How Cora SEO Software measures what ranks
Cora, built by Ted Kubaitis at SEO Tool Lab, collects the top 100 Google results for a keyword, measures up to 2,040 on-page and off-page ranking factors on each of them, and then uses Pearson and Spearman correlation to show how strongly each factor moves with rank position. The output includes the SEO Road Map, Basic and Intermediate Tunings, and measurement data with a chart for every factor. Because the correlations are recalculated on every run, a new report reflects how Google currently rewards each factor. Cora Diff compares reports from before and after an algorithm update, and Cora Trends finds the factors a group of keywords share. Correlation is evidence of what ranks, not proof of what causes ranking, so treat Cora’s output as prioritized hypotheses to test.

- Breadth of signals: structural, technical and off-page factors, not only topical coverage.
- Update response: Cora Diff compares reports before and after a Google update.

Where MarketMuse is the better fit
- MarketMuse is better at planning topic clusters and measuring topical authority across an entire site, which Cora does not try to do.
- Its briefs help writers get started; Cora produces an optimization Road Map, not a writing brief.
- Its free tier is useful for light use.
