A social media challenge is a popular interactive trend where users are encouraged to create and share content based on a specific prompt, theme, or action. These challenges often involve performing a particular dance, attempting a food-related feat, or showcasing a skill, and are typically amplified through a unique hashtag. Challenges drive significant user participation and virality, making them a powerful tool for brands and creators to increase engagement, reach, and community building on platforms like TikTok and Instagram.
