SEM
Online ad strategy
SEM is an acronym with two main meanings in technical fields.
In microscopy, it stands for scanning electron microscope, a device that produces highly magnified images by scanning a focused electron beam across a sample.
In digital marketing, SEM means search engine marketing—paid advertising strategies to increase visibility in search results, distinct from organic SEO.
Context usually clarifies which meaning applies. (Lowercase sem is informal for semester.)
