A claim clinic: what evidence is missing?

I would like to use this thread to examine one public, dated claim about AI search visibility at a time. Link the original source and separate its observation, inference and proposed action.

Then identify one missing piece of evidence that could change your assessment. Represent the author's caveats fairly. The purpose is to improve the test, not attack the person or sell a competing service.

Which claim would you like to examine together, and what would make you change your current view?
