A Google Ads Search campaign can have the right keywords, attractive ads, and a reasonable budget and still struggle to generate results if the account structure is poorly designed. One of the biggest problems advertisers face is either creating campaigns that are too broad or splitting them into so many tiny ad groups that there isn't enough data for Google to optimize effectively.
A modern Search campaign should create a clear connection between search intent, keywords, ads, landing pages, and conversions without unnecessarily fragmenting the data.
In this guide, you'll learn how to build a Google Ads Search campaign from the ground up, separate Brand and Non-Brand traffic, organize keywords into intent-based ad groups, use Exact, Phrase, and Broad match appropriately, structure campaign budgets, configure important ad assets, and align landing pages with ad groups for stronger relevance and Quality Score.
Start With Campaign Architecture, Not Keywords
One of the easiest mistakes to make when creating a Google Ads account is opening Keyword Planner and immediately building a huge keyword list.
Instead, start with the business structure.
Before creating campaigns, identify:
- What products or services are being advertised?
- Which searches represent different customer intents?
- Which locations are being targeted?
- Is Brand traffic being separated from Non-Brand traffic?
- Which landing pages exist?
- What conversion actions matter?
- How much budget is available?
This gives you the foundation for your campaign architecture.
A useful rule is:
You don't need a separate campaign for every keyword.
Why SKAGs Are No Longer the Default Structure
For years, advertisers were taught to use Single Keyword Ad Groups, commonly known as SKAGs.
The basic concept was simple:
For example:
Ad Group: Emergency Plumber London
- [emergency plumber london]
The advertiser could then create an ad specifically mentioning "Emergency Plumber London."
The idea was that tighter keyword-to-ad relationships would improve relevance and Quality Score.
The problem is that modern Google Ads matching and automation have evolved significantly.
Search behavior is not limited to one exact keyword phrase. A customer could search:
- emergency plumber london
- emergency plumbing service london
- plumber for emergency repairs london
- 24 hour emergency plumber
- emergency plumber near me
Creating separate ad groups for every variation can fragment data and create unnecessary management work.
Instead of building dozens of tiny ad groups, advertisers can organize keywords around shared search intent.
Build STAGs Around Search Intent
A more practical structure is an intent-themed ad group, sometimes referred to as a STAG or Single Theme Ad Group.
The objective isn't necessarily to have one keyword.
The objective is to group keywords that represent the same commercial intent and can use the same advertising message and landing page.
For example, a plumbing company could structure a campaign like this:
Ad Group: Emergency Plumbing
Keywords might include:
The exact keywords depend on the account's strategy and search behavior.
But the important point is that these searches share a common intent.
They can therefore use:
One relevant ad theme + one relevant landing page.
Ad Group: Boiler Repair
A separate ad group could contain:
The landing page can then focus specifically on boiler repair.
This creates a structure that is specific enough to maintain relevance without becoming unnecessarily fragmented.
The STAG Test
Before putting keywords into the same ad group, ask:
Can these keywords use the same ad without making the message feel generic?
Then ask:
Would the same landing page satisfy someone searching for all of these terms?
If the answer is yes, they may belong together.
If the search intent, offer, or landing page needs to be completely different, create a separate ad group.
This is more useful than simply asking how many keywords should be inside an ad group.
Separate Brand and Non-Brand Campaigns
One of the most important architectural decisions is separating Brand and Non-Brand traffic.
Brand Campaign
A Brand campaign targets searches related to the company's name or brand.
For example:
Non-Brand Campaign
A Non-Brand campaign targets searches describing the product, service, or problem.
For example:
These campaigns have fundamentally different search intent.
Brand searches often come from people who already know the company.
Non-Brand searches generally represent people searching for a solution or provider.
Keeping them separate gives you better control over:
- Budgets
- Reporting
- Search terms
- Ad messaging
- Bidding
- Performance analysis
It also prevents strong Brand performance from making the overall account appear healthier than the Non-Brand acquisition campaign actually is.
Use Campaign-Level Budgets Strategically
Campaign-level budgets determine how Google can distribute your advertising spend.
