The evolution of SEO traces back to the birth of the internet and the emergence of search engines in the 1990s. From Archie and Yahoo to the game-changing launch of Google in 1998, SEO underwent significant transformations. Initially, SEO revolved around keyword stuffing and meta tag optimization. However, the landscape shifted with Google's algorithm updates like Panda and Penguin, which penalized manipulative tactics and prioritized high-quality content. The rise of mobile internet further altered SEO strategies, emphasizing mobile-friendly websites and local SEO. AI advancements, such as RankBrain and BERT, revolutionized SEO by understanding user intent better. E-A-T (Expertise, Authoritativeness, Trustworthiness) became crucial, especially for sensitive content areas. Voice search and zero-click searches emerged as new challenges, requiring tailored optimization approaches. As SEO continues to adapt to technological shifts and user behaviors, staying updated with the latest trends remains essential for digital success.
