Rankings alone tell you where you stand in Google. They tell you nothing about whether ChatGPT names you. An AI mention scan alone tells you whether you were named in one query on one day. It tells you nothing about whether the fix will lift search alongside it. A schema audit tells you what is broken structurally. It tells you nothing about whether fixing it moves the numbers customers actually care about.
Each signal is a partial view. Correlation is evidence. The industry sells single-source dashboards because they are cheaper to run and easier to render as reports. That does not make them true.
We correlate three sources on every engagement. AI answers. Search performance. Site structure. A finding only becomes a recommendation when at least two of the three agree.
