What is SEM marketing?
SEM (Search Engine Marketing) is a digital marketing strategy focused on increasing website visibility in search engine results pages (SERPs) primarily through paid advertising. It involves managing paid campaigns (PPC - Pay-Per-Click) on platforms like Google Ads and Bing Ads, encompassing keyword research, ad creation, bidding strategies, landing page optimization, and performance monitoring. The goal is to drive targeted traffic, generate leads, and boost sales by appearing prominently for relevant search queries.
