Google Ads Account Structure, explained properly.
What is Google Ads account structure?
Every Google Ads account uses three levels: campaigns, ad groups, and keywords plus ads. This hierarchy is one of the most commonly mismanaged parts of Google Ads. Think of it as a filing system: poor organisation makes it hard to spot performance issues and budget waste.
The three levels
- **Campaign level:** daily budget, bidding strategy, location and language targeting, ad network and campaign type. - **Ad group level:** a themed cluster of keywords and the ads written for them. - **Keyword and ad level:** specific keywords with match types, negative keywords and the ads themselves. ### 1. Campaigns Campaigns are the top-level container holding budget, location targeting, ad schedule and bid strategy. A common approach separates campaigns by goal, such as brand defence, lead generation and retargeting. ### 2. Ad groups Ad groups contain themed keywords plus matching ads. Every keyword in an ad group should be answerable by the same ad copy and the same landing page. ### 3. Keywords and ads Keywords trigger ads when people search. Each ad group should contain at least three responsive search ads testing different headlines and descriptions, with 5 to 20 closely related keywords.
Why account structure matters
Poor structure causes specific problems: - **Quality Score suffers.** Broad ad groups prevent tight ad-to-keyword matching, hurting Quality Score and inflating CPCs. - **Budget gets wasted.** Poorly grouped keywords receive uneven allocation regardless of conversion performance. - **Reporting becomes opaque.** Mixed themes hide profitability by topic. - **A/B testing breaks down.** Varied keywords prevent meaningful ad copy testing. Our PPC management always starts with a structural audit, because no amount of optimisation fixes fundamentally broken architecture.
What good structure looks like
For small businesses running search campaigns, a solid structure includes: - One campaign per major goal (brand, services, retargeting). - Ad groups organised by service or product theme. - 5 to 15 closely related keywords per ad group. - Three responsive search ads per ad group, with 8 to 10 headlines and four descriptions. - Negative keyword lists at campaign level.
Google Ads Account Structure: common questions.
How many ad groups should be in a campaign?
Most well-structured campaigns have between three and ten ad groups. Each should be tight enough that one ad copy and one landing page answer every keyword in it.
How many keywords per ad group is best?
5 to 20 is the typical sweet spot for tightly themed search ad groups. Below this, keywords may be oversplit; above it, ad copy loses relevance.
Should I separate brand and non-brand keywords?
Yes, almost always. Brand keywords convert at a much higher rate and a much lower cost. Mixing them obscures how your non-brand campaigns are really performing.
What is the difference between a campaign and an ad group?
Budget and settings live at the campaign level. Themed keyword groups and the ads that target them live at the ad group level.
What clients say about working with us.
“I've had the pleasure of working with Chris on several SEO projects for my websites in the health field. He was definitely been able to demystify things so that I felt able to make decisions with him and feel confident they were the right ones. For a non-techie, that is worth gold! I look forward to working with Chris again and warmly recommend him to anyone who - like me - is unsure about all things SEO.”
“I was recommended by my branding partner to use Chris and his team last year. I can’t recommend them highly enough. They are very responsive , easy to communicate with and great at translating techy stuff when needed. They are now an essential part of my business model”
“We've been working closely with Chris, Hannah and the team for over 12 months now. As a small company with ambitious growth plans, it was incredibly important that we made the right choice on who to trust with our SEO. 18 months later, we're totally thrilled with our experience so far and our growing online presence within our market. We'd happily recommend BTT and their services to other SMEs. Drop them an enquiry!”
