How do you automate Bluesky posts?

How is Bluesky different from Twitter for content?

Bluesky rewards conversational, genuine writing over broadcast-style content. The platform's core user base is people who left Twitter because they were tired of algorithmic optimization and performance.

For a detailed breakdown of how to adapt content between both platforms, read our Twitter and Bluesky cross-posting guide.

Do links count as characters on Bluesky?

Yes, links count toward your 300 character limit on Bluesky. Unlike Twitter, Bluesky does not automatically shorten URLs to a fixed character count — the full URL length counts against your limit. Use a URL shortener if you need to include a long link and stay within 300 characters.
