Frequently asked questions about measurement

Why measure daily rather than weekly?

AI answers change continuously, with every model update and sometimes from day to day. Daily measurement makes the weekly comparison robust: outliers show up as outliers instead of distorting an entire week's evaluation.

Is measuring a single AI system enough?

No. The systems do not agree with each other: a brand mentioned in ChatGPT may be missing in Gemini or Claude. That is why we measure 6 engines in parallel rather than taking a snapshot from a single system.

Can I measure AI visibility myself?

Yes, with discipline: the same questions, without a login, documented and repeated over weeks. The fastest starting point is the free AI visibility analysis. It sets a first baseline you can build on.
