AMEC, the International Association for the Measurement and Evaluation of Communication, has launched a set of GEO principles aimed at measurement in the AI era, PRovoke Media reports.

The framework addresses what the association calls GEO — generative engine optimization — the practice of understanding and influencing how brands and messages appear inside AI-generated answers from tools such as ChatGPT, Gemini and Perplexity.

Why does this matter for practitioners?

Communications teams increasingly face a measurement gap. Traditional media monitoring captures coverage in outlets, but AI assistants synthesize answers from multiple sources and present them without links, timestamps or bylines. Standard clip-counting and reach metrics do not describe whether a client's key messages surface — accurately or at all — when a stakeholder asks a chatbot a question.

AMEC's move signals that the industry's main measurement body now treats AI-generated outputs as a category that belongs inside formal evaluation frameworks, alongside the Barcelona Principles that have anchored the discipline since 2010.

What are the GEO principles?

PRovoke's report confirms the launch itself but the published detail available at the time of writing centers on the announcement rather than the full text of the principles. Comms Memo will follow up with the complete framework once AMEC publishes the documents.

For practitioners, the questions the principles are expected to answer include:

• How to audit what generative engines currently say about a brand, executive or campaign;
• Which metrics credibly describe presence, sentiment and share of voice inside AI answers;
• How GEO results should be reported alongside earned, owned and paid channels;
• What standards prevent vendors from selling unverifiable "AI visibility" scores.

A crowded field, an unregulated one

The launch lands amid a surge of vendor activity. Measurement firms and PR tech companies have rushed out AI-visibility dashboards over the past two years, often with proprietary methodologies that clients cannot independently verify. An AMC-backed framework — AMEC counts most major measurement agencies among its members — could impose some discipline on claims that currently run ahead of the evidence.

Trade-press readers will recognize the pattern: every platform shift prompts a land grab of tools and terminology before standards bodies catch up. SEO went through the same cycle two decades ago. Whether these principles gain traction depends on adoption by AMC's member agencies and, more importantly, by in-house clients who demand GEO reporting in briefs and RFPs.

What happens next?

Watch for AMC member agencies building the principles into their measurement frameworks, and for the first case studies that test whether GEO measurement holds up under scrutiny. Comms Memo will report on the full principles document, and on how measurement teams apply them, as details emerge.
