How is the Altmetric Attention Score Calculated?
The Altmetric Attention Score is a weighted measure that reflects the online attention a research output, such as a journal article or dataset, has received. It aggregates data from various sources like social media, news outlets, policy documents, blogs, and online reference managers. The score is represented as a single numerical value and is often visualized as a colorful “donut.”
Key Factors in the Altmetric Attention Score Calculation
- Volume of Mentions:
- The more mentions an article receives, the higher its score. Each mention from a recognized source contributes to the score, but excessive repetition from the same source is weighted less heavily to avoid manipulation.
- Sources of Mentions:
- The score incorporates mentions from multiple platforms, such as:
- Social Media: Tweets, Facebook posts, and LinkedIn shares
- News Outlets: Coverage in media articles
- Policy Documents: Mentions in government or institutional policy reports
- Blogs: References in academic or non-academic blogs
- Online Reference Managers: Saves in tools like Mendeley
- Each source is weighted differently based on its reach and influence.
- The score incorporates mentions from multiple platforms, such as:
- Weighting by Source Type:
- Different sources contribute differently to the score. For example:
- News mentions have higher weight because of their potential broad audience and societal impact.
- Social media mentions, while more numerous, are weighted less because they are often seen as less formal and easier to generate.
- Policy documents carry significant weight as they indicate real-world application of the research.
- Different sources contribute differently to the score. For example:
- Authoritative Sources:
- Mentions from authoritative and credible accounts (e.g., official government bodies and reputable journalists) are given more weight compared to non-authoritative or less credible sources.
- Geographical Diversity:
- The score also considers the geographical diversity of mentions. A research output discussed in multiple countries may receive more attention than one restricted to a single region.
- Time Decay:
- Older mentions contribute less to the score over time. This ensures that the Altmetric Attention Score reflects the current level of interest in the research output.
Interpreting the Altmetric Attention Score:
The Altmetric Attention Score is not an indicator of the quality or rigor of the research but rather its online visibility and engagement. A high score suggests that the research has captured significant attention across various platforms, while a low score indicates less visibility. The colorful Altmetric “donut” visually represents the breakdown of sources contributing to the score, with different colors corresponding to different platforms.
By combining data from diverse sources and weighting them appropriately, the Altmetric Attention Score provides a nuanced picture of how research resonates with academic and non-academic audiences alike.

Can Altmetrics Be Manipulated, and How Can This Be Mitigated?
Altmetrics, like any metric, can be susceptible to manipulation due to their reliance on publicly available online data. Researchers or other stakeholders might attempt to artificially inflate Altmetric scores by exploiting the platforms and sources that contribute to these metrics. For instance, excessive self-promotion on social media, coordinated sharing by networks of supporters, or the use of automated bots to generate fake likes, retweets, or mentions can skew the perceived attention a research output receives. Similarly, unethical practices such as creating multiple accounts on reference managers like Mendeley to save the same article repeatedly or paying for favorable media coverage can distort Altmetric scores, giving an inaccurate impression of societal engagement.
To mitigate such risks, Altmetric platforms must adopt robust mechanisms to identify and filter inauthentic activities. Algorithms can be designed to detect unusual patterns, such as rapid spikes in mentions from newly created accounts or repetitive activity from the same source. Weighting metrics by the credibility of the source is another effective strategy; for example, mentions from reputable media outlets, government policy documents, or institutional blogs should carry more weight than activity from unverified or less reliable accounts. Additionally, platforms should prioritize transparency, providing detailed reports on the origins and nature of the data contributing to Altmetric scores, enabling users to distinguish between genuine and artificial engagement.
Educating researchers about the ethical use of Altmetrics is equally important. Encouraging responsible self-promotion and emphasizing organic engagement can help maintain the credibility of these metrics. Independent audits and regular monitoring of Altmetric scores can further ensure their integrity by identifying potential manipulation patterns and addressing them promptly. By implementing these measures, altmetrics can continue to serve as a reliable tool for assessing the societal and online impact of research in an increasingly digital world.
What Are the Limitations of Using Altmetrics as a Primary Measure of Research Impact?
Altmetrics provide valuable insights into the online attention and societal engagement of research, but they come with several limitations that make them unsuitable as a sole or primary measure of research impact. Here are the key limitations:
- Lack of Standardization: One of the primary limitations of Altmetrics is the absence of standardization. Different Altmetric platforms use varying methods to collect and evaluate data, resulting in inconsistencies across scores. For example, one platform might prioritize Twitter mentions, while another gives more weight to policy document citations. This variability makes it difficult to compare Altmetric scores reliably, raising questions about their validity as a universal measure.
