What Is Webometrics? History, Origins and Academic Foundations

Webometrics is the quantitative study of the construction, structure, use and impact of information on the World Wide Web. The field developed from informetrics and bibliometrics, and the term entered peer-reviewed academic literature in 1997 through the work of Tomas C. Almind and Peter Ingwersen. University ranking later became one application of the broader field. [1] [4] [7].

From informetrics and bibliometrics to Web Impact Factors, link analysis and web indicators for university evaluation, and how WEBOMETRICS by UNIRANKS applies the field today.

The word Webometrics is today frequently encountered in discussions about university rankings, academic visibility and institutional performance on the Web. Yet the history of the term begins somewhere quite different.

Webometrics did not originate as the name of a university ranking.

It emerged from academic research into how quantitative methods traditionally used to study scholarly information and scientific communication could be applied to the rapidly expanding World Wide Web.

The historical record is unusually clear.

In 1997, Tomas C. Almind and Peter Ingwersen published a peer-reviewed article in the Journal of Documentation titled “Informetric Analyses on the World Wide Web: Methodological Approaches to ‘Webometrics’.” The article explicitly introduced the application of informetric methods to the World Wide Web under the term Webometrics. [1]

Fifteen years later, webometrics scholar Mike Thelwall reviewed the development of the discipline and explicitly wrote that the term had been coined by Almind and Ingwersen in 1997. [7]

This chronology matters. Understanding that distinction is essential to understanding what Webometrics actually is.

Webometrics could only emerge after the Web itself had developed into a sufficiently large information environment to study quantitatively.

Tim Berners-Lee proposed what became the World Wide Web at CERN in 1989. Development of the first WorldWideWeb browser/editor followed in 1990, and Web technology began becoming available over the Internet in 1991. [8]

During the following years, the Web expanded from a relatively small technical information environment into an international publishing and communication system.

That transformation created an entirely new object of research. Researchers could begin asking questions such as:

• How large are different parts of the Web?
• How are websites interconnected?
• What can hyperlinks reveal about relationships between organizations?
• Can Web visibility be measured?
• Can methods developed for bibliographic databases be adapted to Web information?
• Can online structures provide evidence about scientific communication, institutional activity or social behavior?

These questions ultimately formed part of the intellectual environment from which Webometrics developed.

Webometrics did not emerge in isolation. Its intellectual foundations are closely connected to bibliometrics, informetrics and scientometrics.

Bibliometrics applies quantitative techniques to publications and related information, such as citations. Scientometrics focuses particularly on quantitative aspects of science, research and scientific communication. Informetrics is broader, encompassing quantitative study of information production, distribution and use.

The Web presented researchers with a new information environment containing pages, documents, hyperlinks, domains, organizations, authors and rapidly growing networks of digital communication.

The question became whether some of the analytical ideas developed in these older disciplines could be adapted to this new environment. That is precisely the context in which Webometrics appeared.

Björneborn and Ingwersen later formalized this relationship in their influential 2004 paper “Toward a Basic Framework for Webometrics.” They explicitly placed Webometrics within informetric and bibliometric research and discussed its relationship with cybermetrics. [4]

Mike Thelwall similarly described Webometrics as arising through the application of bibliometric and informetric approaches to Web-based information, structures and technologies. [7]

The pivotal publication appeared in 1997.

Tomas C. Almind and Peter Ingwersen published “Informetric analyses on the World Wide Web: methodological approaches to ‘webometrics’” in Journal of Documentation, Volume 53, Issue 4, pages 404–426. DOI: 10.1108/EUM0000000007205. [1]

The article was peer reviewed. Its abstract describes the research directly: it introduces the application of informetric methods to the World Wide Web and identifies this approach as Webometrics. The authors used a case study of Web content associated with Denmark and other Nordic countries and compared their methodological approach with traditional bibliometric analyses. [1]

This is important evidence because the historical argument does not depend on later interpretations of the term. The original 1997 academic record itself establishes the usage.

Thelwall’s later historical review provides independent scholarly confirmation. His 2012 article “A History of Webometrics” states explicitly that Almind and Ingwersen coined the term in 1997 in recognition that informetric analysis could be applied to the Web. [7]

The earliest Webometric work was experimental. The Web of the late 1990s was very different from today’s Web.

Researchers relied heavily on commercial search engines because the huge data infrastructures available today did not yet exist. Pages, domains, hyperlinks and files therefore became measurable proxies through which researchers could investigate the emerging Web.

