evidence LinkedIn's feed algorithm penalises styled posts, but styled text can reduce dwell time if people find it harder to read, and that does matter.
You can paste styled characters into your headline, but it's the single worst field to do it in. Your headline is what recruiters and search match against, and styled characters break that match. Style your post copy instead.
Bold, sans bold and italic read as deliberate emphasis. Script, fraktur, bubble and upside-down styles read as decorative and tend to undercut a professional tone — they're available above, but they're not what LinkedIn readers expect.
