Martech & Advertising · Machine Relations Index category
Which sources AI engines cite for Martech & Advertising questions
Vendor-owned sources earn 52.6% of classified citations in Martech & Advertising answers (2,061 of 3,920), as of November 2, 2026.
In the November 2026 release of the Machine Relations Index, these are the sources AI answer engines cited most often for each of the 7 Martech & Advertising question shapes, each ranked on that shape's own observed runs. This category has 7 observed question-shape segments in the current public release. Each segment keeps its own observed-run denominator and dates; this page does not average rates across shapes. Observed runs are answer runs, not questions: every segment repeats a small set of distinct questions across engines and dates, so a run count is not a count of independent questions.
