Flowchart showing the structure of ad groups in Google AdWords for better performance.

Setting up Google Ads campaigns can feel overwhelming, especially when your ads aren’t performing as expected despite spending a significant budget. The culprit is often hiding in plain sight: your ad groups’ Google Adwords structure. Poor organization leads to irrelevant ad displays, wasted spending, and frustrating low quality scores that drive up your costs. Let’s change that!

This comprehensive guide will show you how to structure your ad groups for maximum performance. You’ll learn the relationship between campaigns and ad groups, step-by-step methods for creating theme-based groups, advanced strategies like SKAGs, and optimization techniques to transform your account’s performance. These proven approaches have helped countless advertisers improve their quality scores dramatically while reducing cost-per-click.

Understanding the Google Ads Hierarchy

How Campaigns, Ad Groups, Keywords, and Ads Work Together

Before diving into structural strategies, let’s clarify how the Google Ads system works. Think of your account as a filing system:

  • Account – Contains all your campaigns and billing information
  • Campaigns – Sets your budget, targeting options, and network selections
  • Ad Groups – Contains your keywords and ads grouped by theme
  • Keywords – The specific terms triggering your ads
  • Ads – The actual messages shown to users

The relationship between these elements is crucial. Your campaign settings control when and where your ads appear, but your ad groups’ Google structure determines the relevance between search queries, keywords, and ad copy—the primary factor in quality score calculations.

Why Quality Score Matters

Quality Score directly impacts:

  • Ad position
  • Cost-per-click
  • Impression share
  • Overall campaign profitability

Google rewards relevance with lower costs and better positioning. A well-structured account can achieve the same visibility at a fraction of the cost of a poorly organized account.

Creating Effective Theme-Based Ad Groups

Keyword Research and Grouping Principles

Start by conducting thorough keyword research using:

Once you have your keywords, follow these principles for grouping:

  • Semantic Relevance: Group keywords that share similar intent
  • Volume Balance: Aim for groups with comparable search volumes
  • Landing Page Alignment: Keywords should point to the most relevant page
  • Size Control: Limit ad groups to 10-20 keywords (fewer is often better)

Step-by-Step Ad Group Creation Process

  • Categorize keywords by product, service, or customer need
  • Further divide these categories into specific themes
  • Create ad groups based on these themes
  • Write at least 3 ads per ad group that specifically address the theme
  • Implement negative keywords in AdWords to prevent overlap between groups

For example, a dental practice might have campaigns for “Dental Services” and “Cosmetic Dentistry,” with ad groups like “Teeth Whitening,” “Dental Implants,” and “Invisalign” under the appropriate campaigns.

Advanced Strategy: Single Keyword Ad Groups (SKAGs)

What Are SKAGs and When to Use Them

Single Keyword Ad Groups represent the pinnacle of ad group relevance. As the name suggests, each ad group contains just one keyword (though in multiple match types). This structure allows for:

  • Hyper-relevant ad copy that can include the exact keyword
  • Precise performance data for each keyword
  • Maximized quality scores through perfect keyword-to-ad alignment
  • Granular bid management

SKAGs work best for:

  • High-value keywords
  • Terms with significant traffic
  • Competitive industries where quality score advantages matter most

Implementing SKAGs Effectively

To implement SKAGs:

  • Identify your most important keywords
  • Create an ad group for each keyword
  • Include the keyword in exact, phrase, and modified broad match
  • Write ads that incorporate the exact keyword in headlines and descriptions
  • Create dedicated landing pages or sections that perfectly match each keyword
  • Focus on adding negative keywords to AdWords to prevent cannibalization

While powerful, SKAGs require more management time. A hybrid approach works best for most advertisers – using SKAGs for top-performing keywords while maintaining theme-based groups for others.

Optimization Techniques for Ad Groups

Negative Keyword Management

When you effectively add negative keywords to AdWords, it prevents your ads from showing for irrelevant searches. For each ad group:

  • Review search term reports weekly
  • Add irrelevant terms as negative keywords
  • Apply negatives at the appropriate level (campaign or ad group)
  • Create shared negative keyword lists for terms that apply across multiple campaigns

Proper negative keyword targeting can dramatically improve CTR and conversion rates while reducing wasted spending. Learning to add negative keywords to AdWords is essential for ongoing account optimization and can save you significant budget over time.

Ad Relevance and Testing

For each ad group:

  • Ensure ads contain the primary keywords from the group
  • Create at least 3 variations with different headlines and descriptions
  • Include a strong call-to-action in each ad
  • Enable responsive search ads to test multiple combinations
  • Review ad strength indicators and make recommended improvements

Let your testing run until statistical significance before making decisions.

Regular Ad Group Maintenance

Establish a maintenance schedule:

  • Weekly: Review search terms and add negatives
  • Biweekly: Check performance metrics and adjust bids
  • Monthly: Evaluate ad performance and replace underperforming ads
  • Quarterly: Audit overall structure and consider reorganization

Fixing Low Quality Score Problems

Diagnosing Structural Issues

Low-quality scores often stem from poor ad group structure. Watch for these warning signs:

  • Keywords with quality scores below 5/10
  • Ad groups containing more than 20 keywords
  • Keywords with low CTR but high impression volume
  • Ad groups with widely varying themes
  • Ads that don’t contain the primary keywords

Restructuring Process

To fix a problematic account:

  • Export your keyword data with quality scores and performance metrics
  • Identify your best and worst performing keywords
  • Create a new structure based on tighter themes
  • Prioritize your top converting or highest potential keywords
  • Implement the new structure alongside existing campaigns before pausing old ones

The path to improving quality score starts with proper organization. Most advertisers see improvements within 2-4 weeks after restructuring.
