A business researcher is conducting a study to investigate how social media engagement impacts the financial performance of small and medium$-$sized enterprises $($SMEs$)$ in the Johannesburg Metropolitan Municipality $($JMM$).$ The study also aims to determine whether the effect of social media engagement differs between SMEs in the manufacturing and service sectors$.$ The objective is to provide actionable insights for optimising social media strategies to improve financial outcomes for SMEs across these sectors within the JMM$.$ Understanding these dynamics can assist SMEs in tailoring their social media efforts to enhance financial performance and gain a competitive advantage.

To measure social media engagement, the researcher used the Social Media Metrics Questionnaire $($SMMQ$)$ framework developed by Oeldorf$-$Hirsch, Sundar, and Liang $(2023).$ The social media engagement rate $(\%)$ was calculated as the total number of likes, comments, shares, and clicks divided by the number of followers, expressed as a percentage. Financial performance was evaluated using firm annual revenue growth $($FRG$)(\%),$ which tracks revenue changes attributable to social media efforts $($Kumar et al$.,2024).$
