Citation Gap
The difference between the content AI engines cite for a question and the content your own site offers: the specific, missing pieces that keep you out of the answer.
Definition
A citation gap is what stands between you and a citation: for a given prompt, AI engines pull from competitor pages that have something yours doesn't: a comparison table, an FAQ section, concrete statistics, cleaner schema markup, more authoritative sources, or simply fresher content. Citation gap analysis is the practice of reading the pages that actually get cited, pinpointing those missing elements, and turning them into a prioritized list of fixes ranked by how much visibility each one can win back. Unlike a generic content audit, it's grounded in the sources AI is citing right now, so every recommendation maps to a real answer you're losing.
Example
A project-management tool finds that for "best Asana alternatives," every cited competitor page has a side-by-side feature table and a pricing FAQ: the two elements its own page is missing. Closing that citation gap is its highest-impact fix.
