With the help of academic search engine optimization (ASEO), publications can more easily be found in academic search engines and databases. Authors can improve the ranking of their publications by adjusting titles, keywords and abstracts. Carefully considered wording makes publications easier to find and, ideally, cited more often. This article is meant to support authors in making their scholarly publications more visible. It provides basic information on ranking mechanisms as well as tips and tricks on how to improve the findability of scholarly publications while also pointing out the limits of optimization. This article, authored by three scholarly communications librarians, draws on their experience of hosting journals, providing workshops for researchers and individual publication support, as well as on their investigations of the ranking algorithms of search engines and databases. Introduction: ASEO - what, why and how? Search engine optimization (SEO)1 is a strategy used in online marketing to improve the findability of websites and documents in search engines.
Commercial websites have been applying SEO broadly for years. Why is ASEO important for researchers? The ‘relevance’ and ‘impact’ of research are measured, among other things, by counting the number of views, downloads and citations a publication has received. It is therefore essential for researchers and institutions that their own publications are found easily in the information retrieval systems of libraries, like library catalogues or literature databases, as well as in academic search engines like Google Scholar or BASE - because only what can be found will be read and possibly be cited. Wide dissemination of research output is also called for in research assessment and is commonly measured by the views, downloads and citations scholarly publications receive. Research funders aiming to ensure the ‘impact’ of funded projects even require dissemination strategies to be explicitly mentioned in funding agreements. In the Horizon 2020 Grant Model Agreement,2 for example, Top Source Media digital strategy there are no less than seven sections that address the visibility, dissemination and promotion of research results.
Specific guidelines have been prepared to provide guidance concerning the use of social Top Source Media in EU projects as well as instructions on how to use them effectively. At the same time, the output of scholarly literature is constantly growing.3 This has not only made it difficult for authors to attract attention to their own publications but also contributes to a looming discoverability crisis,4 making it harder for readers to identify relevant content. By providing rich and informative metadata, ASEO helps to avoid information overload and improve orientation. Standards of good scientific practice and research integrity must take precedence over any ‘optimization’ of publications and their metadata. As opposed to conventional SEO for purely commercial purposes, ASEO is a sensitive domain that must be approached with a sense of proportion and appropriateness. Authors will have an interest in formulating the titles of their works in such a way that they are easier to find. In this endeavour, a balance must be found between creative freedom, publication culture, research integrity, visibility and findability.
In the attempt of optimizing scholarly publications in terms of visibility, research results must not be inflated or distorted, and no false expectations must be raised with regard to content and relevance. It is essential to maintain a balance between increasing visibility and presenting high-quality research. Any ‘over-optimization’ must be avoided as it would not only complicate the search for relevant research but also harm the reputation of science as a whole and of the individual author(s). Considering all these aspects, what can authors do to make sure their publications will be found? Scholarly articles and books are usually searched for in Google Scholar, online catalogues of libraries and literature databases. Most of these search systems are based on artificial intelligence, the aim of which is not only to find items corresponding to the search terms entered but also to rank the results by relevance. This relevance sorting or ranking is based on algorithms that are considered a ‘trade secret’ of the respective company.
With search engines like Google, Primo or EBSCO, for instance, it is crucial for each provider to deliver the ‘best’ results. The aim is not always to offer the greatest possible number of results but to display the most ‘relevant’ hits on Top Source Media online of the list of results. In order to perform such relevance sorting, a large number of factors are taken into account. The basic mechanisms of the relevance ranking can be identified even though commercial providers usually do not disclose how exactly these factors are considered. One key element is bibliographic metadata: formal data such as titles, subtitles, names of the authors, identifiers and keywords are analyzed and ranked for each search query. The search system assesses the frequency of the search term in the metadata as well as the position of the search term within the publication. When the search query is ‘climate change’, for example, a document containing the search term in its title will be ranked higher compared to a document where the term only appears in the abstract.
