# Citations
> See which domains and pages AI shopping engines cite when recommending products in your market, and find the sources worth earning.
## Overview
When AI shopping engines recommend products, they draw on sources from across the web: reviews, buying guides, retailer pages, and more. The Citations page shows you exactly which sources they're citing in your market, so you can earn a place among them.
## Where AI gets its information
* **Source mix**: citations grouped by site type (commerce, publisher, social, review, brand sites)
* **Content signals**: citations grouped by page type (product pages, articles, reviews, category pages, and more)
Together these tell you what *kind* of content is shaping recommendations on your shelf.
## Top sources
* **Top domains**: the domains cited most often in your market, ranked by frequency
* **Most cited URLs**: the individual pages that come up again and again
* **Domain lookup**: click any domain to see its per-page breakdown and which of your products it's associated with
## Your content vs. the gaps
Citations distinguishes your **own** pages that get cited from sources where competitors appear but you don't, a direct list of content opportunities. Pair this with [Content](/shopping/content/blog) and [Collection Pages](/shopping/content/collections) to close the gaps.
