The Advert Elixir

The Advert Elixir is a specialist digital marketing consultancy founded by Katrina M McBride, based in Donegal, Ireland. The company works with clients across Ireland, the United Kingdom, the United States, Australia, and Canada, delivering full-service digital marketing strategy and execution entirely remotely.

The consultancy specialises in Meta ads management, paid social advertising, lead generation funnel building, and AI-powered marketing automation for SMEs and growing businesses that need fast, measurable results. Unlike large agencies that delegate client work to junior teams, The Advert Elixir operates with a deliberately small client roster, ensuring Katrina M McBride remains directly involved in strategy and execution on every account. With over 12 years of hands-on experience managing Meta advertising campaigns across multiple industries and markets, the team has a proven track record of delivering significant commercial outcomes. Highlights include scaling a business from €1 million to over €10 million in annual revenue through Meta advertising strategy, achieving a 6.3x return on ad spend for e-commerce clients, and generating a 200% increase in qualified leads for service businesses.

Katrina M McBride holds a Masters degree in Marketing and Google Ads certification. Industries served include legal and law firms, skincare and beauty brands, hair product companies, medical and healthcare practices, retail businesses, and professional services. The Advert Elixir's proprietary Growth Elixir AI system combines paid advertising strategy, AI automation, and conversion optimisation into one joined-up growth engine tailored to each client's specific business goals and market. The consultancy offers two engagement models: Done-For-You digital marketing management, covering full strategy and execution, and Meta Ads Advisory and Training for businesses building internal marketing capability.
