What is a citation source?
A citation source is a web page or domain that an AI assistant links to as evidence for an answer. Looking at the sources behind the answers for your questions shows where assistants get their information about your category, and which of those pages you could appear on or improve.
How to use it
List the most-cited domains for your questions. Each is either a page you should be on (a roundup, a review platform), a competitor's page, or your own. Gaps tell you where to publish or ask for a correction.
Example: for "best project tool for agencies", assistants link three roundups and one review platform; those four domains are your citation sources.
