Quick Definition #
In a search campaign, a campaign sets broad controls, an ad group organises a related theme, and keywords help match ads to relevant searches under the campaign’s targeting rules.
Campaign Level #
Use campaigns to separate meaningful differences such as budget, geography, language, campaign type, bidding approach or business objective. A campaign should have a clear purpose that can be measured.
Ad Group Level #
Group related keywords and ads around a coherent topic or user need. For example, a digital training provider might create separate ad groups for beginner courses and advanced courses if the searches and landing pages differ substantially.
Keyword Level #
Keywords are targeting inputs, not necessarily exact phrases that users must type. Match types determine how closely a search must relate to a keyword, and actual matching can depend on meaning and context. Search terms reports help reveal the queries that triggered ads.
Structure Example #
| Level | Example | Purpose |
|---|---|---|
| Campaign | Search – Digital Courses – Leads | Budget, geography and lead objective |
| Ad group | Beginner Digital Marketing | One focused search theme |
| Keywords | digital marketing course for beginners | Relevant search targeting |
| Ad | Beginner course ad with clear benefits | Message aligned with the search |
| Landing page | Beginner course details and enquiry form | Complete the user’s next step |
How to Build the Structure #
- Research search themes and user intent.
- Separate campaigns only where settings or budgets need separate control.
- Group related keywords by meaning and landing-page intent.
- Write ad messaging that answers the theme.
- Choose a relevant landing page for each ad group.
- Review search terms and conversion data after launch.
Common Mistakes #
- Combining unrelated keywords and ads in one ad group.
- Creating an ad group for every tiny keyword variation.
- Sending every ad to the homepage.
- Assuming keyword text alone controls every search match.
- Ignoring the actual search terms and user outcomes.
Key Takeaway #
Organise around shared intent and relevant landing pages. A good structure supports control and learning without unnecessary complexity.
