Use campaigns for meaningful budget, location, or goal differences. Use ad groups for closely related customer needs.
Google Ads campaign structure is the way an account is organized.
The basic hierarchy is:
Account → campaigns → ad groups → ads and keywords
Each level has a different job. A clean structure makes it easier to control budgets, show relevant ads and see which services produce calls, customers and revenue.
The Simple Answer
Separate campaigns when the business needs different budgets, locations, bidding or advertising goals.
Inside each campaign, group closely related searches into ad groups. Each ad group should connect one clear customer need with a relevant ad and landing page.
The best structure is not the one with the most campaigns. It is the simplest structure that gives the business useful control.
The Google Ads Account Hierarchy
Google describes its account organization in three main layers: account, campaigns and ad groups. Ads and keywords sit inside the ad groups.
| Level | What it controls |
|---|---|
| Account | Access, billing and links to tools such as analytics |
| Campaign | Budget, bidding, locations, language, network and campaign goal |
| Ad group | A focused set of ads, keywords or targeting |
| Keywords | The searches the advertiser wants to reach |
| Ads | The message a potential customer sees |
| Landing page | The page a customer reaches after clicking |
Settings applied at the campaign level affect the ad groups inside that campaign.
If two services need different budgets or locations, they probably need separate campaigns. If they share those settings but answer different searches, they may only need separate ad groups.

What Belongs at the Campaign Level?
Create a separate campaign when you need independent control over:
- Budget
- Bidding strategy
- Geographic targeting
- Language
- Search, Display, Shopping or another network
- Conversion goal
- Schedule
- Brand versus non-brand traffic
Do not create a separate campaign merely because another campaign would make the account look more organized.
Every additional campaign splits the budget and conversion data. If several campaigns pursue the same customers with the same settings, consolidation may create a clearer answer.
What Belongs in an Ad Group?
An ad group should represent one clear service, product or customer need.
A garage-door company might use ad groups such as:
- Emergency garage door repair
- Broken spring repair
- Garage door opener repair
- New garage door installation
Each ad group should have:
- Related keywords
- Ads that directly answer those searches
- A landing page that matches the promise
Someone searching for emergency repair should not receive an ad focused on new door styles.
Google recommends grouping related ads with related keywords so the message is useful for the search.
A Simple Local-Service Campaign Structure
Here is a practical starting point for a garage-door company serving one market.
| Campaign | Ad groups | Why it is separate |
|---|---|---|
| Brand Search | Company name and common brand variations | Protects and measures searches for the business |
| Repair Search | General repair, spring repair and opener repair | Focuses on urgent service demand |
| Installation Search | New doors, replacement and custom doors | Different customer need and sales value |
The Repair campaign may contain three ad groups:
- General garage door repair
- Broken spring repair
- Garage door opener repair
This provides control without creating a separate campaign for every keyword.
How to Decide Whether to Split or Combine
Use this rule:
Split when the business decision is different. Combine when only the wording is different.
Split when:
- One service needs its own budget
- Locations have different capacity or economics
- The customer intent is meaningfully different
- A service needs a different landing page and sales process
- Brand searches must be reported separately
Combine when:
- The searches describe the same customer need
- The same budget and bidding strategy apply
- The same landing page answers the searches
- Separate campaigns would be too small to produce useful data
Structure Around Customers, Not Internal Departments
The customer does not know how the business is organized.
A company may have separate internal teams for repairs and maintenance, but customers may use the same searches for both. Another company may treat installation and repair as one department even though customers view them as completely different purchases.
Build the account around how people search and buy.
Ask:
- What problem is the customer trying to solve?
- How urgent is it?
- What page answers it?
- What is one customer worth?
- Does the business need separate budget control?
Keep the Customer Path Consistent
A strong ad group repeats the same idea from search to page:
Search → keyword → ad → landing page → call or form
Example:
- Search: broken garage door spring repair
- Keyword theme: broken spring repair
- Ad: Same-Day Garage Door Spring Repair
- Landing page: Garage Door Spring Repair
- Main action: Call for service
That consistency can improve the customer experience and make the campaign easier to diagnose.
The Google Ads Quality Score guide explains how ad relevance and landing-page experience fit into this process.
Common Campaign-Structure Mistakes
One Campaign for Everything
Mixing services, products, locations and goals makes budget control difficult.
One Campaign for Every Keyword
Extreme separation creates maintenance work and leaves each campaign with little data.
One Ad Group With Unrelated Keywords
One ad cannot clearly answer several unrelated customer needs.
Mixing Brand and Non-Brand Searches
People who already know the business behave differently from people discovering it. Separate reporting prevents easy brand sales from hiding weak new-customer campaigns.
Copying the Website Menu Exactly
The website can inspire the structure, but the account should reflect real searches and customer intent.
Rebuilding the Account Without a Reason
Google warns that major reorganization can discard useful history. Change the structure when it improves a business decision, not because a new diagram looks cleaner.
A Simple Setup Checklist
Before launching, confirm:
- Each campaign has one clear business goal.
- Services with different budgets or locations are separated.
- Brand and non-brand traffic are easy to distinguish.
- Each ad group covers one clear customer need.
- Keywords, ads and landing pages match.
- Conversion tracking measures calls, leads and sales.
- The budget is large enough to produce useful activity.
- Naming makes reports easy to understand.

Talk to Darlington →Google Ads Campaign Structure FAQ
What is the basic Google Ads campaign structure?
An account contains campaigns. Campaigns contain ad groups. Ad groups contain ads and keywords.
How many campaigns should a Google Ads account have?
There is no universal number. Create enough campaigns to control meaningful differences in budget, location, goal or customer intent. Avoid splitting the account so far that every campaign lacks data.
How many ad groups should be in one campaign?
Use as many as needed to represent the campaign's distinct customer needs. Each ad group should remain focused and support a relevant ad and landing page.
Should every service have a separate campaign?
Not automatically. Use a separate campaign when the service needs its own budget, location, bidding or goal. Otherwise, a separate ad group may be enough.
Should brand keywords have their own campaign?
Usually yes. Brand searches behave differently and should not hide the cost of acquiring customers who did not already know the business.
The Bottom Line
Good Google Ads campaign structure creates clear decisions.
Use campaigns for meaningful differences in budget, location and goals. Use ad groups for closely related customer needs. Keep keywords, ads and landing pages focused on the same result.
Then measure which structure produces customers and revenue.
