AI Influence Index

Which sources drive
AI citations?

Every time an AI engine answers a B2B software query, it cites sources. This index ranks the 3rd-party sites — review platforms, forums, press, and encyclopedias — by how much influence they carry over those citations. Getting your brand listed on high-influence sources directly lifts your AI visibility.

How influence is scored: Each source receives a 0–100 composite score weighted across four signals — citation rate (40%, share of AI prompt runs that cited the source), position (30%, earlier citations score higher), engine breadth (20%, sources cited across more AI engines score higher), and stage coverage (10%, sources cited across more buyer-journey stages score higher).
