What is SEM- Search Engine Marketing?

What is SEM (Search Engine Marketing? Is SEM the Same as PPC?

If you’re trying your hand at digital marketing, then you’ve probably come across the words SEM (Search Engine Marketing), SEO (Search Engine Optimization), and SEO Marketing. And I bet that like most, you probably thought they were the same thing; after all, they do have the words “Search Engine.” So, are they the same? 

If you’re a bit more advanced and know that SEO and SEM have some similarities, then you probably think that SEM and PPC are the same. But are they?

Search Engine Marketing (SEM) and Pay-per-Click (PPC) are two terms that often get thrown around interchangeably. However, while they share some similarities, they are not the same thing.

SEM encompasses a range of strategies and tactics designed to improve a website’s visibility and ranking on search engine results pages (SERPs), primarily through paid advertising. On the other hand, PPC refers specifically to the paid advertising model where businesses pay a fee each time someone clicks on one of their ads. So, what exactly is SEM, and how does it differ from PPC?

What is SEM (Search Engine Marketing)?

Search Engine Marketing, or SEM, is a digital marketing strategy that focuses on improving a website’s visibility and ranking on search engine results pages (SERPs). The main goal of SEM is to increase the quantity and quality of traffic to a website through both organic and paid search strategies.

What is the Difference Between SEM and SEO?

The difference between Search Engine Marketing (SEM) and Search Engine Optimization (SEO) is that the latter is a subset of the former. SEO is a strategy that focuses solely on improving a website’s ranking in organic search engine results pages (SERPs) through various tactics such as optimizing website content, improving website structure, and building high-quality backlinks.

SEM, on the other hand, encompasses a range of tactics, including both paid and organic search strategies.



How Does SEM (Search Engine Marketing) Work?

Let’s do something practical- a search on Google! I’ll search for the words “baby walker”.

SEM paid and organic traffic

Please note that for this article, we’ll focus on Google; but feel free to use your preferred search engine.

From the screenshot above, you can see Alibaba and Jumia have the top three spots on the search engine result page (SERP) and have the “Sponsored” tag. These are what are referred to as paid positions because Alibaba and Jumia have paid Google for that spot.

This is how SEM works- businesses bid on keywords related to their products/services, and the more they bid and the more relevant their content is, the higher chances they have of appearing on top of SERP. The bidding process is what we call an “Ad Auction.”

How Does an Ad Auction Work?

When you refer to the above screenshot, you’ll see that there are three spots at the top: one for Alibaba and two for Jumia. Depending on your location, you may also see some ads when you scroll down toward the end of the page.

So how does Google determine which ad to display on top? How do you get your ads to the top of the first page?

When someone searches on a search engine, the search engine uses a complex algorithm to determine which ads to display and in what order. The algorithm takes into account several factors, including the maximum bid amount, the ad relevance to the search query, and the quality of the landing page that the ad leads to.

Let me break down the new terms for you

  • Bid amount:  The maximum amount you’re willing to pay for a single click on your ad.
  • Ad relevance and quality: How relevant and useful your ad is to the keyword that’s been searched. For example, if you’re selling running shoes and someone searches for “running shoes,” an ad that talks about how great your products are is more likely to be relevant than one with a generic description of running shoes.

Search engines, however, strive to provide the most relevant and useful information to users. This means that even if your ad has the highest bid amount, it may not be displayed if it is not relevant or does not provide a good user experience.

Once the ad auction is complete, the winning ads are displayed at the top of the search engine results pages (SERPs).

What is PPC (Pay Per Click)?

PPC, or pay-per-click, is a popular form of digital marketing where advertisers basically “pay” to be featured in relevant searches for their target audience. It works by allowing advertisers to bid on certain keywords or phrases related to their product or service, with the winner of the auction appearing at the top of the results page whenever someone searches for those terms.

What does PPC mean in marketing

The cost of these campaigns varies depending on the chosen keyword – the more popular or competitive it is, the more advertisers will have to pay to appear on the advertising platform. This presents a great opportunity for any company looking to acquire new customers quickly since they only pay for their ads when they are clicked by potential customers, making PPC a very affordable option compared to traditional forms of advertising. 

Another advantage of PPC advertising is its measurability. Advertisers can track key metrics such as click-through rates (CTR), conversion rates, and cost-per-acquisition (CPA) to determine the effectiveness of their campaigns and make data-driven decisions about where to invest their marketing dollars.

Other than search engine advertising, PPC can also be used for social media marketing, display advertising, and other forms of digital marketing.

This brings us to our initial question: Is SEM the same as PPC?

The answer is both yes and no. SEM (Search Engine Marketing) encompasses all marketing efforts that use paid search ads, but it includes more than just using PPC for search engine advertising. It also covers organic search tactics like SEO (search engine optimization), content marketing, and other strategies to increase website visibility and draw in traffic.

In essence, SEO and PPC are both part of a broader SEM strategy.

How to Build an Effective SEM (Search Engine Marketing) Strategy

Search Engine Marketing (SEM) is a complex and multifaceted digital marketing strategy that involves several key components. Here are some of the most important components of an effective SEM strategy:

Keyword Intent:

The first step in developing an SEM strategy is to identify the keywords that your target audience is using to search for products or services related to your business. It’s important to understand the intent behind these keywords, as this will inform your ad copy and landing page content. For example, if someone searches for “best coffee shops near me,” their intent is likely to find a local coffee shop to visit.

Keyword Volume:

Once you have identified your target keywords, you need to determine the search volume for each keyword. This will help you prioritize your keywords and allocate your budget accordingly. You can use keyword research tools to estimate the search volume for each keyword.

Keyword Cost:

Another important factor to consider is the cost of each keyword. Keywords with high search volume and high competition will typically have a higher cost-per-click (CPC). It’s important to balance the cost of keywords with their potential ROI.

Campaign Organization:

To effectively manage your SEM campaigns, you need to have a well-organized account and campaign structure. This includes setting up campaigns, ad groups, and keywords in a logical manner. Each campaign should have a specific goal and target audience, and each ad group should be focused on a specific theme or set of keywords. This allows you to optimize your campaigns more effectively and make data-driven decisions.

Ad Copy:

The ad copy is one of the most important components of an SEM strategy. It’s important to create ad copy that is relevant, compelling, and aligned with the user’s intent. Your ad copy should include the keywords you are targeting, as well as a clear call-to-action that encourages users to click on your ad.


In conclusion, Search Engine Marketing (SEM) is a powerful digital marketing strategy that allows businesses to reach their target audience and drive more traffic to their website through both organic and paid tactics.

SEM is an umbrella term that encompasses both organic search engine optimization (SEO) efforts as well as paid search engine marketing (PPC). Whereas SEO focuses on improving your website’s ranking for specific keywords organically, PPC is all about paying for ads to appear as the top search result for a given keyword.

With organic SEO, your website may take months or even years to reach the coveted first page of Google’s SERPs–if it ever does. On the other hand, PPC campaigns can get your website onto the first page immediately and keep it there as long as you are willing to pay for the ads.

Ultimately, SEM is not just about SEO or PPC, but both working together. When implemented correctly and strategically, SEM will ensure that your website is seen by the right customers at the right time.
