Google Ads account structure: campaigns, ad groups and keywords that stay manageable

Use campaigns when a control such as budget, bidding objective, targeting, schedule or campaign type must differ. Use themed ad groups for searches that can share one relevant message and one landing page.

Keep the structure as simple as those controls allow, because someone must understand, maintain and evaluate every split. Anyone who gives you an ideal campaign, ad group or keyword count hasn't asked what you sell.

Campaigns and ad groups have different jobs

For keyword based Search, the account contains campaigns and campaigns contain ad groups. Each ad group contains related keywords and the ads that answer them. Google's own account organisation page describes three layers: account, campaigns and ad groups. It puts the budget and the settings that decide where ads appear at the campaign level.

The account itself holds what every campaign shares.

Keep billing, user access and the linked accounts in the business's name. That way, a change of manager never means starting again.

One business account is the normal small business arrangement. Multiple accounts aren't automatically wrong. Separate legal entities, billing, access or markets can need another design. Our guide to setting up Google Ads for a small business covers the setup itself.

Below the account, each of the Google Ads campaign types organises things a little differently. The landing page is the ad's destination, not a fourth level of the account. Nor is there a rule that every group may use only one URL.

When should you create a separate campaign?

When a control has to differ. Separate a service when it needs:

• a protected budget

• a different objective or value target

• different campaign targeting or hours

• a different campaign type

Keep services together when those controls can sensibly be shared and distinct ad groups preserve the relevant message.

A different landing page alone does not need another campaign. It needs an ad group.

Urgent and planned work often differ in staffing, hours, economics and budget. That's why the electrician below splits them. But urgency alone isn't a mandatory split. Advertise 24 hour availability only when the business can answer at 3 am.

An ad promising it and a voicemail denying it is an expensive way to earn a bad review.

Our guide to high intent and low intent keywords covers the buying journey behind urgent and planned searches.

Locations

Ask whether capacity, travel cost, the offer or the required allocation actually differ between areas. If they do not, one campaign with the right location targeting serves both. A campaign for every suburb by default produces thin data and identical ads.

Standard campaign location targeting is a different thing from ad group level locations of interest in AI Max. AI Max is Google's optimisation layer for Search campaigns. Google's page on how AI Max for Search works says those locations reach customers by geographical intent. They do this even in keywordless matches. But they don't replace the campaign's service area controls.

Brand

If you buy brand traffic, separating it into its own campaign makes the budget and the reporting clearer. Brand clicks and non brand clicks behave differently. Blending them hides the real cost of a new customer.

Not every branded search comes from an existing customer. Not every non brand search comes from a new one. Don't assume paid brand activity or a lower branded cost per click is right for every account.

What we find in audits is a brand campaign nobody decided to run. Our audit sample is 180 Google Ads account audits from August 2021 to September 2026. Brand searches were clicking inside a campaign reported as non brand. That was the case in about 1 in 2 accounts we took over. A broad keyword that matches the business name is all it takes.

Build themed ad groups with relevant ads

A single theme ad group, a STAG, holds keywords that share a customer need, message and destination. A single keyword ad group, a SKAG, isolates one keyword. Themed groups are the practical default.

Google's account structure best practices say so directly. Move single keyword ad groups into themed ad groups. Consolidate tightly themed setups. Treat unnecessary segmentation as something that makes an account harder to manage and adapt.

Keep a narrower group where the message, the offer, the destination or a control requirement differs. One isolated keyword isn't wrong. But the label alone proves nothing about results.

That's an example of simpler organisation. It isn't evidence of faster learning, a lower cost per click or a better conversion rate.

The test is whether the searches share a useful ad and page. Switchboard upgrades can hold its wording variants. EV charger installation needs another message and another page. So it gets another group.

Job seekers do not belong with buyers at all. A compliance requirement that dictates exact wording needs control of every generated ad and destination. A single keyword label doesn't give you that.

How many ad groups and keywords?

As many as the relevance test produces and no more. Fixed counts of ad groups per campaign or keywords per group answer a question nobody should ask first.

Ask instead: can these searches share a useful ad and page? Is there enough activity to evaluate the split you're proposing?

Smart Bidding doesn't learn only inside an isolated ad group silo. So splitting a group doesn't give the algorithm a cleaner lesson. Google's best practice page notes that segmented traffic forces Smart Bidding to optimise for multiple targets separately.

