Introduction

Search Engine Marketing (SEM) is the practice of using paid advertising on search engines like Google and Bing to promote websites and increase visibility.

The most common model within SEM is Pay-Per-Click (PPC), where advertisers pay only when users click their ads.

SEM works as the perfect complement to SEO: while SEO builds long-term visibility, SEM delivers instant reach and measurable results.
