Maximising the 256-Character Bio

• Lead with what you do (5-10 words).
• Concrete proof (5-10 words).
• Bio link URL.
• Optional: 1-2 hashtags or emoji.

Examples

"Designer + dev. Helping SaaS founders build products that convert. Free toolkit ?†’ unil.ink/alex" (94 chars)

"Newsletter writer. Real-world growth tactics, no hype. 3,847 subscribers. Sign up: alexnews.com" (97 chars)

Custom Domain Handle

Unique to Bluesky: handle can be your domain. Example: @yourname.com instead of @yourname.bsky.social.

Length depends on your domain. Some long custom domains (e.g., @yourbrand.com) display fine on Bluesky.

URL Counting in Posts

Bluesky counts URL full length in 300-char post limit (unlike X which counts URLs as 23 chars). Long URLs eat into your post real estate.

Strategy: shorten URLs first (Bitly, unil.ink) before posting.

Display Name Strategy

64 chars is more flexible than X's 50:

• "Alex Designer (alex.com)" (24 chars)
• "Alex Designer ???? + dev sharing growth tips" (43 chars)
