Impact of Tweeting Summaries by the Japanese Circulation Society Official Account on Article Viewership-Pilot Trial

Background: The impact of promotional tweets from the official journal account (for Circulation Journal and Circulation Reports) on article viewership has not been thoroughly evaluated. Methods and Results: We retrospectively collected journal viewership data for Circulation Journal and Circulation Reports from March 2021 to August 2021. We compared viewership between articles with (n=15) and without (n=250) tweets. After 1 : 4 propensity score matching (15 tweeted articles and 60 non-tweeted matched controls), journal viewership metrics within 7 days of the tweeting date (and the hypothetical tweeting date), was larger in tweeted articles than non-tweeted articles (median [interquartile range] Abstract page views 89 [60-104] vs. 18 [8-41]). Conclusions: This pilot study suggests a positive relationship between journal-posted promotional tweets and article viewership.
