Many people confuse SEM and PPC because both are connected to advertising on search engines like Google and Bing online. SEM means search engine marketing, which covers methods businesses use to appear more often in search results pages. PPC means pay per click, where advertisers pay whenever somebody clicks their advertisement online. PPC is normally considered part of SEM because it focuses mainly on paid search traffic and visibility. Some marketers use both terms like they mean exactly the same thing.
