The Perfect Google Ads Campaign Structure
for Local Services

The best structure for local services is one campaign per service area or budget tier, with 5-10 ad groups organized by service type or intent. For example, a plumber campaign might have ad groups for 'Emergency Plumber,' 'Water Heater Repair,' 'Drain Cleaning,' 'Leak Repair,' and 'Bathroom Remodel.' Each ad group should contain 5-10 tightly themed keywords and 1-2 RSAs with headlines that directly reference those keywords. This structure ensures high Quality Scores because your ads match the search intent at the ad group level.

Aim for 5-10 ad groups per campaign for a local service business. Fewer than 5 usually means your ad groups are too broad and mixing different intents. More than 15 can become difficult to manage and may split your budget too thin — each ad group needs enough impressions to collect data and optimize. The key principle is that every keyword in an ad group should logically share the same ad copy. If a keyword doesn't fit the headlines of its ad group, it belongs in a different group.

5-10 keywords per ad group is the sweet spot for local service campaigns. This gives Google enough keyword variations to match search queries while keeping the theme tight enough for high ad relevance. Include a mix of match types: 2-3 exact match for your highest-intent terms, 3-5 phrase match for moderate variations, and optionally 1-2 broad match (only if you have strong negative keyword coverage and conversion tracking). Avoid keyword stuffing — 30+ keywords in an ad group almost always means the theme is too broad.

For most local businesses spending under $5,000/mo, one campaign with well-organized ad groups is the right starting point. Multiple campaigns make sense when you need separate budgets for different service lines (e.g., residential vs commercial), different geographic targets, or when one service type has dramatically different CPCs. Running one campaign keeps your budget flexible — Google can shift spend toward your best-performing ad groups automatically. Split into multiple campaigns only when you have a specific budgeting reason to do so.

SKAG stands for Single Keyword Ad Group — a structure where each ad group contains exactly one keyword. SKAGs were popular in the era of Expanded Text Ads because they allowed perfect keyword-to-headline matching. With Responsive Search Ads (RSAs), SKAGs are largely outdated and counterproductive. RSAs need volume to test headline combinations, and SKAGs fragment your traffic across too many ad groups. The modern best practice is themed ad groups with 5-10 related keywords sharing RSAs that cover the theme. Google's own guidance has moved away from SKAGs in favor of consolidated, theme-based structures.
