  Social media platforms have now emerged as an important medium for wider
dissemination of research articles; with authors, readers and publishers
creating different kinds of social media activity about the article. Some
research studies have even shown that articles that get more social media
attention may get higher visibility and citations. These factors are now
persuading journal publishers to integrate social media plugins in their
webpages to facilitate sharing and dissemination of articles in social media
platforms. Many past studies have analyzed several factors (like journal impact
factor, open access, collaboration etc.) that may impact social media attention
of scholarly articles. However, there are no studies to analyze whether the
presence of social media plugin in a journal could result in higher social
media attention of articles published in the journal. This paper aims to bridge
this gap in knowledge by analyzing a sufficiently large-sized sample of 99,749
articles from 100 different journals. Results obtained show that journals that
have social media plugins integrated in their webpages get significantly higher
social media mentions and shares for their articles as compared to journals
that do not provide such plugins. Authors and readers visiting journal webpages
appear to be a major contributor to social media activity around articles
published in such journals. The results suggest that publishing houses should
actively provide social media plugin integration in their journal webpages to
increase social media visibility (altmetric impact) of their articles.
