Search entity
Also called: entity, named entity, entity SEO
Search systems stopped treating queries as strings of characters a long time ago and started mapping them to things: a named person, a place, a product, an organisation, a concept. Each of those is an entity, stored with its attributes and its connections to other entities, which is why searching a well-known creator's name can return a panel of facts instead of ten links.
For a channel this makes consistency worth the effort. The same name, the same handle and the same description of what you do across your site, your profiles and your socials helps engines join the references into one recognised thing. Scattered variations get treated as scattered mentions, and nothing accumulates.
