What is SEM?

SEM and SEO

Search Engine Marketing (SEM) and Search Engine Optimization (SEO) are often confused for one another. Indeed the terms are sometimes mistakenly used interchangeably. Put simply, SEM is a paid tactic and involves bidding on keywords to appear at the top of the Search Engine Result Pages (SERP) and paying each time a user clicks on the ad. In contrast, SEO involves proving the relevance of your website for certain key terms and phrases so that when people search the terms, a link to your website will appear without paying to be placed on the SERP.
