The history of Search Engine Optimization (SEO) is closely tied to the evolution of search engines and the changing landscape of the internet. SEO has grown from a niche marketing strategy to a fundamental aspect of online visibility and digital marketing. Here’s a brief overview of the history of SEO:

1. 1990s – The Birth of Search Engines:

   • These updates emphasized the importance of high-quality, user-focused content and ethical SEO practices.

   • AI and machine learning play a significant role in search algorithms, with Google’s BERT (Bidirectional Encoder Representations from Transformers) update in 2019 enhancing the understanding of natural language.

8. 2020s – User Experience and Technical SEO:

   • Google’s emphasis on Core Web Vitals in 2021 underscores the importance of user experience metrics, including page speed, interactivity, and visual stability.
