Introduction: The AI Search Revolution
The launch of ChatGPT in November 2022 marked a turning point in how people search for information. For the first time, users could ask complex questions and receive comprehensive, conversational answers instead of a list of links. This shift has profound implications for SEO and digital marketing.
AI-powered search is not replacing traditional search—it's creating a parallel discovery channel that businesses must optimise for. With ChatGPT reaching 100 million users faster than any application in history, and Google integrating AI Overviews into search results, the landscape has fundamentally changed.
"By 2026, traditional search engine volume will drop by 25% as users embrace AI chatbots and virtual agents." — Gartner
This comprehensive guide explores how ChatGPT and other Large Language Models (LLMs) are impacting SEO, and what you need to do to ensure your business remains visible in this new era.
