SEO

Search engine optimization (SEO) is the process of improving the quality and quantity of website traffic to a website or a web page from search engines. SEO targets unpaid traffic (known as "natural" or "organic" results).

For SaaS, SEO is a long-term compound interest play. Ranking for high-intent keywords (e.g., "best CRM for small business") brings in high-quality leads at a near-zero marginal cost per click.
