Search Engine Optimization (SEO) is the process of improving a website’s visibility on search engines like Google, Bing, and Yahoo. It involves optimizing on-page elements such as keywords, meta tags, and content, as well as off-page factors like backlinks and social signals. The goal of SEO is to rank higher in search engine results pages (SERPs), which increases organic (non-paid) traffic to your site. SEO is divided into three main types: On-page SEO, Off-page SEO, and Technical SEO. Each plays a crucial role in making your website more discoverable and user-friendly. Effective SEO strategies can help your business attract qualified traffic, enhance brand credibility, and achieve long-term growth. Unlike paid ads, the traffic generated through SEO is free and sustainable over time, making it a cost-effective marketing strategy.
