Why this dimension exists
Statistics, quotations and cited sources are the interventions with the largest measured effect in the published GEO research.
Why it carries 11%
High and research-driven: this is the dimension most directly tied to measured visibility gains.
The rules it is scored by
Each rule is a single question the scanner asks about a page. Passing one adds its share of this dimension; failing it takes that share away. Every rule links to what it looks for and what evidence passes it.
- Body text contains at least 5 numeric claims: percentages, currency amounts, multipliers of the form 3.2x, thousands-separated figures, or raw numbers of five digits or more. A bare four-digit number is not counted, because it is a year far more often than it is a finding.4.0%
- The page contains at least one <blockquote> element.3.0%
- The page links to at least 2 external hosts on the authority list: arxiv.org, doi.org, nature.com, science.org, acm.org, ieee.org, springer.com, sciencedirect.com, any .gov or .edu host, wikipedia.org, github.com, developer.mozilla.org, web.dev, nih.gov, who.int or europa.eu. Own-domain links are excluded.3.0%
- The page declares a rel=canonical link.1.0%
What this dimension cannot tell you
A single-URL scan reads one page. It cannot see the rest of the site, it cannot see how a model behaves over time, and it cannot see whether the page is actually cited for the queries that matter. Those are the parts of the picture a score of this kind is blind to, and they are listed in full on the methodology page rather than implied here.
