A link tree (also called a "link in bio" tool) is a service that displays multiple URLs on a single landing page. Since platforms like Instagram and TikTok limit how many links you can place in the profile section, a link tree serves as a hub page that directs visitors to all important destinations from a single link.
A typical link tree layout consists of a profile image, a short bio, and vertically stacked link buttons. Each button is labeled with destinations like "Latest Blog Post," "YouTube Channel," "Online Shop," or "Contact," and tapping one navigates to the corresponding page.
URL shortening services and link trees complement each other. Shortening the link tree page URL itself makes the profile link cleaner. Additionally, using shortened URLs for each link within the tree enables individual click tracking to see which links get the most engagement.
An SEO consideration: since link tree pages are hosted on the service's domain (e.g., linktr.ee), they do not directly contribute to your own domain's SEO authority. If SEO matters, creating a link aggregation page on your own domain and directing traffic via a shortened URL is more effective.
Popular services include Linktree, Lit.Link, Bento, and Later's Link in Bio. Free plans cover the basics of grouping links, while capabilities such as detailed analytics typically sit on higher paid tiers. Plan boundaries and prices change often, so check each service's current pricing page when you compare them.
