Ana Kostic

Ana Kostic has been inside Google Ads and Meta accounts since 2009, long enough to stop trusting the default dashboard and start asking what a number actually cost the business. She is Co-founder and Head of Paid Media at bigmomo, a performance marketing agency based in Spain, where she still runs live accounts and leads the PPC team.

Her deepest experience is in lead generation and B2B in international campaigns. Day to day she works Search, Shopping, Performance Max and lead generation across multiple markets and languages. She writes from the operational side of paid media: account structure, budget pacing, reporting and whether the CRM agrees with what the Ad Platform is celebrating.
