What eStudio34 does
eStudio34 (legal name: CLAREMONT STUDIOS, S.L.) is a Barcelona-based digital marketing agency that has operated continuously since 2010. The company's service offering is organized under a 'Full Stack Marketing' methodology that combines four pillars: SEO (technical audits, link building, international SEO, content strategy), SEM and PPC (Google Ads, social media advertising, YouTube, Amazon), CRO (UX analysis and A/B testing), and Web Analytics (Google Analytics 4 configuration, tagging, and BigQuery integration). Supporting sub-products include ASO mobile marketing, multilingual SEM, content marketing, and platform-specific advertising management across Google, Meta, LinkedIn, Amazon, and Pinterest.
The agency's technology stack centers on the Google ecosystem (Google Ads, Google Analytics 4, YouTube, Google Shopping) complemented by major social and commerce advertising platforms. Data analysis capabilities leverage the native GA4-to-BigQuery integration for SQL-based analytics, used to forecast campaign performance and inform optimization decisions. The firm holds Google Premier Partner and Meta Business Partner certifications, and was nominated for the Google Partner Awards 2016 in the Mobile Performance category. Disclosed AI usage is limited to consumer-grade tools — ChatGPT for generating and optimizing Google Ads scripts and copy, and Google Performance Max for automated bidding — with no in-house AI model development evident.
Revenue is generated through professional services retainers and project-based engagements, with pricing quoted per client rather than published. Go-to-market is sales-led and direct, with dedicated SEM Account Managers and PPC Account Executives assigned to each client. The customer base spans ecommerce (Pierre & Vacances, Rituals, Xti, Raja, General Optica), education (Universitat de Barcelona, CUNEF), consumer goods (Campofrío), real estate (Engel & Völkers), publishing (Salvat), and startups (JobToday). Operations are headquartered in Spain with multilingual SEM services extended to Germany, France, Italy, Portugal, and the United States.
