What is AI citation rate?
The percentage of tracked answer opportunities in which your domain is cited.
AI citation rate measures how often your domain receives a source link across a defined set of prompt-and-engine checks. The basic formula is citations ÷ eligible answer checks × 100.
Always report the denominator, engine mix and time window. A 40% rate can mean four citations from ten checks or 400 from 1,000; those results have very different reliability. Track citation rate by topic, funnel stage and engine before rolling it into one headline number.
Why — and when — does it matter?
Citation rate normalizes raw citation counts by opportunity, making periods and segments comparable when the denominator is stable and disclosed.
How it works
Define an eligible answer check as one prompt on one engine in one run.
Exclude failed or non-answer responses using a stated rule.
Count checks containing at least one citation to your domain.
Divide by eligible checks.
Segment by engine, topic and funnel stage.
Worked example
A site is cited in 18 of 60 eligible checks: 30%. ChatGPT is 45% while Gemini is 15%, so the engine breakdown is more actionable than the blended rate.
How to track and report it
Reporting rule: State the engine, prompt set, market, time window and denominator. A number without scope cannot be reproduced or compared.
Practical playbook
- Define an eligible answer check as one prompt on one engine in one run.
- Exclude failed or non-answer responses using a stated rule.
- Count checks containing at least one citation to your domain.
- Divide by eligible checks.
- Segment by engine, topic and funnel stage.
Common mistakes
- Reporting a percentage without its denominator
- Counting multiple links in one answer as multiple wins
- Comparing different prompt sets

How do you measure AI citation rate?
Cited checks and eligible checks. Confidence, sample size and rate by segment. Citation rate = cited checks ÷ eligible checks × 100
What is a common mistake with AI citation rate?
Reporting a percentage without its denominator. The scope and methodology should be stated before interpreting the result.
