What RankGear measures

RankGear catalogues 928 factors across 24 families, each tested for how it correlates with position across the field for your query. How many are measured on any given run depends on the result set — a factor counts as measured when it returns a value for your page and its comparison set. A few are minted at runtime from the field itself, so the exact count varies by run.

The 24 families

Factors are grouped by what they describe. The largest families reflect where measurable signal lives on modern result pages:

  • Structured data · JSON-LD (269) and MicroData (49), MicroFormat (24), Schema.org (28)
  • Keyword usage & density (101)
  • Headings (51) and Search result / SERP (51)
  • Social signals (39), Tech & platform (34), Affiliate & ads (31)
  • Size & length (25), Links on the page (24), Meta tags (24)
  • Backlinks & authority (23), Title (21), Entities (19)
  • Readability & questions (16), Related terms / LSI (11), Trust & contact signals (10)
  • Page structure (9), Media & embeds (8), URL & domain (3)

Why the count is honest, not marketing

A large catalogue is only useful if the numbers stay comparable. Every factor maps to a stable Factor ID, so a run in March and a run in June measure the same thing — which is what lets Diff and Trends show real movement instead of re-derived noise.

Correlation, not causation. Measuring 928 factors doesn’t mean maximizing all of them. Most matter for some queries and not others; RankGear shows which ones track position in your field, and by how much.

For the full method — correlation, deficit strategies, and boundaries — see the methodology page. In the app, “What RankGear measures” writes the complete factor reference as its own report.
