AMEC sets measurement standards for AI-driven search and discovery
AMEC, the international communications measurement body, has launched a framework to help PR and communications professionals measure how organisations appear in AI-generated answers and conversational search results.
The AMEC GEO Principles - GEO stands for Generative Engine Optimisation - address a practical problem: clients and boards are asking how to measure visibility in large language models and AI discovery tools, but no consistent standards exist yet.
The framework divides measurement into three areas. First, upstream reputation signals: earned coverage, third-party commentary, reviews and owned assets. Second, search and content readiness: whether an organisation's digital presence is credible and structured for AI interpretation. Third, downstream AI outputs: how an organisation actually appears in AI-generated answers, citations and framing.
AMEC also published A Practitioner's Guide to GEO Measurement alongside the principles. Both resources emphasise treating AI outputs as directional evidence rather than absolute truth, and warn against relying on any single score or tool.
Who built this and why
The principles were developed over six months by a group led by James Crawford of PR Agency One, Mary Elizabeth Germaine of Ketchum, Ben Levine of FleishmanHillard TRUE Global Intelligence, and others. Input came from AMEC's Academic Advisory Group and members across more than 80 countries.
Crawford said the industry currently has "uneven standards, overclaiming, vanity metrics and methodologies that are not always transparent enough." AMEC's framework aims to bring discipline to measurement without reducing it to simplistic rankings.
The resources were launched at the AMEC Global Summit in Dublin on 20 May.
What this means for practitioners
The principles introduce baseline evidence requirements: repeatable prompts, documented methods, transparent assumptions and clear limitations. The guidance cautions against treating any single platform's output as definitive.
Johna Burke, CEO of AMEC, said: "As AI increasingly shapes what people see, trust and act upon, the communication industry must hold itself to higher levels of transparency, evidence and accountability."
For PR professionals, this means building measurement around three connected areas rather than chasing rankings in individual AI tools. The framework recognises that reputation signals, technical readiness and actual AI outputs all matter - but none tells the full story alone.
