# What is Citation gap?

A citation gap is the difference between how often AI systems cite one brand versus its competitors for the same set of buyer questions, exposing who owns the AI answer in a category and who is absent from it.

## How it works

You measure it by running the questions a real buyer would ask across the target engines and recording which brands appear. The gap is the distance between the leaders and everyone else, and in most B2B categories it is severe.

In rawmktg's teardowns the gaps were stark: a [39x ChatGPT citation gap in senior living](/blogs/india-senior-living-ai-visibility-gap), and [4 of 6 vendors in the AEC software space](/blogs/aec-ai-visibility-gap) with fewer than two AI citations combined. The pattern repeats because almost no one is competing for these citations yet.

## Citation gap vs ranking gap

A ranking gap compares positions in the classic search results. A citation gap compares presence inside AI-generated answers. A brand can have a small ranking gap and a huge citation gap, because being indexed is not the same as being cited.

## Why it matters for B2B

The citation gap is usually the clearest picture of a category's AI visibility, and it is often wide open. For a brand willing to move first, it is less a problem to fix than a moat to claim before competitors notice it exists.

**Common mistake**

Assuming strong rankings mean you are cited. Being indexed and being named in an answer are different events: a brand can rank on page one for its own category and still appear in none of the AI answers buyers actually read.
