Monitoring AI search means re-asking a fixed set of questions on a fixed cadence and recording which sources each engine cites. What makes it monitoring rather than a series of spot checks is that the prompt set does not change between runs.
What has to stay constant
Three things: the prompt set, the engine set, and the extraction rule for what counts as a citation. Change any one and the series breaks, because you can no longer tell whether a movement came from the market or from your own instrumentation.
This is the most common failure in AI-visibility reporting. A dashboard that quietly adds prompts each month will show improvement that is entirely an artefact of the added prompts.
Cadence and what it can detect
Perplexity in particular weights recency, so source sets move faster there than in AI Overviews. A weekly cadence catches source churn; a monthly cadence mostly catches structural change. Neither can detect a change smaller than the engines' own run-to-run variance, which is why observation count matters as much as frequency.
Below 40 distinct prompts our scorer will not call a difference reliable regardless of how often you run it. Frequency does not substitute for coverage.
Frequently asked questions
- How often should you check AI search visibility?
- Weekly if you are actively publishing or your category's source set churns; monthly is enough for stable categories. Cadence matters less than keeping the prompt set fixed — an inconsistent prompt set makes any cadence unreadable.
- Can I just watch my traffic instead?
- Analytics cannot see an answer that named you without a click, and most AI answers do not produce one. Traffic tells you about the clicks you won, not about the answers you appeared in.
- What counts as a citation when monitoring?
- Fix the rule before you start. We count a URL appearing in an engine's returned source list. Counting in-text brand mentions as citations inflates every number and is not comparable to anyone else's.
