Full definition
SEM is paid advertising on search engines. While SEO is organic, SEM pays for clicks (PPC). Advantage: instant results. Drawback: you pay for every click.
📌
Why it matters
Search engine marketing buys immediate visibility on queries you do not rank for organically. It is a paid shortcut, not a substitute for building.
🧮 A worked example
A new business with no history can appear at the top of results tomorrow for a commercial term — for as long as it pays per click.
⚠️ The common mistake
Running ads on terms you already rank first for organically. In many cases that buys clicks you would have had for free.
