The Complete History of Search Engines
Key Takeaways – History of Search Engines
The history of search engines began in 1990 with Archie and evolved through stages—manual directories (Yahoo!), crawler-based indexing (Lycos, AltaVista), and link-based ranking (Google). The 2000s introduced personalization, real-time search, and mobile-first indexing. More recently, AI-driven models like BERT and MUM transformed how search engines understand queries and serve results.
