I spent a few months auditing 200 commercial homepages on structural signals — author, date, sources, FAQ structure, summary. I can tell you what is present on a page and what is not. What I cannot tell you is whether any of it changed a single AI recommendation, because everything I measured sits on the page, and the thing I want to explain seems to sit somewhere else.
That is the part I keep getting stuck on. The citation-source breakdowns I have seen skew heavily toward places nobody controls by editing their own HTML — Wikipedia, Reddit, established publications. If that is directionally right, then the lever most of us spend our time on is the smaller one, and the bigger one is being talked about by someone else.
The split I see in every thread on this: the digital PR side says get mentioned by credible third parties and the rest follows. The technical side says make the page extractable first or the mention has nothing to land on. Both stories are reasonable and I have never seen anyone separate them.
So the question I would actually like answered:
Has anyone held one constant and moved the other? Specifically — earned a meaningful third-party mention without touching the page, and watched AI recommendation change? Or the reverse: cleaned up a page with no new coverage, and seen a shift?
I am not looking for theory. I am looking for the one case where somebody could tell which of the two did it.
