NimbleSEO vs Ahrefs Brand Radar

Ahrefs Brand Radar is better at market-wide prompt demand: a 406M+ search-backed prompt corpus on the 110B-keyword Ahrefs graph that we do not have and do not claim to match. NimbleSEO differs on evidence rigor for YOUR cohort: confidence intervals with effective sample sizes, per-engine capture-mode disclosure, and an inconclusive label instead of a confident single number.
