LinkedIn
Character Counter
Check every LinkedIn field in real time — posts, headlines, about section, connection requests and InMail. Free, no signup, your text stays in your browser.
💡 Engagement sweet spot: 800–1,500 chars. Only the first 210 chars show before "see more" — make them count. Posts over 1,500 chars can perform well if every line earns the next.
💡 Headline tip: Only the first ~70 chars show in LinkedIn search results on mobile. Lead with your most important keyword — job title or value proposition — before the first pipe (|) or dash.
💡 About section tip: The first 300 chars are your elevator pitch. Start with what you do and who you help — not "I am a passionate professional with 10+ years..." which wastes your fold.
💡 Connection tip: 300 chars is tight. Best-performing notes: mention one specific thing about their work, state why you want to connect, no pitch. Under 200 chars performs better than using the full 300.
💡 InMail tip: Response rates drop sharply above 400 characters. The subject line is the most-read element — make it specific to the recipient, not a generic "Opportunity for you".
