What goes in a Mastodon bio
Your Mastodon bio is the short "about" block under your display name, capped at 500 characters on most instances (admins can raise or lower it). Below it sit four separate metadata fields, each with a label and value, where people put links, pronouns and locations. The thing most newcomers miss: there's no algorithm here, so nobody surfaces you. Your bio plus hashtags are how people decide to follow you, which makes plain-language topics and a verifiable link far more useful than a clever one-liner.
Mastodon bio tips
- List the actual topics you post about as hashtags; Mastodon's discovery leans on tags, not an algorithm, so be literal.
- Put your website in a metadata field, not the bio, and add rel="me" on that page to earn the green verified checkmark.
- Use the four metadata fields for pronouns, location and links so the 500-character bio stays focused on who you are.
- Skip front-loading emoji and symbols; screen readers announce each one, which buries your actual description for blind followers.

Latest questions readers ask us about this topic.
What's the character limit for a Mastodon bio?
500 characters by default, but each Mastodon instance runs its own software, so an admin can set it higher or lower. The four profile metadata fields are counted separately and typically allow around 255 characters per value.
How do I get the green checkmark on my Mastodon bio?
Add a link to your own site in a metadata field, then place a link back to your Mastodon profile with rel="me" on that site. Mastodon checks it and marks the field verified in green, confirming you control the page.
Do hashtags in a Mastodon bio do anything?
Yes. Mastodon has no recommendation algorithm, so discovery runs on hashtags. Tags in your bio make your profile appear when people browse or follow those topics, which is one of the main ways new followers find you.
