Platform Size (Monthly Active Users, 2025)

Note: LinkedIn figure is registered members, not monthly active users. MAU estimates for LinkedIn are not publicly disclosed.

Link Constraints by Platform

• Instagram and TikTok each allow only one clickable link in the profile bio. Video captions on both platforms do not support clickable hyperlinks. This constraint created the "Link in Bio" product category — a single URL that aggregates multiple destinations.
• Twitter (X) automatically wraps all posted URLs in its own t.co short domain. Twitter used TinyURL as its default shortener from launch until May 2009, then Bitly until introducing t.co. The 140-character limit introduced at Twitter's launch in July 2006 is widely credited as the event that made URL shorteners mainstream.
