AI citation research
Studies I have run on how AI engines choose what to cite, listed only once they are live, with a short summary and a link to the full write-up. Studies published on the Wellows blog link there. What the findings change in practice is on my AI search optimization page.
What AI citation research has Khadija Zaman published?
Khadija Zaman has published a cross-engine AI citation overlap study on the Wellows blog covering January to June 2026, a re-test of that study against a permutation null that revised two of its headline findings, and a 94-day query fan-out experiment whose results were posted publicly by Wellows' COO. Each study states its data window and source.
