- Bio body = the 160-character description below your name. URLs auto-link if they have
https://prefix. - Website field = a dedicated 100-character URL slot, displayed under bio with a link icon.
- Both are clickable. Website field gets visual prominence; bio body URLs are inline.
- Best practice: use Website field for primary URL + add 1-2 supporting URLs in bio body.

Why X Made Two Slots
Historically (Twitter days), the Website field was the only way to add a URL ??” bio body was strictly text. Around 2014-2015, bio body URLs gained auto-linking. Now both slots co-exist:
- Website field = legacy "primary URL" slot.
- Bio body URLs = flexible inline placement.
Tracking Differences
Both slots route through t.co. X tracks aggregate clicks via t.co. To distinguish bio body vs Website field clicks:
