# Source Citation

## Quick answer

A source citation is the specific page, review or article an AI answer engine points to as the basis for a claim it makes about a brand, the way a search result shows the page a snippet was pulled from. Knowing which sources get cited is the difference between guessing why an answer said what it said and actually knowing.

## Why it matters

If an AI engine keeps citing an outdated review or a competitor's comparison page instead of a brand's own current pricing page, that engine's description of the brand will stay wrong until something changes what it cites, not just what the brand's own site says. Source citations are the lever: they show exactly which page is winning the engine's trust for a given question, so a brand knows what to fix, update or outrank rather than reacting to the wrong fact in isolation.

## How to measure it

Ask an AI engine a brand's target buying question and record which URLs it names or implies as its source, repeated across the engines a brand's buyers actually use. Over several weeks this builds a picture of which of a brand's own pages get cited, which competitor or third-party pages get cited instead, and whether a newly published or recently updated page starts showing up as a source in later checks. Tracking this per engine matters too, since one engine citing a brand's page doesn't mean another engine has started to as well.

## Example

A help-desk tool asks "what does [vendor] cost" across several AI engines and finds two of them citing a two-year-old review site article with an outdated price, rather than the vendor's own current pricing page. The fix isn't to argue with the engine; it's to make the vendor's pricing page the more citable source, since the review article is simply more specific and easier to lift an answer from than the vendor's current page is. A clearer, more direct pricing page, rewritten with the exact question in mind, is what eventually displaces the outdated source.

## FAQ

### Does every AI engine show its sources the same way?

No. Some name the source URL directly in the answer, others only imply it or list it separately, so tracking citations means checking each engine's own format rather than assuming one approach works everywhere.

### Can a brand control which page gets cited?

Not directly, but a brand can make its own page the more citable one by answering the exact question more directly and keeping the facts current, which tends to outcompete a vaguer or outdated third-party source.

### Is a source citation the same as a backlink?

No. A backlink is a link from one page to another regardless of context; a source citation is specifically the page an AI engine draws a stated fact or claim from when answering a question.