No new group needs a universal minimum conversion count. But a group that will see six clicks a month cannot be evaluated against anything.

How matching affects your ad groups

Google's keyword matching page defines even exact match as searches sharing the keyword's meaning or intent. So none of the three match types is literal only.

Duplicating every keyword in every match type isn't required. Google's structure guidance says there's no additional benefit to multiple match types under Smart Bidding. That's because the duplicates segment the data. Putting match types in separate groups needs a reason.

Starting with phrase and exact and widening later is a reasonable choice, not a Google rule. Broad match needs a bidding and measurement setup that can handle it.

AI Max changes what any keyword list can promise. Google's AI Max setup page says new Search campaigns have it turned on by default. With it on, Google can match searches your keywords never named. It can also customise the ad text and send clicks to a page the ad group never listed.

Review those settings and the URL exclusions before you trust a keyword to page map. Our guide to Google Ads match types covers the matching detail and the controls.

For the ads themselves, see our guide on how to write Google Ads. It covers writing one that matches the theme.

A practical account structure for an electrician

An example Melbourne electrical business, not a real client. Assume emergency work needs its own budget and an after hours roster that the business actually staffs. Planned installations are quoted and booked in business hours. The brand campaign exists only if the business name is being searched. Even then, the cost of protecting it has to be justified.

The paths in the map are fictional teaching labels, not links. Emergency work is split out because it needs a protected allocation and a schedule that matches the roster. Urgency isn't the reason.

Planned installations share one campaign because they share a budget pool, hours and a quote request goal. The two ad groups keep their own messages and pages. Someone searching the business name wants the business, not a service page. So the brand campaign points at the homepage.

Each group has two or three representative keywords and a page that answers the search. Each also lists the business outcome its campaign optimises toward. Is a service page or a focused landing page the right destination? That's the subject of our guide to the Google Ads landing page versus homepage choice. Google Ads for trades carries the trade specific implementation.

The smaller budget version

A business that cannot fund three campaigns prioritises fewer services and combines compatible ones in one campaign. The ad groups still report by theme. That means you can see, say, that switchboard upgrades produced eight quotes and EV chargers produced two.

What you lose is a protected budget for each theme, not the ability to see service level performance. That distinction is the whole argument for starting simple.

Set budgets and conversion goals deliberately

Budget allocation and bidding are different decisions that get confused because the interface shows them side by side.

Google's shared budgets page defines it exactly that way. It limits shared budgets to Search, Shopping, Display and Video campaigns. It also excludes campaigns in an experiment and campaigns with a total budget. A shared budget is a spending pool, not a guarantee that each service receives a minimum.

A portfolio bid strategy coordinates bids across campaigns with compatible goals. On its own, it doesn't share budget. Google's page on linking a shared budget to a portfolio strategy covers the combination. It calls the pairing best practice for using a total budget efficiently. Which strategy to choose is covered in our guide to Google Ads Smart Bidding.

Google's Performance Max feature compatibility page says Performance Max doesn't support portfolio bid strategies or shared budgets. Allocate on demand, margin, qualification, close rate and the capacity to deliver the work. Treat every figure as an assumption until results arrive.

A margin assumption isn't a measured result. So nothing in the table says which campaign will return the most. Model each campaign on your own numbers before you split a real budget.

More services do not need more campaigns

A clinic is the opposite case to the electrician: several services, one campaign.

Assume one location, the same hours, one budget pool and one meaningful booking goal. Two themes keep two relevant messages without pretending each has a budget. The clinic needs no second campaign until a control differs. The map is an account example, not clinical advertising copy and not a targeting recommendation.

Choose goals that represent the intended result

Google's conversion goals page explains that a new campaign selects all account default goals for optimisation. A campaign can instead use goals you explicitly select, including a custom goal. A secondary action included in a custom goal is used for bidding. Outside a custom goal, secondary actions are observational.

So use account default goals when the campaigns share the business outcome. Use campaign specific goals for a real difference rather than for every campaign. The electrician is a fair case for it. Emergency work is judged on answered calls, installations on quote requests.

Check the selected goals and the primary actions together. Don't let a page view and three stages of the same lead count as equal outcomes.

