SEO in 2025 is being reshaped by AI, answer engines, and changing user behavior. Traditional keyword strategies are giving way to entity-based optimization, conversational queries, and Generative Engine Optimization (GEO) for AI-driven results like Google’s AI Overviews. Zero-click searches and AI visibility are now key performance metrics, while E-E-A-T remains critical for building trust. To succeed, brands must structure content for AI consumption, balance entities with keywords, and focus on authority, speed, and accessibility. In short, SEO in 2025 is not just about rankings, it is about recognition and visibility in an AI-first search landscape.
