Sandra L.'s Social Media Strategy Analysis
LinkedIn Strategy: Building Cybersecurity Careers Through Practical Mentorship

Sandra uses LinkedIn to empower aspiring cybersecurity professionals with real-world advice, technical resources, and hands-on learning opportunities. Her posts focus on free labs, SOC certification guides, and career entry strategies. Each post is structured for clarity, offering immediate value to beginners navigating a complex field. The tone is practical, welcoming, and always rooted in her own experience.
She shares twice a week at midnight, a time likely intended to capture early international and late-night scrollers in tech. Her content is often image-supported—showing her in learning environments, events, or using tech—building authenticity and trust. Posts regularly surpass 2K likes and hundreds of comments, showing strong engagement from both learners and professionals. Her average post reaches nearly 56K viewers.

Sandra’s influence here is driven by consistency and credibility. Her top-performing posts often feature lists of curated learning resources or personal reflections on industry growth. With 183.8K followers and a 0.42% engagement rate, she proves that even with modest activity (8 posts/month), clear, useful insights can drive community growth. She balances algorithm-aware posting with audience-first content.
This platform allows her to showcase authority while remaining relatable. Her background as a self-taught or community-driven expert appeals strongly to LinkedIn users transitioning into tech careers. As a result, she has become a sought-after voice not just for job seekers, but also for organizations looking to support workforce development in cybersecurity.

YouTube Strategy: Visualizing Learning Paths for Beginners in Cybersecurity

Sandra’s YouTube channel, With Sandra, is her most content-rich platform, focusing on visually guided education for infosec newcomers. She presents full-length tutorials, salary breakdowns, and overviews of free course platforms like TryHackMe. Her delivery style is calm, confident, and simplified—making even technical topics digestible. With 145K subscribers, her audience trusts her to break down what others overcomplicate.
Each month, she uploads around four videos, primarily around 8PM, aligning with YouTube’s discovery algorithm patterns. Her content is a mix of traditional long-form videos and vertical shorts that repurpose or preview longer content. Her most watched videos often compare certifications or summarize “Top 5” free cybersecurity courses—titles that align with searchable beginner concerns. On average, she generates 8.4K views per video.

Sandra’s visual branding remains consistent: clean thumbnails, centered framing, and minimal distractions help maintain viewer focus. Her tone is always respectful of her audience’s learning curve—she explains concepts like threat actors or SOC roles without jargon. Even as she scales, she avoids chasing trends or shifting tone. Instead, she strengthens her identity as a trusted guide.
This channel is especially important in building her long-term influence. While other platforms drive visibility, YouTube anchors Sandra’s brand in educational value. It also allows for deeper integrations with partner tools and training platforms, helping her promote free resources in a way that feels organic and helpful rather than promotional.

Instagram Strategy: Capturing Micro-Moments of Learning and Community Building

On Instagram, Sandra publishes fast-paced, highly digestible cybersecurity reels that feel both casual and instructive. She uses caption overlays and quick hooks to catch attention—such as “Microsoft is giving away 50,000 free certifications!”—making technical content instantly shareable. Her posts often feature her in professional settings, reinforcing credibility while maintaining visual appeal.
She posts around 13 times a month, with her most active slot being 10AM—ideal for engaging younger tech learners browsing after hours. Reels outperform standard posts, with top clips like her phishing reel hitting over 164K views and 11.5K likes. Her use of call-to-actions—“Comment ‘Start’ to get a link”—has boosted engagement and built a recurring DM-based lead system.

Sandra’s visual approach is strategic yet approachable. She uses on-screen text to reinforce concepts and ensure accessibility even when viewed without sound. Her average engagement rate of 2.5% outpaces her other platforms, signaling a loyal community of early-stage learners. These followers rely on her for tips they can act on immediately, such as certification vouchers or tool recommendations.
Instagram allows her to communicate quickly and repetitively, which is ideal for reinforcing evergreen learning concepts. While LinkedIn builds professional trust and YouTube delivers deep dives, Instagram captures impulse learners—people casually exploring tech. Sandra leverages that window by offering bite-sized advice that turns curiosity into action, making it her most conversion-efficient platform.
