### Explanation Link-aggregator services (Linktree, Beacons, Carrd, Bento, Linkin.bio, Stan.store, Koji, Lnk.bio) and personal-page builders (about.me, Notion-published pages, GitHub Pages personal sites, custom domains) exist because a single bio slot on Instagram or TikTok isn't enough. People use them to collect every link they consider "publicly mine" — a personal blog, a portfolio, a Patreon, a Discord invite, an email signup, sometimes a personal phone or business address. A parallel B2B variant of the same idea is the virtual business card: HiHello, Blinq, Popl, Mobilo, Linq, and similar services replace the paper card with an NFC tap or QR code that opens a hosted profile page containing the holder's name, role, employer, direct phone, work email, office address, LinkedIn URL, and assorted other channels. Because the whole point of these cards is shareability, the pages are almost always public and indexable. For OSINT, both variants are a single-point-of-pivot. Once you find someone's link-aggregator URL, personal site, or virtual business card, you typically have a complete map of every adjacent identity they consider their own. Usernames across the listed platforms often differ from each other, but the aggregator ties them together explicitly — collapsing what would otherwise be several independent identity-resolution searches into one. The two variants also complement each other: a personal Linktree may show a Twitch handle and a Patreon while the same person's HiHello card exposes their work email, mobile number, and exact job title at a named employer. ### Examples {{some links to articles, videos, etc}} ### Types business, behavioural ### See also - {{internal links to similar functionalities}} ### Typical weaknesses - [[SOWEL-8.
