The Innovation of Google Search: From Keywords to AI-Powered Answers
Launching in its 1998 inception, Google Search has advanced from a primitive keyword processor into a responsive, AI-driven answer tool. At the outset, Google’s game-changer was PageRank, which ordered pages by means of the worth and magnitude of inbound links.

This minimizes the need to click diverse links to assemble an understanding, while but still orienting users to more detailed resources when they desire to explore.
For users, this journey represents quicker, more specific answers. For professionals and businesses, it values profundity, novelty, and transparency above shortcuts. Moving forward, foresee search to become expanding multimodal—frictionlessly unifying text, images, and video—and more user-specific, tuning to configurations and tasks. The transition from keywords to AI-powered answers is at its core about changing search from detecting pages to achieving goals.
