Instagram: A Balance of Fashion and Personal Insights

YouTube: A Platform with Untapped Potential

Katelyn’s YouTube channel, with 26.2K subscribers, is currently underutilized compared to her other platforms. She has posted infrequently, limiting her ability to engage viewers consistently. However, YouTube presents an opportunity for long-form content, including vlogs, styling tutorials, and fitness videos. With the right strategy, she could establish a strong presence and expand her audience further.
Her current YouTube growth rate is 0%, with no new followers added in the past 30 days. This stagnation is due to a lack of recent uploads, leading to 0% engagement. Despite this, YouTube remains a valuable tool for deeper audience connection. By increasing her activity, she could see significant improvement in views and engagement.

Katelyn’s last YouTube activity was 24 days ago, with an average posting rate of 0.2 posts per month. Many influencers use YouTube to provide extended content that complements their TikTok and Instagram presence. By repurposing existing TikTok videos into longer formats, she could capitalize on this opportunity. A more structured posting plan could help her build a strong YouTube audience.
Her current posting schedule is once a year at 7 PM EST, which limits her visibility on the platform. If she starts uploading consistently, she could create a space for in-depth fashion and wellness content. With her growing influence on other platforms, YouTube could be the next big step for her brand. Expanding into long-form content would allow her to engage with her audience on a deeper level.
