For 15 years, marketing measurement got more precise every year. AI search is moving the other way. An assistant's recommendation happens in a conversation you can't see, and no platform will tell you what was asked. Michael closes out our four-part series on building a full-funnel AI search strategy with the measurement layer: which numbers you can get, why share of voice reads like a poll, and how to report to leadership that wants more certainty than the channel can give.

In this episode:

• Why AI assistants don't report like Search Console: the conversations are private, there's no site boundary to measure inside, and most assistants have no ad revenue riding on your click
• Hold the channel to the word-of-mouth bar. You can influence it, but you can't listen in
• The leading indicators from a prompt tracker: share of voice, mention rate, citation rate, and sentiment, by funnel stage and platform
• Share of voice is a sample, not a census, so your CEO's "we weren't in the answer" is one response in a poll
• The lagging indicators already in your stack: GA4's AI Assistant channel, organic conversion rate, direct traffic, branded search, and the how-did-you-hear-about-us field
• The monthly one-pager and quarterly narrative, labeled leading and lagging, with a note on what the report can't show
