Search Engine Optimization (SEO)

Definition

Search Engine Optimization (SEO) is the practice of increasing the quantity and quality of organic (non-paid) traffic to your website through search engine results. SEO has three main components: On-Page SEO (optimizing individual pages—content quality, keywords, title tags, meta descriptions, headers, images, URL structure, internal linking), Technical SEO (site infrastructure—page speed, mobile-friendliness, crawlability, security/HTTPS, structured data, XML sitemaps), and Off-Page SEO (external factors—backlinks, brand mentions, social signals, reviews, domain authority). SEO works because search engines (primarily Google) use 200+ ranking factors to determine which pages best answer search queries. Effective SEO requires: understanding target audience's search behavior, creating high-quality content that satisfies search intent, building technical excellence, and earning authority through backlinks. SEO is a long-term investment—results typically take 3-9 months but compound over years. 53% of website traffic comes from organic search on average.
