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.
