Search behavior continues to evolve as users shift toward AI-driven answers. Instead of browsing long lists of blue links, people increasingly rely on systems such as ChatGPT, Gemini, and Perplexity to summarize information instantly. Brands now need visibility inside these generated responses, which has created a new category of optimization focused on AI SEO and large language model (LLM) visibility.
The agencies below are helping companies adapt to this major change. Their work centers on improving entity recognition, strengthening authority signals, and building content structures that AI systems use to form answers.