One particularly influential idea was the Web Impact Factor.

In 1998, Peter Ingwersen published “The Calculation of Web Impact Factors” in the Journal of Documentation. [2]

The concept drew inspiration from citation-based impact measures in scholarly publishing. Instead of asking how frequently academic publications were cited, Web Impact Factor research explored whether hyperlinks pointing toward websites or Web domains could provide a useful measure of their impact or visibility.

Ingwersen investigated national Web domains, sector-level domains and institutional websites. His analysis also documented an important methodological reality of early Web research: results depended on search-engine data and therefore had measurement limitations. [2]

Thelwall later identified the Web Impact Factor as one of the developments that helped establish Webometrics as a recognizable research field. [7]

This represented an important conceptual transition. A hyperlink was no longer viewed simply as a technical mechanism for navigating from one page to another. Researchers began investigating whether aggregate hyperlink patterns could reveal something about:

• visibility
• authority
• relationships
• scholarly communication
• organizational networks
• information flows
• academic influence

But researchers also increasingly recognized that hyperlinks and scholarly citations were not equivalent. That distinction would become important as the field matured.

Webometrics rapidly expanded beyond raw hyperlink totals.

By 2001, Lennart Björneborn and Peter Ingwersen were examining broader theoretical perspectives involving Web structures and network analysis in “Perspective of Webometrics,” published in Scientometrics. [3]

In 2004 they published what became one of the field’s most important conceptual papers: “Toward a Basic Framework for Webometrics.” The paper sought to establish more consistent terminology for Web nodes and links while placing Webometrics clearly within the broader family of quantitative information disciplines. [4]

Importantly, the authors warned researchers against carrying the analogy between hyperlink analysis and citation analysis too far. That warning remains methodologically significant.

A hyperlink can be created for countless reasons. A citation in an academic article operates within a more structured scholarly convention. Both can provide useful evidence, but they represent different forms of behavior.

Modern Webometric evaluation therefore cannot responsibly assume that every link is equivalent to an academic citation.

As the field matured, the meaning of Webometrics broadened. It encompassed not only link measurement but quantitative research into the construction, structure, use and impact of Web-based information.

The substantial review by Mike Thelwall, Liwen Vaughan and Lennart Björneborn published in the Annual Review of Information Science and Technology documented the breadth the field had acquired. [5]

Research included areas such as:

• hyperlink analysis
• Web citation analysis
• search-engine measurement
• academic Web networks
• institutional Web structures
• information dissemination
• scholarly communication
• Web usage
• quantitative analysis of online communities

Another term that became important is cybermetrics. The two concepts overlap but are not necessarily identical.

Björneborn and Ingwersen’s framework associated Webometrics with the broader area of cybermetrics while locating it within informetric and bibliometric research traditions. [4]

Cybermetrics can encompass quantitative measurement of Internet-based phenomena extending beyond the Web itself. Webometrics concentrates more specifically on Web-based information, structures and technologies.

In practice, historical literature sometimes uses these terms with overlapping meanings.

Universities were natural objects for Webometric analysis. By the early 2000s, universities had developed substantial Web domains containing institutional information, academic department pages, research documents, repositories, academic profiles, conference materials, teaching resources, publications and administrative information.

Their websites represented part of their academic and institutional activity. Researchers therefore began investigating whether quantitative Web indicators could help describe differences between universities.

A 2006 study analysed 9,330 institutions worldwide using web-based indicators. [6]

The researchers obtained measures including website size, external inlinks and rich files and investigated whether these indicators could contribute to describing and ranking university activities. The paper found relationships between Web-based indicators and other measures of university activity while also arguing that cybermetric approaches could provide visibility for institutions and regions inadequately represented by conventional citation-based datasets. [6]

This was a significant development in the application of Webometric research to higher education evaluation.

This distinction helps prevent much of the confusion surrounding the word Webometrics. There are four distinct layers that should be kept separate when discussing the history and present-day use of Webometrics:

1. Webometrics as an academic field

This is the broader scholarly discipline concerned with quantitative analysis of Web information, structures, relationships, use and impact. Its documented academic history reaches back to the 1990s.

2. Webometric university evaluation

This is an application of Webometric approaches to higher education institutions. Many different variables, datasets and mathematical models could potentially be used to implement such an evaluation.

3. A specific Webometric university ranking

A ranking organization may select particular indicators, weights, databases, domain-identification rules, collection periods, normalization methods and inclusion criteria. That combination constitutes a particular implementation.

