Social media platforms are essential for online scholarly activities in the time of the COVID-19 pandemic. Their use is critical in countries of non-mainstream science. This study aimed to evaluate the role of social media in scholarly activities in Eastern Europe. We collected responses from 127 scholars from Ukraine, Poland, Lithuania, and other Eastern European countries. They mainly reported spending 1–2 hours on social media activities. ResearchGate, Facebook, and LinkedIn were the most popular channels for post-publication article promotion. Only 17.3 % of respondents were familiar with metrics
generated by Altmetric.com and Plum Analytics. Increasing awareness of the role of social media platforms and metrics for scholarly purposes requires more attention in Eastern Europe.
