What is SEO?
A Brief History of SEO
- Early Days (the 1990s): The concept of SEO began with the launch of the first search engines like Archie and later, Yahoo and AltaVista. Keyword stuffing and meta-tag manipulation were common practices.
- The Rise of Google (2000s): Google’s introduction of PageRank revolutionized SEO. Link building became a crucial factor, and black-hat practices like keyword stuffing were penalized.
- Algorithm Updates (2010s): Google introduced significant updates like Panda, Penguin, and Hummingbird, emphasizing content quality, relevancy, and user experience.
- Modern SEO (2020s): SEO now focuses on user intent, mobile-friendliness, Core Web Vitals, and AI-driven algorithms like Google’s RankBrain.
Importance of SEO
- Increased Visibility: SEO helps websites rank higher in SERPs, ensuring they are more visible to potential customers.
- Cost-Effective Marketing: Unlike paid advertising, organic traffic driven by SEO is free and sustainable.