- Vulnerability to Manipulation: Altmetrics are highly susceptible to manipulation. Researchers or supporters can artificially inflate scores through excessive self-promotion on social media, coordinated sharing within networks, or the use of automated bots to generate fake likes, retweets, or mentions. Such practices can create a distorted picture of a research output’s true engagement and impact, undermining the credibility of Altmetrics as an objective measure.
- Focus on Popularity Over Quality: Altmetrics tends to measure the visibility or popularity of research rather than its scientific rigor or quality. A study that garners significant online attention might do so because of controversial or sensational claims rather than its academic merit. Conversely, high-quality but niche research might not receive the same level of attention, leading to undervaluation of its impact.
- Short-Term Perspective: Altmetrics provide real-time insights into online engagement, but they often capture only the immediate attention a study receives. This short-term focus may fail to reflect the long-term significance of research, which often takes years to accumulate citations and influence its field. Groundbreaking studies that shape academic thought over decades may appear less impactful through the lens of Altmetrics.
- Disciplinary Disparities: Altmetrics are not equally applicable across all academic disciplines. Research in fields with a natural public or media appeal, such as health, technology, or climate change, is more likely to generate online attention. In contrast, work in theoretical or niche fields, such as pure mathematics or philosophy, may struggle to gain similar visibility, leading to skewed assessments of research impact.
- Limited Context: While Altmetrics provides quantitative data on the number of mentions or shares, they often lack qualitative context. For instance, a high number of social media mentions might reflect controversy, criticism, or misinformation rather than genuine engagement or positive societal influence. Without understanding the nature of the discussions, altmetrics can give a misleading picture of the research impact.
- Digital Accessibility Bias: Altmetrics relies on the online visibility of research outputs. Studies published in open-access formats are more likely to attract Altmetric data than those behind paywalls, regardless of their quality or importance. This creates a bias that favors digitally accessible research and may disadvantage work published in traditional formats or less digitally engaged regions.
- Dependence on Platform Algorithms: The visibility of research online is heavily influenced by the algorithms of social media platforms and search engines. These algorithms prioritize content based on engagement metrics, which might not align with the relevance or quality of scholarly work. This dependence introduces unpredictability and potential bias into Altmetric scores.
- Lack of Peer Review: Altmetrics does not account for the rigor of peer review, a cornerstone of academic validation. A study with high Altmetric scores may not have undergone stringent quality checks, making it difficult to differentiate between robust research and work that gains attention for less rigorous reasons.
Altmetrics provides a valuable perspective on how research is received and discussed digitally, offering insights into its societal and online reach. However, their limitations make them unsuitable as a standalone measure of research impact. They are best used in conjunction with traditional metrics, such as citation counts and peer-reviewed assessments, to provide a more comprehensive evaluation. By recognizing the strengths and weaknesses of Altmetrics, researchers, and institutions can leverage them responsibly, ensuring they complement rather than replace established methods of assessing academic contributions.
How Can Researchers Improve Their Altmetric Scores Without Compromising the Integrity of Their Work?
Improving Altmetric scores while maintaining the integrity of academic work requires a strategic and ethical approach that focuses on enhancing visibility, accessibility, and societal relevance. A key step is to publish in open-access formats, ensuring research is freely available to a global audience. Open-access articles are more likely to be shared and cited by academics, policymakers, and the general public as they remove barriers to access. Researchers can also share their work on social media platforms like Twitter, LinkedIn, and Facebook, using engaging summaries or infographics to make their findings accessible and appealing to a diverse audience. Participating in online discussions within their research community further increases visibility and fosters authentic engagement.
Another effective strategy is to create content tailored for non-specialist audiences. Writing blog posts, summaries, or opinion pieces in layman’s terms helps communicate complex research findings to broader audiences, increasing the likelihood of online sharing and mentions. Visual and multimedia content, such as infographics, videos, or slide presentations, can also make research more digestible and shareable, amplifying its online presence. Researchers should consider collaborating with science communicators or media professionals to refine their messaging and maximize the impact of their outreach efforts.
Engaging with policymakers, industry professionals, and other stakeholders can also boost Altmetric scores. Sharing research findings with these groups increases the chances of mentions in policy documents or industry reports, which carry significant weight in Altmetrics. Similarly, presenting work at conferences and sharing related materials online can enhance visibility among peers and other attendees.
It’s also essential for researchers to optimize the discoverability of their work by ensuring accurate metadata, such as DOIs and ORCID IDs, and providing complete author information. This facilitates tracking by Altmetric tools and improves accessibility. Monitoring mentions and engagement through Altmetric platforms can help researchers identify where their work is being discussed and provide opportunities to participate in these conversations, further strengthening their online presence.
Importantly, researchers must avoid unethical practices, such as excessive self-promotion or using bots to inflate metrics artificially. By focusing on genuine engagement, responsible sharing, and effective communication, researchers can improve their Altmetric scores in ways that reflect the real impact and value of their work, ensuring credibility and integrity remain central to their efforts.
