What is Search Marketing?

You need to understand the terminology for this type of marketing before you can create a strategic search optimization strategy. So let’s start from the top. Search marketing refers to any tactics that help a brand gain attention by appearing on the results pages of the search engine (SERPs). It includes efforts to increase rankings and visibility of searches so you can drive more traffic to a website or webpage.

In search marketing, there are two major categories:

  • SEM – which uses PAID strategies to appear in search
  • SEO –  which uses ORGANIC strategies to appear in search

The main difference between SEM and SEO is SEM being a paid strategy and SEO being an organic strategy.

The definitions related to search marketing have evolved, like most things in the search industry. Some marketers may see SEM as a paragliding term that includes both paid and organic strategies. But we recommend breaking the terms into these distinct categories to make your marketing plan clear. Since these terms can be interchangeable and mean different things to different marketers, the terminology should always be clarified before working with search partners. To ensure that you approach the strategy with the same understanding, discuss the definitions with your marketing partners.
