Introduction
Search Engine Optimization (SEO) refers to the set of techniques and strategies used to enhance the visibility of a website or web page in search engine results pages (SERPs). The primary goal of SEO is to increase organic (non-paid) traffic to a website by achieving higher rankings for relevant search queries.
Historical Context
The history of SEO dates back to the mid-1990s when the first search engines were introduced. As websites proliferated, it became evident that some sites appeared higher in search results than others. This led to the development of early SEO tactics, primarily focused on keyword usage and meta tags.

SEO can be broadly categorized into three main types:
- On-Page SEO: Involves optimizing individual web pages to rank higher and earn more relevant traffic. Key aspects include keyword optimization, meta tags, content quality, and internal linking.
- Off-Page SEO: Focuses on external factors that influence rankings, such as backlinks from other websites, social signals, and online reputation.
- Technical SEO: Ensures that a website meets the technical requirements of modern search engines. It includes aspects like site speed, mobile optimization, indexing, and structured data.
