Digital marketing term
SEM
SEM (Search Engine Marketing) is the practice of acquiring visibility and traffic through search engines—typically via paid search, and sometimes including SEO.
Detailed explanation
SEM covers the marketing activities used to appear in search engine results. In common industry usage it refers primarily to paid search (PPC) campaigns on platforms like Google Ads, though some teams treat SEM as a broader umbrella that also includes SEO.
In practice, SEM success depends on keyword strategy, ad relevance, landing page quality, conversion tracking, and reading performance alongside metrics such as CTR, CPC, and ROAS—not a single number in isolation.
