Search Engine Optimization (SEO) is the process of optimizing a website to improve its visibility and ranking on search engine result pages (SERPs). In today's digital age, businesses of all sizes are using SEO to increase their online presence and attract more traffic to their websites. SEO is a complex and ever-evolving discipline that requires a combination of technical and creative skills to achieve success. In this article, we will explore the fundamentals of SEO, including its history, best practices, and how to measure success. History of SEO The history of SEO can be traced back to the early days of the internet when search engines first began to emerge. In the mid-1990s, search engines like Yahoo and AltaVista were the dominant players in the market. During this time, webmasters and SEO practitioners focused on keyword stuffing and other spammy tactics to improve their website's ranking on SERPs.

This algorithm was a turning point for SEO, and it paved the way for the modern approach to SEO we see today. Over the years, Google has made numerous updates to its algorithm, including the infamous Panda and Penguin updates, which targeted websites with low-quality content and spammy backlink profiles.
