Enterprise search is entering a new era.
For years, brands focused on improving visibility through traditional SEO strategies designed to increase rankings on Google and Bing. Today, however, decision-makers are increasingly using ChatGPT, Gemini, Claude, Perplexity, Copilot, and Google’s AI Overviews to research vendors, evaluate solutions, and compare products.
As AI-powered search platforms become a larger part of the buying journey, enterprise organizations are looking for new ways to ensure their brands remain visible where customers are searching.
This has fueled the rise of AI search optimization, a discipline focused on helping brands appear in AI-generated answers, recommendations, citations, and summaries. The best agencies combine technical SEO, entity optimization, content strategy, digital PR, structured data, and analytics to improve how AI systems discover and reference information.
