Search behavior has evolved rapidly. Users now search through Google, ask questions via voice assistants, and rely on AI-generated answers. This shift has given rise to three critical optimization strategies: SEO, AEO, and GEO.
Understanding the difference is essential for businesses that want to stay visible in 2025 and beyond.
