TikTok: Short-Form Content and Beauty Insights

On TikTok (@osulliliv), Olivia Sullivan-Davis engages her 55.5K followers with a mix of beauty tutorials, fashion trends, and relatable lifestyle content. Although her TikTok audience is smaller than her Instagram following, the platform allows her to showcase a more spontaneous and unfiltered side of her personality. Her TikTok content is casual and real-time, offering a contrast to her curated Instagram feed. This platform serves as a secondary yet valuable channel for her audience to connect with her in a more authentic and interactive way.

Despite her lower engagement rate of 0.11%, her best-performing videos often feature beauty tips, product reviews, and fashion hauls. These videos align with her audience’s interests, reinforcing her authority in beauty and style content. Olivia maintains a posting schedule of approximately 2.5 videos per month, keeping her content fresh but less frequent compared to her Instagram presence. The spontaneity of TikTok videos allows her to experiment with more personal and humorous content, adding to her relatability.

However, her growth on TikTok has remained stagnant in the past 30 days, signaling an opportunity to revamp her strategy. A higher posting frequency and participation in trending challenges could help increase her visibility on the platform. Olivia could leverage TikTok’s algorithm by incorporating popular sounds, engaging duets, and interactive storytelling to attract a wider audience. By doing so, she could boost engagement and increase her follower count significantly.

To maximize her potential on TikTok, Olivia may benefit from diversifying her content with viral trends, collaborations, and interactive Q&A sessions. Given the platform’s focus on engagement and discoverability, a more dynamic content plan could position her as a stronger presence in the fashion and beauty niche. If she amplifies her efforts, TikTok could become a key growth platform for her personal brand.
