Examples of SEM platforms

When creating your SEM strategy, the first step is to select a platform that aligns with your business requirements. There are several options available, each with its advantages and disadvantages. Here are three examples of commonly used platforms for SEM:

Google Ads

Google Ads is a popular SEM platform (Search Engine Marketing). It lets advertisers show their ads on Google’s search engine results pages (SERPs), partner websites, and mobile apps.

You only need an account and a minimum budget of $10 daily to use Google Ads. You choose the keywords you want to target, and your ads will automatically appear when people search for those keywords.

The platform can be complicated, especially when figuring out your keyword strategy. However, you’ll get access to powerful tools and lots of data to help you.

Microsoft Advertising

Microsoft Advertising (formerly Bing Ads) allows advertisers to display ads on Bing search engine results pages and partner websites, including Yahoo. It generally has lower costs per click (CPC) compared to Google. 

You can easily set up campaigns to target different time zones, which is excellent for reaching international audiences. You can customize settings for individual ad groups without changing your entire campaign.

It stands out from Google because Microsoft Advertising provides more choices for budgeting, targeting specific locations, and distributing ads across different networks. These options can help you optimize your SEM campaign effectively.

Yahoo! Gemini

Yahoo! Gemini is Yahoo’s advertising platform for search and native ads. It combines both types of advertising in one place. Native ads are preferred for building trust and are great for inbound marketing. 

Yahoo! Gemini’s native ads include content recommendation boxes and stream ads, which catch prospects’ attention. They target engaged users, making them more receptive to your content.

To choose the right SEM platform, consider the following factors:

  • Audience: Analyze your target audience and their search behavior to determine which search engine they will most likely use.
  • Budget: Evaluate your budget and the cost per click for your desired keywords on each platform.
  • Features: Consider each platform’s features and ad formats and determine which aligns best with your advertising goals.
  • Competition: Assess the level of competition in your industry on each platform to gauge the potential cost and effectiveness of your ads.
  • Goals: Define your advertising goals, such as increasing website traffic, generating leads, or boosting sales, and choose the platform that best aligns with those goals.

How does SEM work?

Ranking your website higher than organic search results is an effective strategy to attract more customers and increase your revenue. So, how does Search Engine Marketing (SEM) work? As most businesses use Google, we will use it in our explanation.

When you search on Google, there’s a process determining which ads will appear and in what order. This process is called the ad auction. Whenever you search, an auction takes place to decide which ads will be displayed and where they will appear on the page.

Below are three mechanics to help you understand how Google Ad Auction works:

3 Steps of a Google Auction

Search relevance

Google searches for ads that contain keywords related to a search. First, you must focus on the keywords you want to bid on and the maximum amount you will pay for each click. The cost will vary based on the industry your business belongs to.

Eligibility filtering

Google’s system goes through a filtering process to eliminate ads that are not eligible. It ensures that only ads appearing on searches with significant commercial intent are displayed. Moreover, it separates advertisements that target a different country or violates Google’s policies, ensuring compliance and relevance.

Ranking & displaying

Finally, the ads appear on the search engine. The position of the search is not determined by the highest bid, like a regular auction. Winning the ad auction depends on these five factors:

Factors that determine google's ad auction
  1. Maximum bid: The most you’re willing to pay for a click on your ad.
  2. Quality score: Google Ads uses a formula to assess how relevant and useful your ad is to users.
  3. Impact of ad extensions: Additional information you provide in your ad, such as a phone number or links to specific pages.
  4. Ad rank: Ad rank combines your bid and the quality of your ad and landing page. Google requires a certain level of quality for ads to appear in higher positions.
  5. Ad context: When determining ad rank, Google considers factors like the search term used, the user’s location, the search time, the device used, and more.

Components of SEM

Search Engine Marketing (SEM) involves various components essential for successful online advertising campaigns. Here are the key elements of SEM:

Keyword research

Keyword research is the foundation of SEM. It involves identifying and selecting the most relevant and effective keywords that potential customers will likely use when searching for products or services. Thorough keyword research helps optimize ad targeting and improve campaign performance.

