Adolescents and young children (roughly ages 10-19) are the most affected by social media due to crucial brain development, heightened peer sensitivity, and identity formation, making them vulnerable to mental health impacts like anxiety, depression, and low self-esteem from comparisons, bullying, and unrealistic ideals, with girls aged 11-13 and boys 14-15 showing specific vulnerability.
According to a survey of U.S. adults conducted by the Pew Research Center, the 18-to-29 age group is the most prominent on social media, most actively using YouTube (93 percent), Instagram (76 percent), Facebook (68 percent), Snapchat (65 percent) and TikTok (59 percent).
The 30-30-30 rule for social media is a content strategy dividing posts into three equal parts: 30% about your brand (promotions, behind-the-scenes), 30% featuring others (curated content, UGC, partners), and 30% for fun/engagement (memes, polls, educational content), with a potential extra 10% for spontaneous, real-time interactions. It emphasizes balancing promotional posts with building community and providing value, ensuring your brand feels human and connected rather than overly salesy.

The 5-5-5 rule in social media has a few variations, most commonly focusing on engagement (like 5 posts, comment on 5, within 5 minutes) for building relationships, or a content strategy (5 curated, 5 original, 5 promotional posts) to balance value and sales, ensuring your audience gets diverse content without being overwhelmed by ads, say this LinkedIn article and this article from Prontosys.ae.
