What is SEM (Search Engine Marketing) in Advertising?

Defining exactly what SEM or search engine marketing is can be tricky, as different definitions exist depending on who you ask.

SEM is defined by the set of tools, techniques, and strategies that help optimize the visibility of websites and web pages through search engines. In summary, the goal of SEM is to achieve a better position in the search results of Google and other similar sites.

Typically, the search results pages of Google and other sites display two types of results:

  • Organic Results: To determine which results to show, the search engine uses an algorithm that identifies which websites best respond to a specific query. Google’s algorithm is based on relevance (web content) and authority (links from other pages). The set of techniques and tools used to position organic listings is known as SEO (Search Engine Optimization).
  • Paid Results: Unlike organic results, here the advertiser pays for each click. To generate traffic by buying ads on search engines, you’ll need to turn to search engine advertising solutions, like Google Ads. This system is also referred to as PPC (Pay-Per-Click) or CPC (Cost-Per-Click).

Search Engine Marketing covers both SEO techniques and search engine advertising. However, most marketing specialists use SEM to refer exclusively to search engine advertising, or paid results. To avoid confusion, in this article, we use SEM specifically to refer to search engine advertising and paid advertising.

Advantages and Disadvantages of SEM (Search Engine Marketing)

Undoubtedly, search engine marketing is a powerful tool for almost all types of brands. To assess when and how to use it, let’s explore some of its advantages and disadvantages.


  1. Highly Measurable: Tools like Google Ads provide you with very detailed reports on the progress of your campaign, ensuring you always know what’s happening with your ads. Plus, integration with Analytics allows for perfect control over your campaign.
  2. Real-Time Monitoring: The analytical interface lets you see what’s happening at each moment, allowing instant course correction if you’re not achieving the desired results.
  3. Pay-Per-Click Model: This means you only pay when you see results. You can control the maximum daily budget you’re willing to invest, as well as the maximum cost per click you can afford, ensuring the campaign remains profitable.
  4. Speed: Compared to other techniques like SEO or content marketing, search engine advertising enables you to achieve large-scale results relatively quickly.
  5. Accessible to All: Since the budgetary investment is scalable, this solution works for both large corporations and SMEs. All compete on an equal footing to reach the top positions for keywords.
  6. Targeting: Finally, another advantage is its vast targeting possibilities. By focusing on keywords, you reach an audience actively interested in what you offer. You can also filter by other factors like location, language, or behavior.


  1. Higher Long-Term Cost: To be clear, SEM only works as long as you pay for it. Although campaigns can be optimized over time to reduce cost-per-click, you still need to pay for each visit you get.
  2. High Level of Competition: Search engine marketing has become popular, and many companies compete for the same keywords. This competition can drive up costs and sometimes make it challenging to achieve a good ROI.
  3. Intrusive Nature: Unlike other solutions like native advertising, SEM involves “invading” the user’s space with content they didn’t seek. Moreover, if your target audience uses ad blockers, they may not even see your ads.
