About Barbara Zumiko

I am aGrowth & Performance Strategistspecializing in improving the conversion and profitability of digital businesses.

I work with companies that are already investing in marketing but are not getting the expected results.

My approach is not to increase the budget, but to optimize what already exists: campaigns, funnels, measurement, and user experience.

I have led projects where advertising spending has been reduced by up to 50% while maintaining revenue, rebuilding measurement from scratch (GA4, GTM, dashboards), and identifying critical friction points in the purchase process.

My experience combines:
  • Google Ads and Meta Ads (strategy and optimization).
  • CRO and funnel analysis.
  • Measurement implementation and auditing (GA4, Tag Manager).
  • Technical SEO and content architecture.
  • Audits focused on SEO, GEO (Generative Engine Optimization), and search experience.

Currently, I am focused on helping businesses adapt to the new changes in the digital ecosystem, where visibility depends not only on traditional SEO but also on how search engines and AI interpret and prioritize content.

I work closely with my clients, explaining each step and making data-driven decisions, not intuition-based ones.
