Generative Engine Optimization (GEO) is the new frontier in digital marketing. This discipline focuses on optimizing your brand’s presence to be recommended by generative AI platforms like Google Gemini, ChatGPT, and Perplexity. A successful GEO strategy integrates SEO, content development, public relations, and technical optimization to build authority and trustworthiness. With the global market for AI-driven SEO services projected to hit $4.5 billion by 2026 [1], choosing the right partner is critical.

- Notable Clients (35%): The agency’s track record with significant clients, prioritizing demonstrated GEO results over general marketing case studies.