For calls, a phone link click, a connected call and a qualified enquiry are different records. For a store, record purchases with meaningful values and duplicate protection. Use CRM outcomes where they exist. The implementation belongs to our guide to Google Ads conversion tracking setup.

Manage routing across Search and Performance Max

Start with the myth. Google's page on ad group and asset group prioritisation settles it. Keywords targeting the same domain do not compete with each other in the auction. That holds even when they could match the same search.

What overlap does is make routing and reporting harder to read. That's because you can't easily tell which group will serve.

On Search inventory, an eligible exact keyword identical to the search comes first. Next comes an identical phrase or broad keyword, or a Performance Max search theme. Then relevance and Ad Rank decide.

Budget, disapprovals, targeting and low search volume can change the result. Shopping and newer surfaces such as AI Mode follow other rules. So neither Search nor Performance Max always wins. For the full order and its exceptions, see our match types guide.

A retailer running both campaign types shows where they differ.

Each campaign has its own budget arrangement, not one per asset group. A Search ad group runs on keywords. A Performance Max asset group is a set of creatives built around a theme. Its search themes and audience signals guide the campaign rather than fence it.

Google's asset groups page notes what final URL expansion does. With it on, Google may replace your final URL with a more relevant landing page. Check the product selection, the brand settings and the final URL controls before launch. Our review of Performance Max for small businesses covers whether to run it at all.

Routing with negatives and brand exclusions

Exclude "hot water" from an emergency campaign only if that intent belongs elsewhere. Emergency hot water work must also be outside the campaign's scope. An exclusion blocks eligibility in one place. It doesn't guarantee that another campaign will serve. So check that the intended group is eligible and funded before you rely on the route.

Don't exclude "free" or "DIY" across a business that offers relevant services. The same goes for job related terms while it's recruiting. Build the lists from the search terms you see rather than from a template.

Where an exclusion sits decides its reach. An account level negative applies to Search and Shopping inventory across the account's eligible campaigns. A shared list reaches only the campaigns it's attached to. A campaign or ad group negative stays where you put it.

Brand exclusions are a separate control again. Google's page on brand exclusions in Search and Performance Max puts new Search brand lists inside AI Max. A new Search campaign already has it on. But older campaigns keep their existing brand settings outside it.

In Performance Max, brand exclusions cover Search, Shopping and YouTube search inventory. Never exclude your own brand where an intentional brand campaign should stay eligible.

Negatives match differently from keywords. Our guide to Google Ads negative keywords covers negative match types and brand exclusions in full.

Name and copy campaigns without creating a mess

Names help people navigate an account. They do not implement targeting, tracking or permissions. A campaign called "Melbourne" is not targeted to Melbourne because of its name. Record the owner, the purpose and the key settings outside the name. Use labels for categories that change.

The vertical bars are separators inside the names. Keep "test", "copy" and "final v2" out of names that will still be there in a year.

Copying a campaign

Google's copy and paste page gives the route. Select the campaign under Campaigns, then Edit, then Copy, then Edit and Paste. The paste step has a checkbox to pause new campaigns after pasting. Use it.

A pasted campaign keeps the structure and settings. That includes ad groups, ads and keywords, plus negatives, targeting and bid strategies. The copy doesn't carry historical performance data or bid strategy learning. Performance Max campaigns can be copied but their listing groups are not. Copying between accounts needs Google Ads Editor.

Before the copy goes live, check:

• the name

• the geography

• the schedule

• the budget

• the bidding

• the goals

• the URLs

• the tracking

• the assets

• the exclusions

Skip that check and the copy goes live with last year's budget and this year's promotion.

A live duplicate is not a controlled A/B test. Use a supported experiment where one fits, or a documented staged rollout. Keep the original for history and rollback rather than deleting it. Do not expect a copied setup to produce identical results.

Review the structure before changing it

A restructure should answer evidence, not anxiety. Diagnose first.

In the first month, check eligibility and tracking first. Fix anything broken or overspending straight away. Then judge search quality and destination relevance against the business outcome, without restructuring every week.

Give a restructure the time our first 30 days of Google Ads guide gives a launch. Allow 4 to 8 weeks for a first read and about 90 days to judge cost per lead. Allow longer when the sales cycle is long.

Is the problem wider than the structure? Our guide for when Google Ads is not working works through the causes check by check. Our Google Ads audit scorecard is a prompt for the questions to ask of an existing account.
