TikTok: Her Powerhouse Platform for Humor and Relatability

‍

‍

Dudinha's TikTok strategy revolves around quick, engaging, and humorous videos that highlight both her playful personality and her connection with animals. She posts consistently—13 videos per week—often using regional expressions and quirky editing styles that resonate with Brazilian Gen Z viewers. Her animal-centric content, whether it’s her reacting to pets or showcasing a funny situation, blends lifestyle and comedy seamlessly. With over 13.7M followers, she has clearly mastered short-form storytelling that feels spontaneous yet culturally grounded.

‍

Her humor is distinctly local, which gives her a strong foothold in Brazil’s creator landscape. She frequently uses text overlays and facial reactions to amplify her comedic timing, a method that works exceptionally well for reaction-style videos. Dudinha doesn't just follow trends—she adapts them to her own niche, often incorporating animals and unexpected daily-life moments to keep her audience engaged. This adaptability has led to consistently viral content with six-figure engagements.

‍

‍

Unlike creators who post sporadically, Dudinha has built trust with her audience through frequency and predictability. She posts twice daily at 4 PM, maximizing her reach among early risers and school-age followers. The timing helps her stay top-of-mind in the algorithm, particularly on days when user engagement spikes. It also suggests that her content is pre-scheduled or well-planned—indicating a mature, strategic approach despite her youthful tone.

‍

Her TikTok performance stands out not only in scale but also in cross-platform virality. Videos often receive hundreds of thousands of likes and are easily shareable due to their casual, funny, and emotionally resonant nature. Her engagement rate might not be high in percentage terms (0.09%), but in raw numbers, she regularly pulls over 100K likes per post. Her ability to remain culturally attuned and lighthearted makes TikTok her strongest channel by far.

Instagram: Daily Intimacy with a Visual Storytelling Edge

‍

‍

Dudinha's Instagram strategy leans into daily storytelling—balancing lifestyle, veterinary moments, and animal rescue stories. With 2 million followers and a score of 90.8/100, she posts nearly every day, usually around 4 PM, maintaining a routine that keeps her visible in Brazil’s early scrolls. Her use of carousels, reels, and raw images makes her feed feel both authentic and curated. Instagram offers a more personal look into her daily life compared to the high-energy TikTok posts.

‍

Her Reels showcase everything from pet grooming to funny moments with monkeys or goats, often amassing hundreds of thousands of views. She leverages her veterinary background by subtly adding informative, compassionate elements to these posts—without losing humor or relatability. Posts are often captioned in informal Portuguese, reinforcing intimacy and regional identity. It's this balance of charm and consistency that helps her maintain high average engagement numbers (17.6K).

‍

‍

Visuals play a significant role in her Instagram growth. Unlike creators who overly edit, Dudinha’s content feels immediate and real—like something you’d see on a friend’s story rather than a celebrity’s feed. From holding a horse hoof to caring for rescued animals, she turns routine moments into meaningful, visual narratives. This builds trust and keeps followers emotionally invested in her journey, even outside viral moments.

‍

Her content style on Instagram also aligns with brand collaboration strategies. With partnerships like SHEIN Brasil and Glowmode Official, she smoothly integrates sponsored content in a way that still feels personal. Her animal-driven lifestyle pairs well with activewear, pet brands, and youth-targeted fashion. It’s no surprise her content is rated as highly safe and bright, with a strong lean toward visual positivity.

YouTube: A Dormant Yet Potentially Rich Channel

‍

‍

Dudinha’s YouTube presence, under the handle @dudinhaaarruda4338, shows signs of being a secondary or legacy platform rather than a current growth engine. With 187K followers but 0% activity in the last four months, this channel appears inactive or deprioritized. Her influence score here (19.9/100) is notably lower than on her other platforms, indicating minimal recent performance. It’s likely she’s choosing to focus energy on higher-ROI platforms like TikTok and Instagram.

‍

Despite the inactivity, YouTube still holds potential. Given her large following and loyal fan base, long-form content could allow her to explore deeper narratives—perhaps behind-the-scenes footage of her veterinary journey or more detailed animal rescues. If she reactivates this platform, she could easily cross-promote it through her thriving TikTok and Instagram audiences. There’s clear room for storytelling expansion if she wants to evolve her brand.
