ELI RESEARCH
AI-search source concentration: how narrow is the citation ecosystem?
Ten citations from ten publishers differ from ten citations from two domains.
Study methodology published; results pending.
RELEASE STANDARD
Methodology is publishable before findings are.
Eli can publish the question universe, schema, definitions and quality controls before a benchmark release. It will only publish an aggregate when the underlying observations are complete, reviewable and described with their coverage and limitations. Until then, this page makes no performance, ranking or customer-outcome claim.
What concentration means
Use top 1, 5 and 10 domain share, unique domains and long-tail count. Publish any concentration formula when implemented.
Domain vs URL concentration
Report both: one publisher can recur through multiple pages.
Future views
Compare engine, category, buyer stage, source type and ownership only when data meets thresholds.
