Best APIs for GEO metrics: share of voice, position and sentiment
APIs that return per-brand share of voice, average position and sentiment, so you report on AI visibility without building the analysis.
By Mathias C.SEO consultant, and more recently GEO, at MentionBox

- Share of voice is relative to the brands in scope; visibility is the share of answers that mention a brand.
