This study investigates the role of Facebook posts as online triggers for English as a Second Language (ESL) learner’ motivation and performance. The study explores the motivational dynamics of how Facebook language influences learning in the community by exploring the interconnectedness of emotional linguistic strategies. A mixed-methods approach was adopted to collect Facebook posts and open coding and thematic coding techniques were employed to analyze the data. The participants were administered pre- and post-tests to collect their performance outcomes for t-tests. The findings reveal that Facebook posts about learning English as a second language (L2) provide primary motivation for learners and promote their performance. These posts are triggers for their L2 understanding and enhance their language learning motivation and performance. Their affirmation and agreement, sharing of personal experiences and testimonials, reflection, seeking advice and guidance work as projectors in the motivational strategies of ESL learners. Furthermore, motivation is facilitated by the use of attractive Facebook posts. Additionally, practical implications highlight the importance of creating supportive and engaging language learning environments. Further research is recommended to explore motivational dynamics in different digital contexts and platforms.
