How to structure a Google Ads account

IN SHORT

A Google Ads account is organized in three layers: the account, campaigns that hold your location and budget decisions, and ad groups that hold tightly related keywords and ads. Structure the account around how you sell, control wasted spend with match types and negative keywords, and choose a bidding strategy your conversion data can support.

Campaigns and ad groups are a filing system for your goals. Group by what you sell and where, not by habit.
Match types decide how closely a search must match your keyword. Negative keywords block searches you never want.
Automated bidding needs accurate conversion tracking. Without it, the automation optimizes for the wrong thing.
Performance Max trades control for reach. It suits some businesses and not others.

The three layers: account, campaign, ad group

Google’s own documentation on account limits shows the hierarchy: an account holds campaigns, a campaign holds ad groups, and an ad group holds the ads and targeting items such as keywords (Google Ads Help, "About your Google Ads account limits"). Location targets are set at campaign level.

In practice, treat the campaign as the place where you decide a business question: which product or service, which place, how much to spend. Treat the ad group as the place where you decide a search question: which closely related searches share one set of ads.

The aim is simple. Every search that triggers one of your pay-per-click ads should meet an ad that speaks to it, which leads to a page that continues the same conversation. Structure is how you make that happen at scale, and it directly affects the Quality Score diagnostic that Google shows for each keyword.

How to build the structure step by step

Start with a list of the things you sell that make money, ordered by margin and demand. Each major service or product line usually earns its own campaign, because each has its own budget logic and landing page. A law firm might separate employment from family law. A shop might separate boots from jackets.

Split campaigns again where the budget or location decision differs. If you serve two cities and want to spend more in one, use two campaigns. Combining them forces one budget to cover both, and the platform will favor whichever looks cheaper, not whichever you value more.

Inside each campaign, create ad groups around one theme each, such as one service or one product type. Write the ads so the headline answers that theme directly. A common failure is one ad group with fifty unrelated keywords and a generic ad, which breaks relevance and makes results impossible to read.

Campaign: one service or product line, one location decision, one budget decision.
Ad group: one theme, a small set of related keywords, and ads that name that theme.
Landing page: one page per theme where possible (see Landing pages for ads).
Naming: use a clear scheme such as service, location and match type, so reports can be read at a glance.

Keyword match types and negative keywords

A keyword match type controls how closely a search must relate to your keyword for your ad to enter the auction. Google describes three (Google Ads Help, "About keyword matching options"). Broad match is the default and can show for related searches that do not contain your exact words. Phrase match shows for searches that carry the keyword’s meaning, including more specific versions. Exact match shows for searches with the same meaning or intent, and gives the most control with the least reach.

Google states that broader match types include the queries of narrower ones, and it recommends pairing broad match with Smart Bidding. The practical result is that broad match gives you reach and phrase or exact gives you control. Start tighter when the budget is small and you cannot afford to learn expensively. Loosen as you see which search terms actually convert.

A negative keyword tells Google which searches should never trigger your ad. Google’s documentation says negative keywords work differently from positive ones: a broad negative blocks only when the search contains all its terms, in any order, and negatives do not automatically cover synonyms or plurals, so you must add those yourself (Google Ads Help, "About negative keywords").

The working habit: read the search terms report weekly, and add negatives for anything irrelevant. A plumber should exclude “jobs”, “training” and “DIY”. A software firm selling to businesses may exclude “free” and “open source”. This single habit usually does more for wasted spend than any bid change.

Choosing a bidding strategy

Google describes Smart Bidding as a set of automated strategies that use Google AI to optimize for conversions or conversion value in each auction, using signals such as device, location, time of day, language and operating system (Google Ads Help, "Determine a bid strategy based on your goals").

The four to know are these. Maximize Conversions aims for as many conversions as possible within budget, with no cost target. Target CPA aims for conversions near a cost per action you set. Maximize Conversion Value aims for the most value within budget. Target ROAS aims for conversion value near a return on ad spend you set. Google notes that Maximize Clicks can suit new campaigns that lack the conversion data these strategies need.

Choose by what you can measure. If every enquiry is worth about the same, optimize for conversions. If sales vary widely in value, as in an online shop, pass the real value through and optimize for conversion value. Set a target only when you have enough history to know a realistic one. A target set too tight starves the campaign of volume, and one set too loose spends freely.

None of these strategies is smarter than the data it receives. Google says conversion actions you want to optimize for should be marked as Primary and that tracking must be set up correctly. If you count a page view as a conversion, the automation will find you more page views.

Performance Max: what it is and its caveats

Performance Max is a goal-based campaign type that runs across Google’s inventory, including YouTube, Display, Search, Discover, Gmail and Maps, from a single campaign (Google Ads Help, "About Performance Max campaigns"). You supply asset groups, which are collections of images, text, logos and videos, and Google’s AI combines them into ads.

The benefits are reach and less manual work. The caveats are control and visibility. You choose less about where ads appear, so results can mix high-intent searches with lower-intent placements. Google lists controls such as negative keywords, brand exclusions, audience signals and reporting by asset group and channel, which you should use rather than leave at defaults.

A sensible rule: build and prove a well-structured Search campaign first, so you know which searches and messages convert. Add Performance Max when conversion tracking is accurate, you have a clear goal, and you can feed it strong assets. Keep an eye on whether it is finding new customers or simply capturing people who would have found you anyway.

