Search Engine Marketing Definition
Definition: Search Engine Marketing (SEM) is a digital advertising strategy that involves promoting websites by increasing their visibility on search engine results pages (SERPs) through paid advertising. Unlike SEO, which focuses on organic rankings, SEM involves placing sponsored ads—typically through platforms like Google Ads or Bing Ads—to target users based on keywords, location, device, intent, and behavior.
SEM combines targeted reach, real-time bidding, and performance analytics to help businesses appear at the top of relevant searches, drive traffic, and capture demand from high-intent users.
