Account Structure: Campaigns, Ad Groups, Ads
Google Ads account structure is the foundation of campaign performance. A well-structured account ensures relevant ads show for the right keywords, Quality Scores stay high, and budgets are allocated efficiently. Poor structure is the #1 cause of wasted ad spend in Google Ads accounts.
The Three-Level Hierarchy
- Level 1 — Campaign: Sets budget, campaign type, bidding strategy, location targeting, and network settings. Each campaign should represent a distinct product line, service category, or funnel objective. Example campaigns: 'Brand Keywords', 'Competitor Keywords', 'Service Line A', 'Service Line B'
- Level 2 — Ad Group: Contains a tightly themed group of related keywords and the ads that match those keywords. One ad group should contain 5-20 closely related keywords with the same user intent. Example: Ad Group 'Google Ads Services' contains keywords: 'google ads agency', 'google ads management', 'hire google ads expert'
- Level 3 — Ads: The actual text ads shown to users. Best practice: 3 Responsive Search Ads (RSAs) per ad group minimum. Each ad must contain the ad group's core keyword in the headline for relevance.
SKAG vs STAG Structure
- SKAG (Single Keyword Ad Group): One keyword per ad group — maximum relevance and Quality Score control, but labor-intensive to manage at scale. Best for: high-value keywords where CPA justifies the management overhead
- STAG (Single Theme Ad Group): Multiple related keywords in one ad group — more manageable, slightly lower relevance. Best for: most businesses managing campaigns without a dedicated PPC team
- Modern best practice: Theme-based ad groups (STAG) + Responsive Search Ads (RSAs) + Smart Bidding covers 90% of use cases effectively