It should not automatically be equated with the entire academic field from which some of its methods originate.

This principle is common across research. Bibliometrics is not one citation database. Econometrics is not one economic ranking. Scientometrics is not one research-index provider. Network science is not one network-analysis product.

Likewise, Webometrics is broader than one university-ranking implementation.

4. WEBOMETRICS by UNIRANKS as a contemporary application

WEBOMETRICS by UNIRANKS is a university-ranking and research initiative, developed and operated by UNIRANKS Inc., that applies the academic concept of webometrics to contemporary university evaluation. webometrics.org is its public website and publication platform. UNIRANKS develops its own data systems, institutional identification processes, methodology, collection cycles, normalization procedures and ranking publications for WEBOMETRICS. It is a contemporary application within the broader academic tradition of webometrics, not another name for the academic field itself.

The technology available to Almind, Ingwersen and other early researchers was necessarily limited by the Web infrastructure of their time. The same applies to early university-ranking systems.

Search engines have changed. Link databases have changed. Institutional repositories have expanded. Research graphs have become vastly larger. Persistent identifiers have become more important.

Modern researchers can potentially work with data infrastructures such as:

• large backlink indexes
• scholarly knowledge graphs
• institutional identifiers
• citation databases
• repository metadata
• academic profiles
• domain intelligence
• structured Web data

The history of Webometrics therefore should not be interpreted as requiring contemporary researchers to reproduce exactly the technological techniques available in the 1990s and 2000s.

The history of webometrics does not end with the early scholarly literature. The field continues to be applied through new research, data and evaluation systems.

WEBOMETRICS by UNIRANKS is a global university ranking and research initiative, independently developed and operated by UNIRANKS Inc. It applies webometric and bibliometric principles to evaluate how institutions are represented, referenced and recognised on the web and in scholarly communication, across three published dimensions: Impact (50%), Excellence (40%) and Openness (10%).

UNIRANKS independently collects, validates and processes the indicators behind WEBOMETRICS through its own data infrastructure, drawing on academic research and scholarly publication data, citation indicators, web visibility and link intelligence, automated collection systems and APIs, and licensed external data services where applicable. Each edition is calculated according to the methodology published on webometrics.org, applied in the same way to every eligible institution.

WEBOMETRICS forms part of the wider UNIRANKS ecosystem, alongside initiatives such as Open Index and OnePath. Each has a distinct function: WEBOMETRICS focuses on webometric university evaluation; Open Index supports large-scale academic and research data activity; and OnePath focuses on student guidance and university engagement. Paid UNIRANKS services are separate from ranking evaluation and do not influence ranking scores or positions.

WEBOMETRICS by UNIRANKS is a modern application of the academic concept of webometrics. It does not claim to have originated the field; its credibility rests on its published methodology, its data and its transparency.

Terminology matters because it affects how universities, researchers, students, journalists and digital systems interpret information.

Understanding the history of the field helps readers evaluate any ranking built on it. Useful questions include:

• who operates the ranking
• what methodology it publishes
• which data it uses
• how institutions are identified
• whether its calculations can be examined
• how corrections are handled
• whether organizational relationships are disclosed
• whether results can be independently checked

These are the standards WEBOMETRICS by UNIRANKS aims to meet.

The documentary record provides a clear answer to the question “What is Webometrics?”

Webometrics is a field of quantitative research concerned with studying the Web using approaches originating particularly from informetrics and bibliometrics.

The term entered peer-reviewed academic literature through the landmark 1997 article by Tomas C. Almind and Peter Ingwersen. [1]

The field subsequently expanded through research including Peter Ingwersen’s Web Impact Factor, Björneborn and Ingwersen’s theoretical frameworks, Mike Thelwall and colleagues’ extensive Web research, and the development of cybermetric approaches to scientific communication. [2–5, 7]

University evaluation arrived later as one application of these ideas, building on research that tested web indicators for institutions worldwide. [6]

Today, WEBOMETRICS by UNIRANKS applies this academic tradition to contemporary university evaluation through its own methodology, data systems and publication practices, published on Webometrics.org. It should be evaluated on the evidence supporting that methodology and data.

Webometrics is an academic field. Webometric university evaluation is an application of that field. WEBOMETRICS by UNIRANKS is a contemporary ranking that applies it, developed and operated by UNIRANKS Inc., with Webometrics.org as its public website and publication platform.

Keeping these concepts separate provides a stronger foundation for understanding both the history of Webometrics and its continuing evolution.