Suppose you have a total budget of: £100/day
You might initially divide it between:
- Brand Search: £10/day
- Non-Brand Search: £90/day
But don't treat those percentages as a universal rule.
Your allocation should reflect the business objective.
If Brand searches are already receiving significant organic visibility and the primary objective is new customer acquisition, you may want substantially more budget available for Non-Brand traffic.
For a new campaign, start with a deliberate allocation rather than allowing every campaign to compete for the same budget without a clear reason.
Avoid Excessive Campaign Splitting
Don't create separate campaigns for:
- Every keyword
- Every match type
- Every individual city
- Every minor service variation
Create a separate campaign when you genuinely need different control over something such as:
- Budget
- Location
- Language
- Business objective
- Brand vs. Non-Brand
- Product category
If two campaigns need exactly the same budget, targeting, bidding, and optimization approach, ask whether they actually need to be separate.
Organize Keywords by Intent
Keyword organization should follow what the person searching is trying to accomplish.
Consider a software company selling CRM software.
Instead of creating dozens of tiny groups, you could organize searches into themes such as:
CRM Software
Sales CRM
CRM for Small Business
Each group represents a distinct commercial intent that can support different ad messaging.
The landing page should also match that intent.
Match Types: Exact, Phrase, and Broad
Modern Search campaigns can use three primary keyword match types:
- Exact match
- Phrase match
- Broad match
They shouldn't automatically be treated as three stages where every advertiser must use all three.
Instead, think about the relationship between match type, search intent, conversion data, and bidding strategy.
Exact Match
Exact match gives advertisers tighter control over the searches that can trigger a keyword compared with broader matching options.
It can be useful when:
- Search intent is highly specific.
- You know which queries convert.
- You want to prioritize proven terms.
- You need tighter control over a particular commercial search.
For example:
could be used to prioritize a known high-value search theme.
But remember that exact match doesn't mean Google will only show the ad when the user's query is character-for-character identical to the keyword. Google uses close variants and matching based on search intent.
Phrase Match
Phrase match provides a broader reach than Exact while maintaining more control than Broad in many situations.
For example:
could capture searches expressing similar intent.
Phrase match can be useful when you have a known search theme but want to discover additional relevant variations.
The Search Terms report then becomes important.
You can identify:
- New relevant searches
- Irrelevant searches
- Negative keyword opportunities
- New keyword themes
Broad Match
Broad match can provide substantially wider reach and gives Google's systems more flexibility to identify searches related to the keyword's meaning.
But Broad Match should not be treated simply as:
"Use this when you want lots of clicks."
For conversion-focused campaigns, broad matching is most useful when the account has:
- Reliable conversion tracking
- Meaningful conversion data
- Appropriate Smart Bidding
- Strong negative keyword management
- A clearly defined conversion objective
Google recommends pairing broad match with Smart Bidding because the system can use auction-time signals to optimize toward the advertiser's conversion goal.
This is fundamentally different from using broad match simply to generate cheap traffic.
Match Types and Bidding Strategy
A practical framework looks like this:
| Situation | Possible Approach |
|---|---|
| New campaign with limited data | Tighter keyword control + careful search-term monitoring |
| Proven high-intent searches | Exact/Phrase can provide tighter control |
| Established conversion data | Evaluate Broad + Smart Bidding |
| Strong conversion tracking | Greater opportunity for automated bidding |
| Poor conversion tracking | Fix measurement before expanding automation |
This isn't a rigid formula.
Google Ads performance depends on the account, industry, search volume, conversion data, budget, and campaign objective.
The important principle is:
Don't give Google's automation more responsibility than your data can support.
Build Ads Around the Ad Group Theme
Once your ad groups are organized, write ads that directly reflect their intent.
For an ad group targeting: Emergency Plumber
your headlines might communicate:
- Emergency Plumbing Services
- 24/7 Emergency Plumber
- Fast Plumbing Help
- Book An Emergency Plumber
The ad shouldn't suddenly focus on unrelated services such as bathroom renovations.
The closer the connection between:
the clearer the user journey becomes.
Use Ad Assets to Increase Search Visibility
Ad assets provide additional information and can make the advertisement occupy more useful space on the results page.
