Mentions, citations & sources
These three words get used interchangeably, but they measure different things. Getting the distinction right is the difference between "the AI talked about us" and "the AI trusted our website."
Mention
A mention is when your brand name appears in the text of an answer. The engine wrote your name. Mentions drive your visibility metrics and Share of Voice; they're about being part of the conversation a customer reads.
A mention doesn't require the engine to link to you. It can name your brand from its own training or from a completely different website's content.
Citation
A citationis when the engine attributes part of its answer to a specific page and links to it. Engines like Perplexity and ChatGPT's search mode show numbered references; a citation is one of those references pointing at a URL.
A citation of yourdomain is a strong signal: the engine didn't just know your name, it read your page and treated it as a source worth crediting. You can be mentioned without being cited, and, less commonly, cited without your brand name appearing in the visible text.
Source
A sourceis any page an engine drew on to build an answer, whether or not it's your domain. AppearIn AI tracks the full set of sources behind the answers in your category so you can see which websites the engines actually trust when they talk about your space, competitor blogs, review sites, directories, forums, and documentation.
Where the leverage is
The source list is one of the most actionable views in the product. If a third-party review site is cited again and again across your prompts, getting listed or improving your entry there can do more for your visibility than another page on your own site.Side by side
| Signal | Means | Answers the question |
|---|---|---|
| Mention | Your brand name appears in the answer text | Are we part of the conversation? |
| Citation | The engine links to a specific page as a reference | Did the engine trust our page enough to credit it? |
| Source | Any page the engine drew on, yours or not | Which sites shape what AI says about our category? |
Why the distinction matters
If you optimize for the wrong one, you waste effort. Chasing mentions is about being named and recommended; chasing citations is about being a trusted, linkable source; reading the source list is about understanding the information ecosystem that feeds the answers. AppearIn AI tracks all three separately so you can tell which problem you're actually solving.
