As analyses of the year-to-year index-level performance of the Open Access journals of De Gruyter indicate, narrow-scope Open Access journals have tended to outperform their more recently launched, broad-scope counterparts.

CiteScore is a metric developed by Elsevier, to reflect the citation impact of individual academic journals. This metric, thus, assesses the average number of citations that journal articles receive over the preceding three years based on the information from the Scopus database.
Based on the international journal metrics of Scopus, in recent years the Open Access portfolio of De Gruyter comprising indexed journals has grown significantly, while increasing its average CiteScore performance. Open Access journals have demonstrated an average CiteScore of 0.516 in 2014. Moreover, in 2014 the maximum CiteScore Open Access journals have attained was 2.03. Additionally, in terms of the highest CiteScore, in 2015 Open Access journals have improved their performance to 2.13.
Excluding trade journal data, in 2016 the average CiteScore performance of Open Access journals stood at 0.632. This figure is higher than its 2014 and 2015 counterparts for Open Access titles. Similarly, in 2017 the average CiteScore performance of Open Access journals has increased to the level of 0.765. Additionally, in 2017, the best performing Open Access journal has reached the CiteScore of 5. This result is significantly higher than the maximum CiteScore level for their 2016 counterparts of Open Access titles.
Likewise, in 2018 the average CiteScore performance of Open Access stood at 1.035. Furthermore, between 2014 and 2018 the Open Access journal portfolio of De Gruyter has almost doubled its average CiteScore levels. Similarly, the average CiteScore has also been rising continuously between 2015 and 2018.
In particular, across this period, narrow-scope, specialized journals, such as Biomolecular Concepts which had a CiteScore of 3.35 in 2018, have tended to demonstrate better CiteScore performance than their broad-scope counterparts, e.g., Open Chemistry with a CiteScore of 1.58 in the same year.
Similarly, in 2018 journals in the fields of applied sciences chemistry, engineering, geosciences, e.g., Noise Mapping with a CiteScore of 3.18, have had significantly higher citation impact performance than titles in humanities and social sciences, e.g., Open Linguistics with a CiteScore of 0.7.
