Structuring Ad Groups in Google Ads: SKAG vs. STAG

Posted by Jairo Gomez on Jul 8, 2024 11:49:11 AM

Understanding Google Ads goes beyond just grasping the fundamentals of PPC and applying best practices of Google Ads; it involves mastering advanced strategies that optimize campaign performance. Key among these strategies is the way you structure your paid search campaigns. The structuring techniques you choose are pivotal in harnessing the full potential of Google Ads, leading directly into specific methods like SKAG and STAG, which are two ad structuring strategies popular among digital marketers. 

Digital marketers and PPC specialists use SKAG and STAG as effective ad structuring methods for online advertising. While both have their advocates and detractors, understanding their nuances can significantly enhance your campaign's effectiveness.

Why Use Ad Groups in Google Ads?

Ad Groups are an essential component of successful Google Ads campaigns. As well as choosing the winning Google Ads bidding strategy,  Ad Groups can help CEOs, marketing professionals, and marketers get better results from their ad spend and campaigns. Here’s why:

Key Benefits of Using Ad Groups

  1. Organized Campaigns: Ad Groups allow you to organize your ad campaigns into specific, manageable themes. This organization improves the overall performance by ensuring that ads are highly relevant to the audience they’re targeting.
  2. Targeted Ads: With Ad Groups, you can create highly targeted ads for specific user groups. This increased relevance leads to better engagement and higher click-through rates.
  3. Performance Insights: Ad Groups provide a clear view of which ads are performing well and which aren't. This transparency enables informed decisions on ad spend, allowing you to allocate your budget more effectively.
  4. Enhanced Quality Score: Ad Groups can improve your ad's Quality Score, which affects ad costs and placements. Higher Quality Scores result in lower costs and better search result positions.
  5. Ad Variation Testing: Ad Groups offer the ability to test different ad variations within a theme. This testing helps optimize your ads, ensuring that you’re always using the most effective version.

Understanding SKAG (Single Keyword Ad Groups)

What Is SKAG?

Single Keyword Ad Groups (SKAG) is a way to organize ads. Each ad group focuses on one keyword. It includes variations in match types like exact, phrase, and broad match. The primary goal is hyper-targeted ads that closely match search queries, thereby improving relevance and performance.

Benefits of SKAG

  • Better Relevance: When you focus on one keyword, your ads will better match what users are searching for. This will improve the relevance of your ads and increase your Quality Scores.
  • Better Control: SKAGs provide granular control over bids and budgets for each keyword, allowing for more precise optimization.
  • Enhanced CTR: With more relevant ads, SKAGs typically see higher click-through rates (CTR), as users find exactly what they’re looking for.
  • Better Quality Scores come from relevance and CTR, leading to lower CPC.

Drawbacks of SKAG

  • Complexity: Managing numerous ad groups can become cumbersome and time-consuming, particularly for large campaigns.
  • Resource-Intensive: SKAGs require continuous monitoring and optimization, demanding more resources and expertise.
  • Potential Overlap: Keywords in different ad groups might overlap, leading to internal competition and inefficiencies.

Understanding STAG (Single Theme Ad Groups)

What Is STAG?

Single Theme Ad Groups (STAG) group similar keywords together under a common theme or topic. STAGs focus on a wide range of search queries related to a theme, instead of just individual keywords. This helps balance relevance and simplicity in search results.

Benefits of STAG

  • Simplicity: STAGs are easier to manage compared to SKAGs, making them suitable for complex campaigns with numerous keywords.

  • Efficiency: By grouping related keywords, STAGs streamline the campaign structure, reducing the need for constant adjustments.

  • Broader Reach: STAGs capture a wider array of search queries, potentially increasing impressions and visibility.

  • Cost-Effective: Fewer ad groups mean less time and resources spent on management, allowing for more efficient budget allocation.

Drawbacks of STAG

  • Lower Relevance: Grouping multiple keywords can dilute ad relevance, potentially impacting Quality Scores and CTR.
  • Less Granular Control: STAGs offer less precision in bid and budget control, which may affect optimization efforts.
  • Mixed Performance: Variations in keyword performance within a single ad group can complicate analyzing and optimizing performance.

Performance Analysis: SKAG vs. STAG

Both SKAGs and STAGs have their own strengths and weaknesses. The choice between the two depends largely on the specific goals and resources of the campaign. SKAGs offer higher conversion rates due to highly targeted ads and landing pages, but potentially higher CPA due to more intense management and fine-tuning required. STAGs, on the other hand, could have conversion rates due to less precise targeting, but potentially lower CPA due to reduced management time and broader appeal.

Understanding these differences and aligning them with your campaign objectives is crucial for optimizing paid search performance.

Implementing SKAG and STAG Strategies in Google Ads

Practical Tips for SKAG Implementation

  1. Keyword Research: Start with comprehensive keyword research to identify high-potential keywords for your SKAGs.

  2. Consistent Monitoring: Regularly monitor performance metrics and make necessary adjustments to maintain high relevance and CTR.

  3. Negative Keywords: Use negative keywords to prevent overlap and competition between ad groups.

Practical Tips for STAG Implementation

  1. Thematic Grouping: Group keywords based on common themes or topics to maintain relevance while simplifying management.
  2. Ad Customization: Customize ad copy to reflect the overarching theme of each STAG, ensuring it appeals to a broader audience.
  3. Performance Analyze: Regularly analyze keyword performance within each STAG and adjust bids or budgets as needed.
  4. Automation Tools: Leverage automation tools to streamline campaign management and improve efficiency.

As digital marketing evolves, so too will the strategies and tools used to optimize paid search ads in Google. Here are some trends to watch for:

  1. AI and Machine Learning will improve and automate campaign optimization for both SKAG and STAG strategies. Google AI powers Performance Max, to drive better performance and improve your conversion rates across Google’s advertising surfaces. Yo
  2. Advanced Targeting Options: New targeting capabilities may emerge, allowing for even more precise audience segmentation and personalization.
  3. Cross-Channel Integration: Seamless integration across multiple advertising platforms will enable holistic campaign management and performance tracking.
  4. Understanding user behavior: Better analytics will help us learn more about how users behave, leading to improved ad strategies.


Both SKAG and STAG offer unique advantages and challenges in the realm of Google Ads. While SKAGs provide unparalleled precision and control, they require significant time and resources to manage effectively. On the other hand, STAGs offer simplicity and efficiency but may compromise on relevance and performance metrics.

Ultimately, the optimal strategy depends on your specific business goals, resources, and target audience. Understand the advantages and disadvantages of each method and make some A/B or split testing. This will help you select the most suitable one for your Google Ads campaigns.
