Nils Fehr

Self Employed Performance Marketer

Dec 2019 - Present • 6 yrs 9 mos

I run paid acquisition for e-commerce, app and B2B service brands under my own brand, AdSynergy - around $2.5M in annual ad spend, 500+ clients worldwide, Fiverr Top Rated for social ads. Google Ads: Search, Shopping, Performance Max and AI Max - account structure, keyword research, RSA copy, negative-keyword strategy, bidding and ongoing optimization. Meta & TikTok Ads: full-funnel lead generation and iOS app-install campaigns, ICP/persona screening tests and structured creative testing. Microsoft Ads, Reddit Ads and OpenAI/ChatGPT Ads, usually mirroring the Google setup 1:1. Tracking is part of the job, not an add-on: Google Tag Manager (web and server-side), GA4, conversion actions, Meta Pixel + Conversions API, Microsoft UET, consent mode and CMP integration - clean attribution before anyone scales spend. I also build what the traffic lands on: Shopify stores, Next.js/TypeScript/Tailwind sites, lead-gen landing pages, Klaviyo email flows and CRO iterations. Sectors: telemedicine and pharmacy, professional services, driving schools and vocational training, solar, roofing and electrical trades, meditation and wellness apps, pet and consumer e-commerce. How I work: read-only audit first, changes only after your approval, documented before/after on every edit, no blind auto-apply, and reporting you can actually read.

Freelance Web Developer & Tracking Specialist

Dec 2019 - Present • 6 yrs 9 mos

Websites, shops and landing pages built to convert - usually for traffic I buy myself, which changes how they get built. Shopify: complete store builds, theme and Liquid customization, app integrations (Klaviyo, digital product delivery, pre-order and checkout flows) and data-driven CRO iterations. Custom development: Next.js, TypeScript and Tailwind CSS - fast, SEO-clean company sites and landing pages, deployed and maintained end to end. Paid-traffic landing pages: hero lead forms, UTM and GCLID capture written into every lead, honeypot spam protection, session-safe conversion firing and a structure that is ready for A/B testing. Measurement: GTM web and server-side containers, GA4, Google, Meta, TikTok, Microsoft and Reddit conversion tracking, consent mode and CMP gating - implemented and verified, not just pasted in. Automation: Klaviyo email flows plus CRM and form connections (HubSpot, Typeform, Calendly). Recent builds include e-commerce stores, a pharmaceutical company site, local service websites and lead-gen landing pages for the German market.
