A playbook for effective age advocacy on Twitter.

BACKGROUND: Central to raising awareness of ageism are advocacy organizations dedicated to serving the needs and interests of older adults. Although many of these organizations have cultivated an online presence, inquiry into the effectiveness of age advocacy work on social media remains an untapped area. Our foray into this topic explores how different tweet features predict the level of engagement of posts uploaded by age advocacy organizations on Twitter. METHODS: Tweets (N = 403,426) were collected from 53 accounts and spanned 12 years from July 2009 to October 2021. After applying our exclusion criteria, 204,905 tweets were retained for analysis. We analyzed the tweet features (predictors) and engagement level (outcome variable) using a linear mixed-effects model. RESULTS: Tweets with higher engagement are those with a URL, with at least three hashtags, with visuals (GIF, photo, or video), which are quote tweets, and which are posted in the evening or at night Central Standard Time (CST), adjusting for account-level variables (e.g., follower count). Conversely, tweets with more than one mention, which are replies and which are uploaded in the morning are associated with lower engagement. CONCLUSION: The rise of digital media means that advocates have the opportunity to communicate their messages to reach a critical mass. This is the first known study to offer an evidence-informed playbook for age advocacy organizations to optimize outreach efforts by maximizing online engagement. These results represent a crucial step in ongoing efforts to tackle ageism, an issue that has long been under-discussed.
