SEM vs SEO
Think of SEM as the umbrella and SEO as one half of it, with PPC as the other. SEO earns organic placements through optimisation; paid search buys placements through ads. A complete search strategy usually combines both - paid for speed and testing, organic for durable, cost-efficient traffic.
Pro tip
When someone says "SEM", clarify whether they mean paid search only or paid plus organic - the term is used both ways and it changes the scope.
Key takeaways
SEM is the broad practice of getting visibility in search.
Traditionally it covers both SEO and paid search.
Many marketers now use SEM to mean paid search (PPC).
A complete search strategy combines both.
