Instagram

Instagram anchors 2.0 billion monthly active users as the premier visual platform, driving 500 million daily active users on Stories alone. Its Reels account for 40% of all time spent on the app, directly competing with TikTok's short-form video while maintaining a 15% higher average engagement rate per post than Facebook's rate at #1. This visual focus sets Instagram apart from Facebook's broad updates—users are 3x more likely to purchase after seeing a product in-feed. For influencers, average sponsorship rates of $1,000 per 100,000 followers outpace the industry median of $850.
