I've spent 7 years in the trenches of paid media, running Meta Ads, Facebook Ads, Google Ads, TikTok, and Snapchat campaigns for brands across the US, Europe, Australia, the Middle East, and beyond. From tiny local businesses to fast-growing international brands, I've worked with clients in 15+ countries across wildly different markets and industries. I've managed budgets from $500 to $150,000/month, across 30+ niches, and honestly, I love the variety. Every business is a new puzzle to solve. 🧩 My work sits at the intersection of Performance Marketing and real strategy. I don't just run ads, I build systems that actually hold when you scale. Full-funnel Meta Ads, Facebook Ads, and Google Ads structures, proper Meta Pixel and Conversion API (CAPI) tracking, creative testing frameworks, audience segmentation, everything working together, not just ticking boxes. Whether you need a digital consulting session to figure out what's broken, or full campaign management across social media marketing and search, the process is the same: diagnose, fix, then scale. 💰 Recent results I'm proud of: 🔹 Scaled a London museum's Meta Ads revenue by 1,350%, lifting ROAS from 0.31 to 3.12 while completely restructuring their campaign setup 🔹 Took a US jewelry brand from ROAS 1.47 to 4.58 through controlled Facebook Ads, Meta, and Google Ads scaling, CAC dropped 30%, monthly spend grew to £17K profitably 🔹 Cut CPL by 57% and grew conversion rate by 297% for a US mental health clinic using audience segmentation and Google Ads restructuring 🔹 Generated 259% more leads for a solar energy company while reducing CPA by 60% through Meta Ads funnel optimization 🔹 Scaled a meal delivery brand to $98K/month in ad spend with 584 purchases/month, built from zero using TOFU/MOFU/BOFU Facebook Ads architecture 🔹 Grew Dubai limo bookings by 277% (116 → 437/month) without increasing CPA through Google Ads campaign restructuring and creative A/B testing ⚙️ How I work: I start by figuring out where the leaks are, tracking issues, wrong audience targeting, weak creative, broken funnel structure. Then I fix the foundation before scaling anything. 🔧 Whether it's Meta Ads, Facebook Ads, Google Ads restructuring, or building a creative testing system from scratch, I focus on what actually moves the numbers, not what looks good in a report. As a Media Buyer, I genuinely enjoy working closely with my clients. I ask questions, I dig into your business, and I care about the results as much as you do. 🤝 I'm a Performance Marketing specialist and Media Buyer who works well with eCommerce brands, lead gen businesses, startups, and scaling companies. My approach covers digital marketing across paid search and social media marketing channels, always built around data, testing, and sustainable growth. As a Media Buyer, I treat every advertising budget like it's my own. 📌 Platforms: Meta Ads, Facebook Ads, Google Ads (Search, Shopping, PMax), TikTok Ads, Snapchat Ads 📌 Tools: GA4, Looker Studio, Google Tag Manager, Shopify, Conversion API 📩 If your Facebook Ads or Google Ads campaigns are underperforming, unstable, or stuck, send me a message. I'll take a look at your setup and tell you exactly what's holding things back. Every Media Buyer has a different process, but my Performance Marketing approach is always focused on measurable business growth. No pressure, just an honest conversation. 😊 Anna S.
