Search Engine Marketing (SEM) is a digital marketing strategy used to increase a website’s visibility on search engine results pages (SERPs) through paid advertising. It involves running targeted ads on platforms like Google Ads or Bing Ads, where businesses bid on specific keywords relevant to their products or services. When users search for those keywords, the paid ads appear at the top or bottom of the search results, helping businesses attract potential customers instantly. SEM allows precise audience targeting, measurable results, and faster visibility compared to organic SEO, making it an effective way to drive traffic, generate leads, and boost conversions.
