A custom alias is the memorable, editable part of the short link that comes after the slash (e.g., links.mybrand.co.za/**spring-sale**). Instead of a random string of characters like _aB1c2D_, customizing the alias makes your links readable, trustworthy, and on-brand. A link like linktransform.com/your-custom-link-name is far more clickable than one with a random ending.
