When ChatGPT and Google AI Overviews describe a brand in negative terms, the fix runs through metrics and a repeatable process. This page covers the net sentiment score formula, negative mention rates by engine, the distribution of what triggers negative tone, what each measurement tool publishes, and a four-step method for swapping the evidence layer.

The IAB's August 2026 AI visibility measurement standard defines Four Ps: Presence, Prominence, Portrayal, and Persuasion, along with two data quality tiers and vendor disclosure requirements. This page covers the full framework, an industry concentration breakdown, a tool comparison, and a brand execution roadmap.

A diagnostic breakdown of why ChatGPT, Perplexity, and Google AI Overviews cite competitors while your brand goes unmentioned: covering crawler access, machine readability, entity recognition, third-party mentions, and content structure, with a step-by-step fix for each.
