What is SEO and Why Does It Matter?
Search Engine Optimization (SEO) is the practice of improving your website to increase visibility in search engine results pages (SERPs). When done correctly, SEO drives organic traffic, builds brand authority, and generates qualified leads without paid advertising costs.
In 2026, SEO remains the most cost-effective digital marketing strategy with ROI averaging 22:1 for established campaigns. This guide covers everything from basic fundamentals to advanced techniques.

Four types of search intent determine your SEO strategy:
