A Taxonomy of Research Visibility Indicators: From Discoverability to Knowledge Reach
The measurement of research visibility requires a systematic distinction between the underlying dimensions of visibility and the observable indicators used to represent them. Building on the ResearchTrics Research Visibility Framework established in ResearchTrics Research Bulletins Nos. 001-003, this bulletin develops a preliminary taxonomy of indicators for assessing the visibility of research outputs, researchers, research groups and institutions.
The taxonomy organises observable indicators across eight dimensions: discoverability, accessibility, scholarly recognition, engagement, connectivity, citation visibility, openness and knowledge reach. It distinguishes direct indicators, relational indicators, network indicators and contextual indicators, and proposes that indicators should not be interpreted as interchangeable measures of research value. Particular attention is given to metadata completeness, persistent identifiers, indexing, open access, researcher identity, downloads, citations, co-authorship, citation networks, disciplinary reach and geographical reach.
Recent evidence indicates that visibility-related concepts such as discoverability, findability and academic search-engine optimisation are frequently used inconsistently in the literature, supporting the need for clearer operational definitions. A 2025 scoping review of the digital-repository literature identified substantial conceptual overlap among these terms (Reyes-Lillo, Morales-Vargas, & Rovira, 2025). Recent research has also demonstrated the importance of metadata quality for discoverability and interoperability (Salauddin, 2026), while empirical work on ORCID has reported positive associations between ORCID-linked metadata and publication usage and citations among Arab university publications (Ibrahim & Ramzy, 2025).
The proposed taxonomy is intended as a conceptual measurement map rather than a finalised scoring system. Future research should establish the reliability, validity, independence, disciplinary comparability and fairness of individual indicators before they are incorporated into a composite Research Visibility Metric.
Research visibility has become increasingly important as scholarly communication moves from predominantly journal-centred dissemination toward interconnected digital research ecosystems.
A contemporary research output may be represented simultaneously through:
journal platforms institutional repositories scholarly search engines bibliographic databases persistent identifier systems researcher profiles citation indexes research networks data repositories software repositories professional or public communication channels
The result is an increasingly complex research-information environment. Research visibility therefore cannot reasonably be represented by publication counts or citation counts alone.
