Promotion of Scientific Publications on ArXiv and X Is on the Rise and Impacts Citations

In the evolving landscape of scientific publishing, it is important to understand the drivers of high-impact research, to equip scientists with actionable strategies to enhance the reach of their work, and to understand trends in the use modern scientific publishing tools to inform their further development. Here, based on a large dataset of computer science publications, we study trends in the use of early preprint publications and revisions on ArXiv and the use of X (formerly Twitter) for promotion of such papers in the last 10 years. We find that early submission to ArXiv and promotion on X have soared in recent years. Estimating the effect that the use of each of these modern affordances has on the number of citations of scientific publications, we find that in the first 5 years from an initial publication peer-reviewed conference papers submitted early to ArXiv gain on average $21.1 \pm 17.4$ more citations, revised on ArXiv gain $18.4 \pm 17.6$ more citations, and promoted on X gain $44.4 \pm 8$ more citations. Our results show that promoting one's work on ArXiv or X has a large impact on the number of citations, as well as the number of influential citations computed by Semantic Scholar, and thereby on the career of researchers. We discuss the far-reaching implications of these findings for future scientific publishing systems and measures of scientific impact.
