The short answer
A citation gap is the difference between the sources an AI assistant cites when it names your competitors and the sources that cite or mention you. It shows where to earn coverage.

Why Citation Gap matters
The gap is a to do list: pages and publications the assistant already trusts that you are missing from.
How to measure or use it
List the sources cited for your questions, mark which of them mention each brand, and sort out those that mention competitors but not you.
How I handle it
This is the list I start the off site work from, and I only pursue sources where an honest case for coverage exists.

Citation Gap questions
Does closing the gap mean buying coverage?
No. It means earning it, with accurate information, useful data or a genuine reason to be included.
How often should I check it?
Monthly is enough. The cited sources for a question change slowly.
