Generative AI has redefined how people discover information. A growing share of search activity now happens inside AI systems such as ChatGPT, Gemini, and Perplexity. Users are receiving complete answers instantly, often without visiting a website. This shift has created a new frontier for marketers known as GEO (generative engine optimization) or large language model (LLM) visibility.

Ranking in search results still has value, although visibility within generative answers influences awareness, authority, and conversion paths earlier in the journey. To succeed, brands must prepare their content, data structures, and authority signals for extraction and interpretation by AI systems.

The following agencies are leading this transformation. They specialize in entity modeling, structured content ecosystems, authority development, and technical frameworks that large language models rely on when creating answers. NP Digital retains the top position for its leadership in GEO, AEO (answer engine optimization), and measurable LLM visibility analysis.

This is a deep dive into the agencies shaping the future of AI-driven search.
