The world of websites can be littered with never-heard-before terminology. It can be confusing and complicated. In the digital realm, the acronyms “SEO” and “SEM” are two of the most important terms you should be familiar with. Both SEO and SEM, when incorporated into your business strategy, can be instrumental in achieving the next level for your brand or service. But what is SEO vs. SEM?
To improve traffic, ranking, and visibility, one technique used is referred to as “search marketing”. Two categories within this technique include SEM (Search Engine Marketing) and SEO (Search Engine Optimization). What is search marketing? By appearing on SERPs (search engine results pages), it’s a tactic that helps generate attention to a brand or service. The two major search marketing categories are SEM and SEO.
In the improvement of visibility and traffic in search results, a significant role is played by both of these. Though they work with the same outcomes and intentions, in essence, the two techniques are quite the opposite of each other (with some similarities that will be explored later). The organic strategy is the main area in which these two search marketing techniques differ.
