Link in bio
Trend that emerged from Instagram's limit to one bio link. Drives the entire aggregator market (Linktree, Beacons). Standard phrase in Instagram captions: "Link in bio for details" instead of link in the post.
Instagram historical reason: push people to profile views (ad revenue). TikTok followed Instagram pattern. Modern offering: Bluesky + Mastodon allow links directly in posts → reduces "link in bio" contrast. Brand strategy: shopping page with 5-10 products linked. Substack + Patreon + Discord server usually all in bio aggregator. Anti-pattern: 30+ links in Linktree → user overwhelm, no one clicks.
