# Brand profile

> The brand profile — name, aliases, website, and tracked domains — that drives mention detection and Owned-vs-Earned citation classification in 3RD.

Your brand profile holds your **name**, **known aliases**, **website**, and **tracked domains and subdomains**. It's a small settings page with an outsized impact: it defines what 3RD looks for in every AI answer.

## Why aliases matter

Aliases are how 3RD detects [mentions](/metrics/visibility). The mention detector already handles spelling variations, capitalization, possessives ("Acme's"), and suffixes ("Acme Inc") — but it can't guess names it doesn't know. If customers call you "ACME Corp", "Acme Analytics", or an old product name, add each as an alias.

**Missing aliases undercount you** — answers that clearly recommend you register as non-mentions, deflating visibility, sentiment, and rank all at once.

## Why domains matter

Your registered domain (and subdomains like `blog.acme.com`) is how 3RD classifies every citation as **Owned** or **Earned**. If your content lives on more than one domain — a docs site, a country site, a product subdomain — make sure they're all tracked, or your [Citation Share](/metrics/citation-share) will read lower than reality.

<Warning>
  If your visibility or citation share looks implausibly low, check this page first. An incomplete alias list or a missing domain is the most common cause of "the numbers look wrong."
</Warning>
