In order to boost visibility, increase traffic, and produce leads or sales, search engine advertising (SEA), a subset of digital marketing, is posting paid advertisements on search engine results pages (SERPs). When people search for relevant terms, SEA enables businesses to bid on particular keywords to place their advertising at the top of search results, in contrast to SEO, which concentrates on organic search rankings.Businesses who want to swiftly expand their online presence and connect with people who are actively looking for what they have to offer must use search engine advertising. SEA efficiently boosts brand visibility and drives conversions with focused campaigns, continuous optimization, and quantifiable outcomes.
