Search Engine Marketing (SEM) is a form of online advertising that involves promoting a website by increasing its visibility in search engine results pages (SERPs) through paid advertising methods.
SEM typically involves paying for ads on search engines like Google, Bing, and Yahoo. These ads appear at the top of the SERPs or alongside organic search results and are labeled as "sponsored" or "ad" links. SEM ads can take several forms, including pay-per-click (PPC) ads, display ads, and retargeting ads.
With SEM, advertisers bid on specific keywords that are relevant to their business, and their ads will appear when users search for those keywords. Advertisers pay a fee each time a user clicks on their ad (hence the name "pay-per-click").
The goal of SEM is to drive traffic to a website, generate leads, and increase sales or other desired outcomes. By using paid advertising methods, businesses can target users who are actively searching for products or services like theirs, making it a highly effective form of online advertising.