Important assets can include:
Sitelinks
Use sitelinks to send users to relevant sections such as:
Callouts
Callouts highlight benefits or useful business information.
Examples:
Avoid making every callout sound like another headline.
Structured Snippets
Structured snippets can communicate categories, services, or features.
For example:
Use the appropriate predefined structured snippet header rather than forcing unrelated information into the asset.
Call Assets
For businesses that rely heavily on phone enquiries, call assets can make it easier for potential customers to contact the business directly.
Lead Form Assets
Lead form assets can allow eligible advertisers to collect lead information directly through Google's interface.
However, don't automatically add every available asset.
Each asset should support the campaign's objective and provide useful information to the searcher.
Align Every Ad Group With the Right Landing Page
This is one of the most important parts of campaign architecture.
Suppose you have these ad groups:
- Emergency Plumbing
- Boiler Repair
- Bathroom Plumbing
- Drain Unblocking
Sending all four to the same generic homepage creates unnecessary friction.
Instead:
- Emergency Plumbing → Emergency Plumbing landing page
- Boiler Repair → Boiler Repair landing page
- Drain Unblocking → Drain Unblocking landing page
The visitor should immediately see that they landed in the right place.
The landing page headline should reinforce the search intent.
For example:
- Search: Emergency Plumber London
- Ad: 24/7 Emergency Plumbing Services
- Landing page: Emergency Plumber London — Fast Local Response
That's a coherent journey.
Can This Improve Quality Score?
Google's Quality Score incorporates factors including:
- Expected CTR
- Ad relevance
- Landing page experience
Google describes Quality Score as a diagnostic tool rather than a KPI that should be directly optimized in isolation.
Therefore, don't build your entire campaign architecture simply to chase an 8/10 or 10/10 Quality Score.
Instead, build a campaign where:
The stronger this alignment, the better positioned you are to provide a useful search experience.
Quality Score can then help identify where that experience may be weaker.
Don't Over-Segment Your Campaign
Over-segmentation is one of the easiest ways to create a difficult-to-manage account.
Imagine a campaign with:
That's already hundreds of individual components to monitor.
If the campaign only generates a small number of conversions each month, you've also fragmented the data across many areas.
A simpler structure might contain:
with enough data to evaluate performance.
The exact number depends on the business.
There is no universal rule that every campaign should contain exactly five, ten, or twenty ad groups.
The structure should follow meaningful differences in search intent.
A Complete Campaign Architecture Example
Let's say you're advertising a Google Ads agency.
A simple Non-Brand campaign could look like this:
Campaign: Google Ads — Non-Brand
Ad Group 1: Google Ads Agency
Ad Group 2: PPC Management
Ad Group 3: Google Ads Management
Each ad group gets:
- Relevant keyword themes
- Relevant responsive search ads
- Relevant ad assets
- Relevant landing page
- Relevant conversion tracking
Campaign: Google Ads — Brand
Then create a separate Campaign: Google Ads — Brand with keywords related specifically to your company's brand.
This makes reporting much easier.

What a Modern Search Campaign Should Look Like
A strong Google Ads Search campaign isn't necessarily the campaign with the most keywords or the most ad groups.
It is the campaign where every layer has a clear purpose.
Think of the architecture as:
The goal is to make that journey logical from beginning to end.
Final Takeaway
The architecture of your Google Ads Search campaign can determine how easily you can manage, measure, and optimize it.
Instead of building dozens of SKAGs around individual keyword variations, organize keywords into intent-themed ad groups where the same messaging and landing page make sense.
Separate Brand from Non-Brand traffic when you need different budget and optimization control. Use Exact, Phrase, and Broad match according to your campaign's data and objectives rather than treating one match type as universally superior.
Most importantly, connect every layer:
That structure gives you a campaign that is easier to understand, easier to optimize, and less likely to fragment valuable data across unnecessary campaigns and ad groups.
A high-converting Search campaign isn't built by adding more keywords.
It's built by creating better connections between what people search for and what your business offers.
If you opened your Google Ads account today, would your current campaign structure make that connection obvious?
