SEM stands for Search Engine Marketing and is the umbrella term for all marketing in search engines, both the organic side (SEO) and the paid side (SEA). In everyday usage, SEM is sometimes used incorrectly as a synonym for paid search alone, but strictly speaking it covers both.
An SEM strategy can contain both a plan for organic content and a budget for Google Ads, coordinated so the two support each other.