Ad Copy Creation

It is crucial to create ads that grab people’s attention and make them want to click on them. These ads should be short and easy to understand and highlight what makes your products or services unique. When your ads are well-written, more people will click on them and visit your website.

Landing page optimization

A landing page is where users land after clicking on your ads. Optimizing landing pages is crucial to ensure a seamless user experience and maximize conversions. Elements such as relevant content, clear call-to-action (CTA), user-friendly design, and mobile responsiveness contribute to successful landing page optimization.

Performance tracking & analytics

Tracking your SEM campaigns’ performance is essential to measuring success and making data-driven decisions. Performance tracking involves monitoring critical metrics like click-through, conversion, cost-per-click, and return on investment (ROI). Analytics tools provide insights into campaign performance, enabling you to optimize strategies and allocate resources effectively.

SEM best practices

Regarding SEM (Search Engine Marketing), following best practices is essential for the best results. By using these strategies, businesses can make their ad campaigns more effective and reach their target audience more quickly. Let’s look at some SEM best practices that can help companies get the most out of their online advertising.

Thorough keyword research

When planning your SEM campaigns, it’s crucial to do thorough keyword research. It means finding the right words and phrases that match what your target audience is searching for and are relevant to your products or services. To help with this, you can use tools or platforms explicitly designed for keyword research, such as Google Keyword Planner, SEMrush, or Moz Keyword Explorer.

When conducting keyword research, thinking beyond just the apparent keywords is essential. Consider terms that may attract customers at different stages of the buying process. 

For example, think about words that relate directly to your business and terms that intersect with your customers’ problems and expertise. Expanding your keyword choices allows you to reach potential customers at various stages of their decision-making journey.

Conduct A/B testing

A/B testing is a helpful method that compares two versions of something to see which works better. In SEM, you can use A/B testing to create different versions of your ads and landing pages. 

By comparing elements like headlines, images, calls to action, or even the entire ad format, you can gather data on what your audience likes more. This data-driven approach helps you improve your campaigns by using the versions that perform best and making adjustments to your messaging and design.

Personalize your ad campaigns

SEM campaigns often follow a structured approach that uses tactics like dynamic keyword insertion (DKI) to create specific and targeted ads in large quantities. While this can be effective, it’s essential to go beyond the formula and personalize your ad campaigns for better results.

Research from McKinsey shows that personalized ads can lead to up to 30% greater efficiency in marketing spend. So, it’s worth investing time and effort into tailoring your messaging, offers, and ad formats to match the preferences and needs of your target audience.

Consider essential factors like demographics, interests, and browsing behavior to create ads that feel relevant and captivating to individual users. Personalizing your ads increases the likelihood of grabbing attention, driving more engagement, and boosting conversions.

Be adaptable

Adaptability’s essential because things constantly change in the digital world. Monitor search engine updates, industry trends, and how people behave online.

Don’t be afraid to try new tools and technologies to improve your campaigns. Be ready to change your plans and methods as needed. By being flexible and proactive, you can stay ahead and ensure your SEM efforts continue working well, even when things constantly change.

Optimize your campaigns constantly

Search engine marketing (SEM) is a continuous process that needs constant tweaking to get better results. To improve your performance:

  1. Regularly check your campaign data and monitor essential metrics like how often people click on your ads, how many clicks lead to actual sales or conversions, and the return you get on the money you spend on ads.
  2. Look for patterns or trends in the data and figure out areas where you can improve things.
  3. Use the data to guide your decisions on the keywords you use, the words and phrases in your ads, how much you bid on keywords, and the pages you direct people to when they click on your ads.

By consistently making these adjustments based on real-time data, you can make your SEM efforts more effective and efficient.


If you want to take your business to the next level, mastering SEM is crucial. It lets you connect with your target audience when they’re actively searching for what you offer, leading to increased website traffic and improved sales.

It’s important to understand that SEM is different from SEO. While SEO focuses on improving organic rankings to gain free traffic, SEM involves ongoing monitoring, testing, and optimization to achieve optimal outcomes.
