Search Engine Optimization
Also called SEO
Search engine optimization: earning visibility in unpaid search results by making your content and site match what people search for and what search engines reward.
Why it matters
SEO can become a compounding, low-cost acquisition channel, traffic that keeps arriving without paying per click. It is slow to build and easy to do badly, but for many startups it is the best long-term organic engine.
For example
A recipe app ranks first for thousands of dish searches, so it earns steady free traffic that keeps arriving without paying per click.
