TikTok Strategy: Comedic Rants and Daily Snapshots

Mariona’s TikTok is her creative core, where she shares day-to-day scenarios with a humorous twist. Her dual identity as a nurse and performer allows her to tell stories few creators can. She often uses character-based skits to illustrate awkward, funny, or emotional moments from the hospital setting. These sketches are highly relatable to a young Spanish-speaking audience.

She posts around 2.7 videos/week, maintaining a consistent publishing schedule at 2 PM EST three times per week. Despite not gaining new followers in the past 30 days, her videos still average 128.3K views, showing continued interest. Her best-performing content often includes reenactments of real conversations with patients or coworkers. This focus on authenticity keeps her visibility high despite stagnant growth.

Mariona’s engagement rate on TikTok is 0.42%, with an average of 7.6K engagements per video, slightly below viral standards but strong for niche storytelling. Her followers interact more with her personality-driven posts than with trend-based content. She avoids overly produced videos and instead uses her acting skills to drive natural viewer retention.

She has been tagged 7 times by MediaMarkt España, integrating their products into her videos without interrupting her style.

Her comments are filled with fans referring to previous skits or personal stories she’s shared, showing memory-based interaction. She tags brands like Wallapop and Samsung España directly in posts that feel like product recommendations, not ads. This style resonates because it respects her audience’s time and trust in her judgment.

Most branded content on Instagram includes styled photography featuring products Mariona uses or wears in everyday life.

Her use of natural light and expressive posing aligns with the platform’s visual trends while staying grounded in her tone. This mix of realness and aesthetic makes her posts effective for product placement.

YouTube Strategy: Inactive but Reserved for Future Potential

Mariona’s YouTube channel, La Merions, is inactive with no uploads in the last year, and only 2.1K subscribers. It currently serves more as a placeholder than a content destination. Her score on the platform sits at just 6.8/100, reflecting the lack of recent activity or engagement. This makes YouTube her least developed social media channel.

There are 0 videos/month and 0 engagement, which signals that she may be prioritizing short-form video over long-form content. Her style—quick storytelling, character-driven humor—translates well on TikTok but hasn’t yet been adapted for YouTube. If she were to launch a series around her theater studies or patient interactions, she could attract an entirely new audience.
