Entity confidence is not a measure of business quality per se, but of the legibility and coherence of the signals from which AI systems must form their assessment. This paper presents a formal definition of entity confidence as a measurable construct describing the degree to which artificial intelligence systems are able to identify, interpret, and evaluate a named entity – typically a business or organisation – as a credible, coherent, and recommendable subject. Entity confidence exists on a continuous spectrum: from conditions of near-complete ambiguity, in which an AI system is unable to reliably distinguish or describe an entity, to conditions of high fidelity, in which the system holds a stable, multi-source, internally consistent representation sufficient to support confident recommendation. Entity confidence does not refer to an internal probability score produced by an AI model; it describes the external informational conditions that enable AI systems to construct reliable representations of entities from publicly available digital evidence. The concept addresses a gap in the existing vocabulary for AI-era business visibility. While frameworks such as Google's E-E-A-T describe quality signals within a single platform's ranking algorithms, entity confidence describes a more fundamental property: the degree to which any AI-powered system can construct a reliable representation of an entity from the available digital evidence. Entity confidence is therefore not a measure of business quality per se, but of the legibility and coherence of the signals from which AI systems must form their assessment. This definition is published to establish a clear, citable reference point for the concept and to encourage further research and discussion within the professional and academic communities. The authors' organisation, Entity Confidence Ltd, has developed a proprietary assessment methodology that operationalises this definition; the details of that methodology are commercially confidential and are not disclosed in this paper.
