Search engine marketing

While there are a few broader definitions, search engine marketing (SEM) generally means pay-per-click advertising in search engines such as Google or Bing. In a nutshell, we create ads which are displayed in search engines, and you get charged each time someone clicks on those ads (hence, the term “pay per click”, or “PPC”). The major players are Google AdWords, Bing Ads, and Yahoo Ads.
