Short answer
A Google Ads campaign structure is how you split an account into campaigns, which carry budgets and settings, and ad groups, which hold keywords and ads around one theme. For a small business, give each important service its own ad group, and its own campaign when it needs a separate budget. Google allows up to 20,000 ad groups per campaign and 10,000 campaigns per account.
How to use the Google Ads Campaign Structure Generator
- Enter your business type and your services or products, and mark the ones that matter most.
- Add your service area, monthly budget and main goal: calls, forms, bookings or sales.
- Pick the campaign types to consider and say whether you want a brand campaign.
- Review the campaigns, ad groups, budget split, negatives and checklists, and change what does not fit.
- Download the CSV or Editor paste file and build the campaigns in Google Ads Editor.
What does a good Google Ads campaign structure look like?
Think of it in layers. Campaigns carry the budget and the main settings, ad groups hold the keywords and ads for one theme, and each ad group should send people to the page that best answers its searches.
A practical rule for a small business: give a service its own campaign when it needs its own budget or goal, and its own ad group when it needs its own ads. A dental practice might fund emergency visits separately from implants, because the two differ in urgency and value.
Here is how that could look for a fictional practice, with one naming pattern throughout:
| Campaign | Ad group | Example keywords |
|---|---|---|
| Search | Brand | Calls | Practice name | [your practice name] |
| Search | Emergency | Calls | Emergency dentist | [emergency dentist], "same day dentist" |
| Search | Emergency | Calls | Toothache | "toothache dentist", [broken tooth repair] |
| Search | Implants | Forms | Dental implants | "dental implants", [implant dentist] |
| Search | Implants | Forms | Implant cost | "dental implant cost", [cost of dental implants] |
What does the generator build?
- Campaigns with a name, type, goal, suggested bidding and a budget share in percent and dollars, worked out from the monthly budget you enter.
- Ad groups for each campaign, each with a theme, 5 to 10 keywords with match types and a suggested landing page.
- A starter shared negative list to apply from day one.
- An asset checklist and a conversion tracking checklist, plus a naming convention to keep the account readable.
You can ask it to consider Search only, Search plus Performance Max, or Search plus Local Services Ads, with or without a brand campaign. The export has Campaign, Budget, Ad group, Keyword and Criterion Type columns, ready for Google Ads Editor.
How should you split a Google Ads budget across campaigns?
Put the most money behind the services that earn the most and draw the most ready-to-buy searches. The generator turns the priorities you mark into a budget share for each campaign, in percent and in dollars.
Keep the number of campaigns in proportion to the budget. Each campaign needs enough spend to collect clicks and conversions you can judge, and a few well-funded campaigns are easier to read than many thin ones.
To model clicks and leads from a budget, use the Budget, CPA and ROAS Calculator. Before you settle the split, check what Google Ads costs in 2026.
Brand campaigns
A brand campaign keeps searches for your business name apart from service searches, so people who already know you do not blur the numbers for people still choosing. Google's trademark policy does not restrict using trademarks as keywords, so other advertisers may bid on your name too.
Which checklists come with the plan?
The asset checklist covers what to prepare before launch. These are the Google numbers worth planning around:
| Item | Google's number |
|---|---|
| Responsive search ad headlines | 3 to 15, up to 30 characters each |
| Responsive search ad descriptions | 2 to 4, up to 90 characters each |
| Responsive search ads per ad group | At least 2 rated Good or Excellent (best practice) |
| Sitelinks | At least 2 to show; at least 6 for Good or better Ad Strength |
| Callouts | At least 4 recommended |
| Negative keyword lists | Up to 20 per account, 5,000 keywords each |
Sources: Google's pages on responsive search ads, Ad Strength, sitelinks, adding assets and account limits.
The conversion tracking checklist matters most: without conversions, you cannot tell which campaign earns its budget. Keep auto-tagging on, since it adds a gclid to your URLs and, in Google Analytics 4, auto-tagging is prioritized over manual tagging.
If you add Performance Max, expect GA4 to report it as Cross-network rather than Paid Search, under its default channel group rules.
Campaign structure mistakes to avoid
- One ad group for every service. The ads end up generic, and you cannot see which service pays for itself.
- Too many campaigns for the budget. Spread thin, each campaign gathers too little data to judge.
- Mixing goals. Keep calls, forms, bookings and sales apart when they need different landing pages or bidding.
- Launching without negatives. Apply the starter list on day one, extend it with the Negative Keyword Generator, and add real waste from the Search Term Analyzer.
- Loose ad groups. If a group's keywords need different headlines, split it with the Keyword Grouping Tool.
- Names nobody can read. Stick to one naming pattern so reports and filters still make sense months later.
