Pay-per-click (PPC) advertising and search engine optimization (SEO) are two of the most important strategies in digital marketing. Both aim to increase visibility in search engines and drive traffic to websites, yet they operate in very different ways. Understanding the difference between PPC and SEO helps businesses choose the right approach, set realistic expectations, and build balanced marketing strategies.

This article explains the key differences between PPC and SEO, how each works, their advantages and limitations, and when to use them together.
