LinkedIn

LinkedIn is a brand name with a specific shape: LinkedIn. Small errors-Linkedin, Linkdin, Linked-In, Linked In-look careless on resumes, emails, and profiles. Below are fast rules, ready-to-copy examples, and quick fixes you can apply immediately.

Quick answer

Write LinkedIn - capital L and capital I in the middle, no space, no hyphen. Use clear verb phrases (for example, "message on LinkedIn" or "connect on LinkedIn") instead of making the brand into a verb.

• Wrong: Linkedin, Linkdin, Linked-In, Linked In, linkedin
• Right: LinkedIn
• Verb tip: Replace "I'll Linkedin you" with "I'll message you on LinkedIn."

Core explanation: why the shape matters

The brand joins "Linked" and "In" with internal capitalization: LinkedIn. That internal capital I is part of the official styling and signals attention to detail in professional writing.

• Official form: LinkedIn
• Common incorrect forms: Linkedin · Linkdin · Linked-In · Linked In · linkedin

Capitalization and spelling (grammar)

The middle letters are capital I then lowercase n. Common mistakes swap the letters or lowercase the I. If you mistype it often, add a text shortcut or autocorrect entry for LinkedIn.

• Pattern to remember: capital L, then letters, internal capital I, final lowercase n → LinkedIn
• Quick fix: copy "LinkedIn" from a trustworthy source if unsure

Hyphenation: don't add a hyphen

The brand is a single word. Inserting a hyphen turns the name into a visible typo and breaks the official form.

• Wrong: Linked-In
• Right: LinkedIn
• Punctuation: place commas and periods outside the name - "I saw your post on LinkedIn."

Spacing: don't split the word

Keep LinkedIn as one word. When you share a profile URL, the link itself is usually lowercase (linkedin.com/in/yourname), but in text keep the brand capitalized.

• Wrong: Linked In
• Right in prose: LinkedIn
• Right for a URL: linkedin.com/in/yourname (URLs are typically lowercase)

Real usage and tone: formal vs. casual

In formal writing (resumes, cover letters, bios) always use the exact brand form: LinkedIn. In casual messages, keep capitalization but use natural phrasing and avoid verbing the name.

• Formal: "Connect with me on LinkedIn."
• Casual: "Saw your post on LinkedIn - great point!"
• Avoid: "I LinkedIn'd him" or "I'll Linkedin you." Use "I messaged him on LinkedIn" or "I'll message you on LinkedIn."

Try your own sentence

Test the whole sentence rather than the isolated phrase. Context usually clarifies the correct verb and phrasing.

Memory tricks and quick checks

Small habits cut errors: visualize Linked + In, add a keyboard shortcut, or hover a link to confirm the domain before typing the name.

• Tip: Save "LinkedIn" as a keyboard shortcut to replace frequent typos
• Quick check: If the link is linkedin.com, write the brand as LinkedIn

Similar mistakes with other brand names

Many brands use internal capitalization. Match each brand's official styling: YouTube, iPhone, eBay, and so on. When unsure, copy the name from the brand's site.

• Wrong/right: Youtube → YouTube; Iphone → iPhone; Ebay → eBay
• Treat brand names like proper nouns-use the form the brand uses.
