What Prompt Set means
It should reflect how your category is actually asked about conversationally, which differs substantially from how people type into a search box.
Crucially it stays fixed. Changing questions between reports makes month-over-month comparison meaningless, and it's a common way agencies flatter results.
Why it matters for AI search
Without one, AI SEO is unfalsifiable. Screenshots prove nothing when models return different answers to the same question twice.
A well-built prompt set is also the single most useful artefact from an audit — it's yours to re-run independently at any time.
See it in action
Where the questions actually come from.
40–60 category prompts
Search query data
What people already type, rephrased conversationally
Sales conversations
The questions your team fields on every call
Competitor positioning
How rivals frame the category
PAA and fan-out
Sub-questions the topic decomposes into
Comparison intent
X vs Y, alternatives to X
Commercial intent
Pricing, implementation, who to hire
Six sources, one fixed set, approved before tracking starts.
Client approval matters. A set the agency chose alone can be quietly optimized for, which is exactly what makes the number meaningless.
How to get it right
Building a prompt set that measures something
- Draw from real query data, sales conversations and competitor positioning
- Phrase questions conversationally, in full sentences, as people actually ask them
- Get client approval before tracking begins, then freeze the set
- Run each prompt multiple times per cycle so variance is captured
- Revisit quarterly rather than ad hoc, and document any change
Common questions
How many prompts should be in a set?
Typically 40 to 60 for a focused category — enough to cover real question clusters, few enough to run reliably at multiple repetitions.
Why does the set have to stay fixed?
Because a changing set makes month-over-month comparison meaningless. It's also the easiest way to make results look better than they are.
Can we build one ourselves?
Yes. Start with the questions your sales team hears most, phrase them conversationally, and run them consistently. The discipline matters more than the tooling.