How to review an account

Review on a fixed rhythm. Weekly: search terms, spend against budget, and anything that stopped serving. Monthly: cost per conversion and conversion rate by campaign, ad group performance, and landing page performance. Quarterly: whether the structure still matches what the business sells and where it wants to grow.

Use Quality Score as a diagnostic, not a goal. Google states that Quality Score is not an input in the ad auction, and that its three components, expected click-through rate, ad relevance and landing page experience, are rated above average, average or below average against advertisers on the same searches over the last 90 days (Google Ads Help, "About Quality Score for Search campaigns"). A below-average component tells you where to look.

Check that the structure tells a story you can read. If a manager asks what an ad group is for and the answer takes more than one sentence, it is probably too broad. For the foundations of how clicks are priced, see What is paid advertising?.

Examples by industry

Illustrative scenarios, not client results. Pick the one closest to your business.

B2B SOFTWARE AND STARTUPS
A project-management software company selling to small agencies (fictional example). The company runs one campaign with all its keywords, and free-trial sign-ups come mixed with students and job seekers.
1. They split campaigns by use case, such as client approvals and time tracking, so each has its own ad group themes and landing page.
2. They add negatives for “free”, “open source”, “template” and “jobs” after reading the search terms report.
3. They mark the trial sign-up as the primary conversion and pass a qualified-lead event as a second signal, so bidding learns from real prospects.
Takeaway: Structure by use case, block the wrong intent with negatives, and feed bidding the action that predicts a customer.
ACCOUNTING AND FINANCIAL FIRMS
A small accounting practice with two offices (fictional example). The practice serves small businesses in two towns and wants more bookkeeping and tax enquiries.
1. They create separate campaigns for each town and each service, so budget can follow where the partners want growth.
2. They begin with exact and phrase match on service-plus-place searches, then review search terms before loosening.
3. They use a manual or conversion-based strategy until the account has enough enquiries to support a target.
Takeaway: Separate campaigns where budget or location decisions differ, and start tight when volume is small.
DENTAL AND HEALTH CLINICS
A physiotherapy clinic with three treatment areas (fictional example). The clinic wants appointment bookings, and a competitor’s name keeps appearing in its search terms.
1. They build one ad group per treatment area, with ads and a page that name that condition.
2. They add competitor and irrelevant searches as negatives, and keep ad text within the platform’s healthcare advertising rules.
3. They count booked appointments as the primary conversion, not clicks on the phone number alone.
Takeaway: One ad group per treatment, strict negatives, and a conversion that means a real booking.

Common mistakes

One campaign for everything. Budget flows to whatever looks cheapest, and you cannot tell what pays.
Ad groups with dozens of unrelated keywords. The ad cannot be relevant to all of them, so relevance and click-through suffer.
Never reading the search terms report. You pay for irrelevant searches for months without noticing.
Choosing Target CPA or Target ROAS with little conversion history. The target is a guess, and volume collapses or spend runs loose.
Counting low-value actions, such as page views or button clicks, as primary conversions. Automation then optimizes for them.
Leaving Performance Max on defaults. You lose control over where ads run and cannot tell which asset or channel works.
Changing structure and bids every few days. The platform resets learning each time and you never see a clear result.

Questions

How should I structure a Google Ads account?

Organize it by how you sell: one campaign per service or product line and location decision, one ad group per theme inside it, and a small set of related keywords and ads in each ad group. This keeps every ad relevant to the searches that trigger it and makes results readable. Add negative keywords to block irrelevant searches, choose match types deliberately, and point each ad group to a page that continues the same message. Start small, with a few campaigns you can manage well, and expand when you can see what converts rather than building a large structure up front.

How many keywords should be in an ad group?

There is no official number, and Google does not publish one. The useful test is whether every keyword shares one theme that a single ad and page can answer. For most small accounts that means a handful of closely related keywords per ad group, not dozens. If you cannot write one headline that fits all of them, split the group. Modern match types also cover close variants and related searches, so you rarely need every spelling as a separate keyword. Judge groups on relevance and on what the search terms report shows, not on keyword count.

Should I use broad match or exact match?

Use exact or phrase match when budget is small and you want control, and add broad match when you have accurate conversion tracking and an automated bidding strategy. Google states that broad match is the default and recommends pairing it with Smart Bidding, because the bidding uses signals to judge each search. Broad match without negatives and good tracking can spend on irrelevant searches. Whichever you choose, review the search terms report weekly, add negatives, and let the data decide which keywords to loosen or tighten.

Is Performance Max better than Search campaigns?

Not automatically. Performance Max reaches more of Google’s inventory from one campaign and needs less manual work, but gives you less control and less clarity about where results come from. Search campaigns give you control of keywords and ads and show exactly which searches triggered them. For most businesses, a sound Search campaign is the right first step, and Performance Max is an addition once tracking and goals are reliable. If your goal is local enquiries, test whether Performance Max finds new customers or just reaches people who were already looking for you.

How long does it take to set up a Google Ads account properly?

A well-built starter account takes days to a couple of weeks, depending on how many services you have and how ready your website and tracking are. Most of the time goes into keyword research, writing relevant ads, building landing pages and testing conversion tracking, not into clicking buttons in the platform. Expect the real learning to take several more weeks of data. Be cautious of any account built in an afternoon with a generic structure.
